The zipDB and syszlib code uses the zlib library (copyright (C) 1995-2004 Jean-loup Gailly and Mark Adler). Syszlib was ported to PalmOS by Tom Zerucha and the ARM-acceleration is due to Justin Clark. The gorgeous Velo - Grayhide skin is copyright by Oscar Ljundberg and included by his kind permission. The Astronaut skin and all skins with "NASA" in the name are based on NASA photographs, but no endorsement by or affiliation with NASA is implied. The original black and white version of the home icon was drawn by Jeff Frankus, to whom I am grateful for permission to use. The configure icon is licensed under the BSD license, below. The Horizons skin is copyright (c) 2006 "filber" and is included with his kind permission under the by-nc-sa 2.5 (included) Creative Commons license with the additional provision: "It is additionally permitted to include this skin with any legally licensed distribution of mySkin as well as to make unrestricted modifications and copies of it for one's personal use, as long as one does not distribute these to others."

1. This is a legally binding agreement between you and Alexander Pruss. You agree to this agreement by USING mySkin, where "USING" is defined as copying mySkin or any portion of it into a PDA's storage (of any sort: permanent or not, hard disk or solid state), or executing mySkin or any portion of it, or making or distributing further copies of mySkin. If you disagree, you must destroy all your copies of mySkin, or portions thereof, including, if you have it, and the mySkin Registration/Upgrade Data or portions thereof.

2. mySkin is distributed WITHOUT ANY WARRANTY, implied or express, without even any implied MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE warranty. USE AT YOUR OWN RISK. It may crash and burn, destroying your data, but Alexander Pruss may not be held responsible for this. You agree that you know this and you agree that you know that a fully backup of all your PDA data should be made before using.

3. You can re-sell or give away your copy of the mySkin Registration Data or of the mySkin full version, but only if you delete all of your own copies of mySkin's Registration Data and require the recipient to adhere to this agreement, and only if have never violated this agreement. You may install mySkin and, if and only if you have a legally licensed copy, its Registration Data on one PDA. You may make as many backup copies of mySkin and its Registration Data for your own use as you wish, providing that (a) you ensure that nobody else has access to these copies or portions thereof (thus, you may not place these copies on a network in a way that allows others to access them), and (b) that only one PDA at any given time has mySkin, its Registration Data and/or a portion thereof ACCESSIBLE to it, where a copy of mySkin or its Registration Data is defined as "ACCESSIBLE TO A PDA" providing that it is loaded on any storage, internal, external or networked, that the PDA is hooked up to, in such a way that it is possible to transfer data from that storage device to the internal memory of the PDA. Sale or transfer under any other conditions is prohibited.

4. You are not permitted to use mySkin in an objectively immoral way or in a way that violates copyright or trademark law, whether international or specific to your location. In fact, you are not permitted to use mySkin in a way that violates any law operative at your location. The one exception is with respect to laws limiting freedom of expression within a totalitarian state. For the purposes of this agreement, anti-pornography, copyright and trademark laws do not count as "limiting freedom of expression" and the United States of America does not count as a "totalitarian state".

5. Any attempts to allow mySkin to load or merge skins (other than the built-in OS skin) without registration after the expiry of the trial period are violations of this agreement. Furthermore, this agreement prohibits you from attempting to find, discover or communicate any methods or tools for continuation of non-ROM skin loading/merging after the expiry of the trial period.

6. As a special permission that may be withdrawn at any time, and that is automatically withdrawn forever (unless explicit notification to the contrary is received from Alexander R. Pruss) whenever any of the terms of this agreement have been violated, you may distribute unmodified copies of the unregistered shareware version of mySkin to anyone you wish, providing that (a) all copies include in unmodified form mySkin-Installer.prc and this readme.html file, (b) this license is binding on all recipients, (c) any website on which the data is posted neither contains or links to any methods or tools for continuation of use of the skin loading features (other than restoration of ROM skin) after the expiry of the trial period. The special permission for distributing the unregistered shareware version may be withdrawn either by personal communication from Alexander Pruss (by voice, email or writing), or by a general notice posted at www.prussfamily.us/SkinT3Notices.html. You are responsible for reading any such notices before attempting to distribute.

7. The Registration Data for mySkin contains a complete computer program copyright (c) 1995 Alexander R. Pruss, distributed in source code format. Copying, distribution or re- distribution of this program is absolutely forbidden by this agreement except under the conditions of point 3 as limited by the rest of this agreement.

8. You are not permitted to use mySkin in an objectively immoral way or in a way that violates copyright or trademark law, whether international or specific to your location. In fact, you are not permitted to use mySkin in a way that violates ANY law operative at your location, with the one exception being laws unduly limiting freedom of expression within a totalitarian state. At least for the purposes of this agreement, anti-pornography, copyright and trademark laws do not count as "unduly limiting freedom of expression" and the United States of America does not count as a "totalitarian state".

9. You have explicit permission from Alexander R. Pruss to use your mySkin registration data in a Clie PDA in conjunction with ClieSkinner if you move from a Palm T3/T5/TX or LifeDrive to a Clie NR/NX/NZ/TH/UX, or to use your ClieSkinner registration data in a Palm device if you move from a Clie to a Palm device, assuming you have deleted the relevant registration data from your previous PDA unit. mySkin registration data is compatible with ClieSkinner and vice versa. The same goes for SkinTW! on the Tapwave.

Make a backup!

You should make a backup before using this software.

Trial, registration and free version

mySkin comes with a free eight day trial during which time it is fully functional. After that, the ability to load or merge skins other than the OS skin, or to move skins to VFS, is disabled. The ability to control display depth, change clock and Graffiti button color, or control whether application buttons are shown in full color or two-color mode remains in the free version that you get after expiry of the trial period. Likewise, the skin crash protection features should continue to work.

You can register at palmgear.com to restore all the functions of the full version.

Introduction and quick start

Graffiti writing area and statusbar (also known as DIA, or Dynamic Input Area) skins allow you to change the look of your Palm Tungsten T3, T5, TX and LifeDrive. On other devices, it functions as a free hard-key macro program, with all skin-related functions disabled. mySkin lets you load and manage these skins. (Do not run this on other models than the T3, T5, TX or LifeDrive--it will probably crash them.) You can also create new skins by recolorizing the old ones (including the built-in one, if your local copyright law allows it) and by inserting a photograph from your card or main memory into a skin (T5, TX and LifeDrive only) by tapping on the photograph icon.

mySkin used to be known as "SkinDIA!" and "SkinT3!": upgrades from these products to mySkin are free.

If you are using a Tungsten T5, TX or LifeDrive with skins designed for the T3, you should read the instructions carefully.

For a quick start, install mySkin-Installer.prc (via hotsync to RAM or Program Memory), and run it if it does not start automatically. This will put "mySkin" and some support files on your device. Then on a separate hotsync, install some skins (if the skins are not T3-specific skins, you can install them on the initial hotsync).

mySkin includes VFS support which lets you move your skins to SD or other media and has support for 16-bit skins. You can register the trial version on palmgear.com.

Where to get or how to make more skins

Most of the following links are for Graffiti skins designed for the T3. But since mySkin lets you use T3 Graffiti skins on your T5, TX or LifeDrive, this shouldn't matter. But make sure you read the instructions carefully when cross-loading skins.

Generating skins

Using mySkin

Inserting photographs

If you have a T5, TX or LifeDrive, you can use mySkin to create Graffiti skins by inserting photographs that you have on your PDA into the input / statusbar area. The photographs must be accessible to the Media application on your PDA, and can be in main memory, in the "Photos & Videos" folder on the Internal Drive (T5 and LifeDrive) or in the DCIM folder on an SD card. You can copy photos to your PDA by using the Media option in Palm Desktop, or, on the T5 and LifeDrive, by using other Palm-supplied software. See the instructions that came with your PDA.

Once you have copied the photographs to your PDA, simply tap on the "photo" icon in the upper-right corner of the mySkin screen (or choose the "Put photo into skin..." option in the "Files" menu). Then tap on "Get photo". You may rotate the photo. To select the region you want to be used for the input area, select a region by tapping within the selection rectangle and dragging to move it, and by dragging corners to resize the rectangle. Once you have selected the area, tap on "Go". You can also use the checkboxes to choose which parts of the skin the photo goes into. You can use the same or a different photo for the landscape-orientation skin as for the portrait-orientation skin, but you do need to separately insert the photo into both. To do this, after inserting the photo in one orientation, just rotate your display (or tap on the drop down box), select a region again, and tap "Insert photo" again.

You can also select the color for elements like the dotted lines in 3-cell mode and the captions for the different input cells.

Recolorizing

If you don't like the color of a skin, you can recolorize the whole skin (this includes hex keyboard skins). Simply tap on the colorful rectangle and select a color. Darker and lighter areas will use different shades of the basic color you are choosing. This can be done with any skin and works very nicely with the built-in OS skin (note: Colorizing the built-in OS skin causes a modified copy to be made in your device's memory. Make sure your local copyright law allows this, e.g., under fair-use doctrines, before doing this. And distributing the modified copy is very likely to be illegal.) There are some advanced options if you choose "Advanced colorize skin..." instead.

Desktop software

Pre-made skins

There are also several free 16-bit skins included, especially the gorgeous Horizons skin by "filber", and a beautiful 8-bit Velo Grayhide skin included by courtesy of its author, Oscar Ljundberg.

Upgrading or uninstalling

If you are upgrading from a previous version, hotsync mySkin-Installer.prc to your PDA. If the previous version number is lower than 1.40, make sure you have disabled "RAM icons" in the old mySkin version's Preferences dialog first. To re-enable some features and bug fixes, simply run mySkin after installing. Some new features and performance improvements may require re-loading a skin.

Note that if you are upgrading from mySkin 2.05-2.07 or myKbd 1.00-1.01, you will need to uninstall the previous version before installing a new one. Do this with the "Uninstall" option in the "File" menu.

If you have IconFix enabled for all applications, you will save some memory by disabling IconFix for all applications, deleting IconFix and then using the "Full-color icon mode" option in the "Color" menu of mySkin. This will require a soft reset.

To uninstall mySkin, you should choose the "Uninstall" command in the "File" menu. You may wish to delete the skins first, as the "Uninstall" leaves them alone, or you can afterwards manually delete all the skins using a file manager or the Launcher's "Delete" menu option.

Note that if you ever wish to delete mySkin directly in Filez or another file manager, its name is shown as "SkinDIA!" for historical reasons.

Instructions

Read all of these instructions very carefully, especially if using T3 skins on a T5, TX or LifeDrive unit.

Hotsync mySkin-Installer.prc to your PDA to install the trial version. If you have registered mySkin, hotsync mySkin_Registration.pdb to your PDA. As of version 1.40, you should then be able to simply hotsync skins, either to RAM or to a card's /PALM/Programs/mySkin directory, and then run mySkin. If you are running on a T3 or LifeDrive, make sure you have hotsync'ed and run mySkin-Installer.prc before hotsync'ing any skins. You also should not run mySkin from an SD card (though mySkin-Installer.prc can be run from a card to install mySkin), though storing skins on an SD card is highly recommended.

Skin types

T3 DIA skins come in three varieties: standard T3 DIA skins, F3T3AgendaBG skins and mySkin (also known as SkinT3! skins or 16-bit skins) universal skins. All three kinds can be loaded by mySkin. F3T3AgendaBG and mySkin skins work by far the most easily, and should work on the T3/T5/TX/LifeDrive with no problems. (Note that mySkin skins might not be "complete", i.e., may deliberately lack a number of resources. Missing resources will be filled in from the ROM skin by mySkin when activating the skin.)

The installation of standard T3 DIA skins differs between a T3, on the one hand, and the T5/TX/LifeDrive. This should be no surprise since standard T3 DIA skins are designed specifically for a T5/TX/LifeDrive. If you're not sure if something is a standard skin or not, assume it's a standard skin.

Installing standard T3 DIA skins on a Tungsten T3

Standard T3 DIA skins activate on a T3 automatically after being hotsync'ed to RAM, overwriting any previous standard T3 DIA skin. Typically they also force a soft reset on hotsync'ing. They also do not have any distinctive name in the database beyond the standard name "StatusBarResources". If mySkin finds that a standard T3 DIA skin got loaded into RAM since the last mySkin session, it will convert that skin to a mySkin skin, renaming it to a skin named "Unnamed DIA skin #X", and deactivate it. It will also attempt to activate the previously loaded skin. This means that you can install standard T3 DIA skins just by hotsync'ing them, running mySkin, and then renaming the "Unnamed DIA skin #X" skin to some more usable name.

However, all this is a bit of a nuisance given the reset that these skins cause. You have two other choices. The first is to load the skin onto an SD card instead of RAM, in the /PALM/Programs/mySkin or /PALM/Launcher directory. The second choice is to "fix up" the skin before hotsync'ing it, and convert it to mySkin skin format. This can be done by double clicking on FixUpSkin.exe on a Windows unit, and then selecting the skin to be converted to mySkin format. Such skins no longer self-activate. In fact, you should not attempt to activate them in any way other than by using mySkin. (Advanced users may be used to activating skins by renaming them and changing the creator ID. Do not do this with mySkin skins, as this may cause a crash.)

Installing standard T3 DIA skins on a Tungsten T5, Palm TX or a LifeDrive

If you hotsync a standard T3 DIA skin to the program memory of a T5/TX/LifeDrive, you may have problems, including a crash and losing the Graffiti area completely (in which case you should do a warm reset and after it run mySkin to recover). Therefore, hotsync'ing a standard T3 DIA skin to program memory on a T5/TX/LifeDrive is definitely not recommended.

Therefore, you should do one of three things.

Option 1: Instead of loading the skin to program memory, you could load it to the internal drive (or an SD card) in the /PALM/Programs/mySkin or /PALM/Launcher directory.

Option 2: "Fix up" the skin before hotsync'ing it, and convert it to mySkin skin format. This can be done by double clicking on FixUpSkin.exe on a Windows unit, and then selecting the skin to be converted to mySkin format. Such skins no longer self-activate and you should not attempt to activate them in any way other than by using mySkin.

Option 3: The current version mySkin has "Cross-Load Protection". Make sure that either you have at some point run mySkin or you have installed it via hotsync (rather than copying from PC to card and from card to RAM). Then you can hotsync new skins without using FixUpSkin. Note that you must use hotsync if you do not use FixUpSkin--copying skins to a card and then copying them from card to RAM via a utility like Filez will not activate Cross-Load Protection for the skin. This installation method will result in going back to the standard OS skin--you will need to go to mySkin to load the newly hotsync'ed skin or some other skin.

Using mySkin to load and modify DIA skins

mySkin needs enough memory to make an extra copy in RAM of the skin being loaded. If it lacks this memory, it may crash. (For partial skins being loaded, enough memory for the full skin, after adding components from the base skin, is needed.)

To deactivate mySkin, simply load in the "Built-in OS skin".

The "to SD" (or "to Drv") button lets you move a skin to an SD card or Internal Drive (use the configuration form --tap on the wrench ()-- to control the destination). To copy a skin instead of moving it, use the "File" menu.

Tapping the menu button, brings up a menu. In the "File" menu there is a useful function to move all skins from RAM to an SD card or internal drive (VFS is the general name used), to copy (not move) one skin to VFS and to copy or move the skin from the card to RAM. There is an options menu with many useful preferences. There is a "Merge" menu for combining resources from different skins--see further on down.

Using the "Color" menu also lets you modify the currently loaded skin by changing the clock color and the color of the two-color buttons in the Graffiti area. Newly loaded skins can override these settings. You can also control whether application icons are shown in two-color mode, which is the system default, or in full-color mode. This used to require IconFix which created overlays that took up some memory and didn't work for all icons. Now it works for all icons without any such overlays. (You can disable IconFix support for all icons and still use this option. Or you can keep mySkin set in "two-color" mode and use IconFix to control which icons are specifically shown in full color.)

You can control the text and interstices color in Palm-style (rectangular key) keyboards.

Whenever a setting in the "Color" menu is changed, or a skin is loaded that affects the setting, a reset may be needed for the setting to take effect. You can, of course, choose "Later" to the question whether to do a reset, and make other changes first. Or if you're loading a skin that changed a color and you don't care about seeing this change, you don't have to bother with the reset. You can choose the option never to even ask about a reset. (But still the "Reset" button will magically appear on the screen whenever you do something that makes a reset appropriate.)

WARNINGS

  1. Loading a skin with mySkin makes an extra copy of the skin for as long as the skin is loaded as well as inserting any missing resources from the ROM skin. Whether making this extra copy in RAM of the skin and of some ROM resources is legal depends on local laws. The user is responsible for ensuring legality of use. Note that merging the OS skin or changing the clock color (and perhaps Graffiti button color) will result in an extra copy of the ROM skin being made in RAM, too.
  2. Changing the clock color and Graffiti button colors also modifies the RAM copy of the currently loaded skin. If the skin was distributed with a no-modification license clause, this may be legally problematic.
  3. Renaming an F3T3AgendaBG skin so that its name no longer starts with the magic string "F3T3AgSkin" will make it invisible to F3T3AgendaBG. mySkin should see it just fine, though.
  4. You cannot rename an F3T3AgendaBG to make its name start with the magic string "F3T3Agenda". Doing that would cause no end of trouble.

MessagEaseStamp and Fitaly users

MessageEaseStamp (MEST) and Fitaly come with its own custom skins of which only a few components are modified from the OS skins. You can mix-and-match the components of these skins with components of other skins. For your convenience, the MERGE menu includes a "MEST components" and a "Fitaly components" option which simply merges in the MEST-specific components from a MEST-specific skin (presumably F3T3AgSkinMEST3-007ANI or F3T3AgSkinMEST3-ANI007) or the Fitaly-specific components from a Fitaly-specific skin (presumably T3FitalySkin2, which if you keep it in RAM will have been renamed to "Unnamed DIA skin #x"). Thus, you can LOAD any custom skin not designed for MEST or Fitaly, and then MERGE the MEST- or Fitaly-specific components on top of it from the MEST or Fitaly skin.

Because MEST and Fitaly work in the Graffiti tri-cell panel while ATOMIK works in the keyboard panel, you might actually be able to use MEST/Fitaly and ATOMIK together, though there may be some incompatibilities.

SD card and other VFS support

mySkin can read skins from an SD card (and other VFS devices) and move them to VFS. Tap on the SD button (if you happen to have another VFS device, you can selected in the preference dialog). Skins are read from the PALM\Launcher, PALM\Programs\SkinT3 and PALM\Programs\AgendaBG directories on all available VFS devices. You can make mySkin start up faster if you keep all your skins in PALM\Programs\SkinT3 and/or PALM\Programs\AgendaBG and in the Preferences dialog disable the option to search PALM\Launcher.

It is not recommended that you load mySkin itself onto an SD card or other VFS device.

Instructions and tips for advanced users

FontSmoother compatibility

FontSmoother is a utility by the same developer, available on palmgear.com, that lets you use smooth (antialiased) fonts in a variety of sizes and styles (in fact, any Windows TrueType font can be converted). If you care about how your PDA looks, FontSmoother will likely make an enormous difference, besides letting you fit more information on screen with smaller fonts or improve legibility with clearer fonts of the same or larger size.

However, a very small handful of DIA skins seem to have an incompatibility with FontSmoother which causes the statusbar clock to be mixed up. To solve this, use the custom merge function in the Merge menu to merge in the clock backgrounds from another skin (e.g., the built-in OS skin, or one of the included skins).

(Note to skin developers: Please avoid skins where the clock background is a fully transparent rectangle.)

Macros

There is a sophisticated set of programmable macros available in mySkin. You can assign macros to the four application keys on the front of your PDA (the "hard keys" as they are known). In fact, you can assign a different macro to a short and a different macro to a long press. One nice application of this is that by assigning the "<recent&rt;" macro to a long press of the first button on the TX, you replace the system's recent applications list with mySkin's better list (better because you can add favorite applications to it for permanent listing with the Options | Favorites option).

If you would like to have more than eight macros, you might be interested in the developer's myKbd (also available from palmgear.com), which is available highly discounted for mySkin users. myKbd does everything mySkin does, but allows you to have custom hexagonal key keyboards in a skin, including ATOMIK, Metropolis (IBM's computer-optimized layouts for on-screen tapping), QWERTY and any layout you like via a free layout generator. These keyboards also have two (or more if you make your own) dedicated macro keys, and a two-tap way of generating about ninety more macros.

You can use the macros to generate boilerplate text or templates. Or you can use them to launch applications and Desk Accessories, run control panel entries, tap on menu entries, etc.

To enter a macro, go to the Keyboard configuration form (Menu | Options | Hard key macros) and tap on the "Macros" button. Now tap on the "Hard key macro" field. To assign a macro to one of the four hard keys on the front of the PDA, tap on the field, and then press the hard key. You can select whether the macro is assigned to a normal short press, or to a one-second hold. On the T5, TX and LifeDrive you can also assign a macro to a one-second hold of the center key. To do that, just tap on the field and press the center key. Then tap on "Macro text" field and enter the text you would like to insert whenever you activate the macro.

You can include special commands like <hotsync> or <launcher> by choosing them from a drop-down list.

Possibly useful commands include the <tap> and <menu> commands which let you tap on a particular button (only buttons with standard text labels work) or on a particular menu entry. If you choose these commands from the drop-down list, you will be asked for the text to select. (With the <menu> command, if you leave this blank, you will simply pop up the menu.) When the macro is activated, myKbd will look for that entry. It first looks for the entry exactly as you entered (but in a case-insensitive way, so "about" matches both "about" and "About") and if it doesn't find it, then it looks for an entry that begins with the text you entered (thus entering "<menu about>" will result in a selection of "About myKbd" when activated within myKbd).

It is recommended that special commands be entered through the drop-down list to minimize the danger of typos or syntax errors.

The <wait nnn> command waits for nnn milliseconds (i.e., for nnn/1000 seconds). This is useful after <run> because it can be used to give the application some time to start up. The <waittitle ttt> command waits for a window whose title starts with ttt (case insensitive).

Macros may not be compatible with all applications. To interrupt a macro that is playing, tap on the screen, but not on exactly the same pixel where you tapped to start playback if you did so via a tap.

Macros assigned to the four application keys ("hard keys") may interfere with special functions in some applications that use these keys for their own purposes. This is particularly likely in a game. You can tap on "Options" in the Macros dialog to choose for which applications hard key macros are active.

Limitation: Macro playback currently stops when mySkin is launched, including when it is launched from the skin-switching macro commands.

Touchscreen calibration

The built-in Palm touchscreen calibration only calibrates over the top square area of the screen. This means that the calibration is optimal for tapping within that area, but not for tapping on keyboards (e.g., ATOMIK or MEST or the Palm QWERTY keyboard) in the input area. Choosing Menu | Options | Calibrate lets you calibrate the touchscreen over the whole of the screen.

Once you get the calibrate screen, just tap on the red dots in the middle of the calibration X's. You must tap on at least two of the X's. If you find you tapped too far away from where you meant to, you can restart the calibration process. Once you tap on two X's, you get an "OK" button to finish calibration. Try not to reset the PDA in the middle of calibration or you will start up in an uncalibrated state.

You can keep on tapping on X's for as long as you like, and mySkin will average the tap values for greater precision. I recommend a minimum of four taps.

TX home button

The Palm TX does not include the useful home button in the status bar that the T3, T5 and LifeDrive did. mySkin brings it back in the place of the search button. Just go to mySkin's configuration form () and turn it on. You can hold the stylus on it for about a second to pop up a list of the last couple of applications run. (Note that those applications available via hard keys are omitted.) You can choose whether you want the search function to work by holding down the statusbar menu button. If not, you will get a search option in the popup list of last applications instead.

You can even set some applications and Desk Accessories to show up permanently on the popup list. To do this, go to Menu | Options | Favorites, and add these applications to your Favorites list.

Tap on edge toggles statusbar.

This option allows you to hide/show the statusbar by tapping on its outer edge (the bottom edge in portrait, the right edge in right-handed landscape, the left edge in left-handed landscape), just against the screen frame plastic. Some applications may not be compatible with this.

Graffiti State Indicator

With the Palm TX, Palm has removed the venerable Graffiti State Indicator which shows auto-shift and other states. You can bring it back by installing the Graffiti State Indicator hack. See the instructions here.

Advanced colorize skin

If you just want to change the color of some skin elements, use the "Advanced colorize skin" command in the "Color" menu. Check the skin elements you wish to colorize. Tap on the color box for the destination color to set that.

There is a drop-down list setting the colorization mode. There are three options:

You can also select whether you are creating a 16-bit or an 8-bit skin. 16-bit skins will have more precise color gradients, while 8-bit skins take up less memory.

Skin compression

zlib-based skin compression is supported by the current version of mySkin. To compress a skin on your PC, run the enclosed zipDB.exe (in the advanced/ directory) program and select the skin. (You can also run it non-interactively from a commandline via zipDB -n filename.prc.) This will save ten to eighty percent space, at the cost of slightly slower skin loading. When you first run mySkin it will automatically install syszlib.prc (the ARM version, to be precise). If you distribute compressed skins, make sure you tell users to upgrade to version 1.45 of mySkin or version 1.00 of myKbd before installing the compressed skins.

A handy tip for compressing skins right on your PDA is to move them to an SD card or Internal Drive, run "Drive Mode" or "Card Export", and then compress them with zipDB on your PC.

Flash ROM

It should be theoretically possible to store mySkin and the skins not just in VFS but in flash ROM via some utility like Jackflash. I have not tested this configuration. One important caution. Before you do that, make sure the skins are "deactivated" by either running them through FixUpSkin or by installing them and running mySkin. You should not put the mySkin StatusBarResources database into ROM.

Merging skins

You might like one set of components of one skin and another set of components of another. For instance, you might like the status bar from one skin but want to stick with your OS's built-in Graffiti backgrounds. You can do that with mySkin by using the "merge" options. First, use the "Load" button (or just press the five-way navigator) to load the skin you want for most of the components. Then highlight another skin by tapping on its name, and pull down the menu (tap on the "mySkin" title bar), go to the "Merge" menu, and choose which components you want to merge in. If you want more precise control, choose the custom merge option.

The "Merge all" option is useful for "partial" skins. These are skins that do not include all components. For instance, some "partial" skins may include only buttons or only Graffiti backgrounds. Normally when a "partial" skin is loaded, the missing components are supplied from the built-in OS skin. But if you load the skin via the "Merge all" option (or in fact via any merge option), the previously active skin's resources are used for the resources missing in the skin loaded.

For instance, the included GeekySkin only has Graffiti area backgrounds. Suppose you want to use these backgrounds together with the buttons, keyboards and statusbar from MyFavoriteSkin. Normally loading GeekySkin will get you buttons, keyboards and statusbar from the OS. However, you can instead load MyFavoriteSkin and then use "Merge all" to merge in the GeekySkin's Graffiti area backgrounds, creating a hybrid in memory.

It is possible that creating such a hybrid might violate copyright laws. Consult your local law and any license agreements with your skins and software.

Screen shots

If you make your own skins from scratch or by mixing and merging components, you might wish to show off your creations. There is an option in the File menu to save a screen image, in .bmp format, of the Graffiti/statusbar area in the root directory of your card or Internal Drive (use the Preferences to set the precise destination). If you want to show off different panels and orientations, you can save multiple images, e.g., make one in portrait and one in landscape mode. The .bmp file has a filename based on the name of the last skin you loaded/merged.

If you are a skin designer or you want to be able to browse a large skin collection on your desktop, there is an option to dump images of all loaded skins. This works very slowly.

Note that each image takes about 150k of space.

Crash protection and RAM icon on clock popup

Currently, all methods of loading DIA skins other than mySkin apparently cause a crash when you load a skin and then pull up the clock popup (by tapping on the statusbar clock) eight times. Obviously, you don't do this eight times in a row, but the count appears to be cumulative (unless you do a reset in the meanwhile), so this means that if you load a skin without using mySkin, you might get a crash. The crash is due to a bug or poor programming practice in the ROM code handling the RAM (or "Device" on T5) icons in the clock popup. It is not currently known if this is an issue on the TX.

mySkin protects against this crash in two ways, depending on whether the "support RAM icons in clock popup" option is activated in the mySkin preferences:

Note for skin designers: If you want to create skins that do not cause this crash and that can be loaded by users who do not have mySkin, you should simply omit abmp resources 19520-19528 from your skin. This implements the first of the two solutions above at the level of your skin. ( Note that if the user loads in the skin with mySkin and RAM icon support activated, the default icon from the OS will be used, so the skin will look better.)

Display bit depth

The T3 can display in 1-bit (monochrome), 2- and 4-bit (grayscale), 8-bit and 16-bit color. Since skins look different in the different settings, mySkin lets you change the current depth setting to look at a skin at a different setting by going to the Options menu.

Using the Options | Preferences dialog (or the button) form, you can also make the current depth setting the default for applications. Some applications override the default, but many do not. Higher bit settings will make applications use more memory, but perhaps will improve quality. And 16-bit display mode is needed to make full use of 16-bit skins. The default depth setting is set back to 8 after a soft reset. There is an option in the Options | Preferences dialog to force the current setting to stick after a soft reset.

There are some third-party utilities that also set screen depth. Some of these may interefere with mySkin's attempt to set the default system depth. (Butterfly is reported to do so in the case of ClieSkinner on the TH-55.) If you are running such a utility, use it rather than mySkin for setting system depth or deinstall it.

16-bit skins

To improve quality, you can use 16-bit skins. These display correctly in both 8- and 16-bit screen modes, though look best in 16-bit modes. For instance, GeekySkin is a 16-bit skin.

Not all applications support 16-bit display. Those that do not will display the skin in downgraded 8-bit mode, though should still work. In the Preferences, there is a "dithering" option in the preferences to control how the skin gets downgraded. The "auto" option leaves it up to the skin designer. (Currently, all skins are released with dithering enabled.) When dithering is on, 16-bit images displayed in 8- bit mode are more fuzzy but have better color fidelity, while without dithering the images are sharper but the color fidelity suffers. Which is the better choice depends on the skin. You will need to reload the current skin for this option to take effect as it only affects skins at loading time. Note that turning off dithering increases the memory usage.

For those applications that do not support 16-bit display, I include a copy of Force16 in the advanced/ directory. Make sure you read its documentation carefully before installing.

Warning: Support for 16-bit skins may result in problems with some backup software because the mySkin internal databases have an oversized (>65000 bytes) resource. For instance, Backupman may skip the mySkin internal databases when restoring, but seem to work fine otherwise. In general, backup software may ask whether to skip the StatusBarResources database when restoring due to out of memory or other errors--this is because of the oversized resource. Just say "yes" to any skip or delete prompts for this database. mySkin will regenerate it next time you load a skin.

Making 16-bit skins requires generating the appropriate 16-bit resources. The only catch is that if you do that, some abmp resources might end up exceeding the 65000 byte limit, and then you will be unable to copy or load the skin. mySkin allows a workaround for this limit. An abmp resource may be split into two resources, an abmp resource that is exactly 65000 bytes long and a continuation resource of type 2bmp and the same id. When loading, mySkin will simply merge the two binary resources together into a single image.

Compacting, converting and saving skins

There are options in the "File" menu to convert skins to mySkin format as well as to compact them. These operations only work on skins in RAM. To perform them on skins on a flash card, move them to RAM, perform the operation, and move them back to the card.

Compacting removes from a skin all resources that duplicate resources found in ROM and compresses the remaining resources. This saves memory. Compacting also changes the "Merge" behavior of the skin. Merging loads in all the resources from the skin, including any resources that duplicate those in ROM. After compacting, most of the latter will not be loaded by a "Merge" function (except for resources that are closely logically tied in such a way that they should not be separated, such as various keyboard resources), which actually should be nicer behavior. Compacting also automatically converts the skin to mySkin format. I recommend doing this, if only to save memory.

Conversion is useful because skins in F3T3AgendaBG format cause trouble for some backup programs. Note that when one converts an "F3T3AgendaBG" skin the "F3T3AGSkin" prefix is removed from the name, unless doing so is impossible due to another skin that the name would conflict with.

You can also save the currently displayed skin ("Save As..."), if copyright law allows this. This will create an extra copy of the skin. You can choose to compact the skin while doing this. Saving the skin also saves the button and clock colors (though not the full vs. two-color setting, which is not stored in a skin). Saving is useful when you have customized the skin via merge and color operations.

Compacting is quite useful in conjunction with special skins that change only a few components.

mySkin skin format

The mySkin skin format uses the Creator ID 'T3sk' and type 'rsrc'. Moreover, no 'ovly' resource is permitted: instead, the data that normally goes in the 'ovly' resource should be placed in the 'OVLY' resource. It is a good idea to omit resources that are just direct copies of what is in the ROM.

WiFi skinning

Information for users: Some skins come with a WiFiSlip.prc file that lets you skin the WiFi icon in the status bar. I do not recommend installing this file. If it's designed for a different model PDA than yours, it could cause a crash. A better solution is to use the FixUpSkin.exe program and give it the WiFiSlip.prc file as input. This file will then become a mySkin skin named "Converted WiFi skin [xxxx]". You can use mySkin, then, to merge this skin on top of the non-WiFi portions of your skin.

Information for skin developers: To skin the WiFi icons in the status bar, simply include the requisite 'abmp' 25100-25262 resources (look at WiFiSlip.prc on your device) inside the skin database. mySkin takes care of the rest.

Emergency recovery

If you load in a really buggy skin on any model or hotsync a standard T3 skin on a T5/TX/LifeDrive, you could have continual crashes on reset. To fix this, you can try to do a warm reset (navigator-up plus reset) and then load the Built-In OS Skin in mySkin. The input area may not be working at this point. To get to the Launcher, you may need to hold down the navigator button on the T3, or else press the Launcher button on the T5/TX/LifeDrive. If mySkin is crashing or cannot run after a warm reset, get a file manager like Filez. Switch the input area to Graffiti. Delete the "StatusBarResources" file in RAM (not in ROM!) to uninstall the currently loaded skin.

Note that if you ever wish to delete mySkin directly in Filez or another file manager, its name is shown as "SkinDIA!" for historical reasons.

Developer information

Partial source code is available on handypalmstuff.sf.net.

There is one API officially exposed by myKbd/mySkin. Sublaunch with globals enabled and launch code sysAppLaunchCmdCustomBase. If the cmdPBP argument is NULL or an empty string, this loads the previous skin. If it is a non-empty string, myKbd/mySkin loads the first skin in its list order it can find with the database name specified in the string. The skin may be on an SD card in any of the directories myKbd/mySkin searches. To load the default system skin, use "StatusBarResources". id = DmFindDatabase( 0, "SkinDIA!" ); // myKbd/mySkin has this dbname
if ( id == NULL ) {
// no SkinDIA!
}
SysAppLaunch( card, id, sysAppLaunchFlagNewGlobals,
sysAppLaunchCmdCustomBase, // this is crucial!
skinDBName,
&result );
