NOTE: The remainder of this README applies only to the 7 accessibility 
      themes in this module:

- HighContrast[LargePrint][Inverse]
- LowContrast[LargePrint]
- LargePrint 

0. Default Theme

All the a11y themes in this module inherit from the 'mate' theme.
The 'mate' theme is in the mate-icon-theme module, and has to be built and installed separately.

1. Editing the gtkrc files

The files for each a11y theme are currently generated by Each file is the concatenation of these files:


It follows that you should NOT edit directly. Instead, edit the appropriate .rc file, then re-autogen before building.  This obviously kind of sucks, but it was the only way I could get it to work at the time :/

2. Adding new icons

The module is currently configured to make it easy to add or remove a stock icon from all themes at once, but not so easy to do so on a per-theme basis.  This works well for now but probably won't if we want to make this a more general theme repository.

So, to add a new gtk stock icon to all themes:

- Add the icon's filename to common/
- Add the line you want to appear in the themes' RC files to the appropriate common/*.rc file
- Add the icon files, each with the same filename, to all the <theme>/pixmaps/ directories.

MATE icons that are themed via the icon theming mechanism (as specified on are currently still added individually in each <theme>/icons subdirectory. E.g. to add a new 48x48 application icon to all the themes, you have to modify each <theme>/icons/48x48/apps/ individually, and add the appropriate icon file to each <theme>/icons/48x48/apps directory.

3. Changing icon sizes

The icon sizes for ALL the LargePrint themes are defined in  Changing them here will affect all LargePrint themes.

4.  Changing colours

To change the colours in a particular theme, edit its <themename>/gtk-2.0/<themename>.rc file.

5. Switching icon themes
In 2.2 and later, use mate-theme-manager, and choose the Icon theme from the Details subdialog.

In earlier versions of MATE, unless you're running my patched theme switcher dialog (patch in bugzilla,
#93486), you'll need to switch icon themes by hand using MateConf:

$ mateconftool-2 -s /desktop/mate/interface/icon_theme "<themename>" --type=string

6. To create low contrast icons in GIMP from the original coloured icon

Use the low-contrast-preset.scm GIMP script in this directory to create a low
contrast icon from a regular-coloured icon.  (Read the comments in the script
for instructions on how to install and use it.)  Thanks to Guillermo for
providing this!

Note: In GIMP, Input=0/0.6/255, Output=75/255 seems to give results 
closer to the icons Suzanna converted in Photoshop, but plugging these 
values into this script seems to give different results from doing it 
manually in the Levels dialog :/
