10.3.5 Installing Icons for Themes
The GNOME Desktop provides several themes that are designed for users with special
visual needs. For example, some of the themes are designed for users with low vision.
Several versions of icons might be required so that the icon can be displayed properly
in each theme.
You might need to install a new icon for an application. When you install a new icon,
you must create several versions of the icon so that the icon displays correctly in the
themes. You must create several versions of the following types of icon:
• Icons that are used within applications in the GNOME Desktop
• Icons that are used internally by GTK+ applications or GTK+ stock icons
You can create the icons in several formats (for example, Portable Network Graphic
(PNG) format). The suggested size of icons for the desktop environment is 48 x 48
pixels; at this size, most themes can rescale the icons.
When you install a new icon, create the following 48 x 48 pixel versions of the icon:
• Regular icon
• Low-contrast icon
• High-contrast icon
• Inverse high-contrast icon
If possible, also create 16 x 16 pixel versions of the each of the icons above, for themes
that do not require large print.
Install the icons to the image files location that is specified for the theme in
tion 10.3.2, "Installing a New Controls Option"

trastLargePrint theme, add the icons to the /opt/gnome/share/themes/
HighContrastLargePrint/pixmaps directory. Add references to the icons to
the relevant theme files. For example, to add icons to the HighContrastLargePrint theme,
add references to the icons to the /opt/gnome/share/themes/
HighContrastLargePrint/ gtk-2.0/gtkrc file. Modify the gtkrc file for
the theme to associate the icon with a GTK stock icon identifier.
