When you install a new icon for an application, 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 Oracle Solaris 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 × 48 pixels. At this size, most themes can rescale the icons.
When you install a new icon, create the following 48 × 48 pixel versions of the icon:
Regular icon
High contrast icon
Inverse high contrast icon
If possible, you should also create 16 × 16 pixel versions of each of the listed icons for themes that do not require large print.
The Oracle Solaris 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.
