The Icon Editor
With the Icon Editor, you can change the appearance of icons that appear
on the Workbench. You can find the Icon Editor in the System drawer on
the Workbench.
To use the Icon Editor, you must be familiar with the Amiga Disk Operating
System (AmigaDOS) and the conventions it uses for file names. To learn
about AmigaDOS, see the
AmigaDOS Manual.
If you are a software developer, you can also use the Icon Editor to create
icons for new tools, projects, and drawers. To learn how to create new
icons, see the
Amiga ROM Kernel Manual.
Opening the Icon Editor
You open the Icon Editor by selecting its icon, then choosing Open from
the Workbench menu. When you do, a window for the Icon Editor
appears. Next, a requester appears in the window that describes the
different kinds of icons. Select the OK gadget to continue. (For
information about the different icon types, see the
Amiga ROM Kernel
Manual.)
