OS/2 Icon

OS/2 Icon is an icon format related to OS/2 BMP. It is a member of the OS/2 bitmap family of formats. It is very similar to OS/2 Pointer format. It is not particularly similar to Windows ICO format.

There is a color format, and a bi-level format. Multiple icons may be stored in the same file using the "bitmap array" ("BA") container format. The BA format may be used even when the file contains only one icon.

OS/2 icons are sometimes embedded as resources in OS/2 Linear Executable files.

Identification
An OS/2 Icon file may begin with ASCII characters "" (color), or "" (bi-level).

Or, it may begin with "", and have "" or "" at offset 14.
