I am trying to add a set of nice icons to my custom (plugin-based) Acrobat toolbar. The issues are those to be expected:

– What dimensions are acceptable?
– What color depth?
– What graphic file format?
– How do I handle transparency?

As a newbie, I just discovered that bitmaps (*.bmp) don’t seem to support 32 bit color (or transparency?)

My target is Windows XP, which apparently supports 32 bit color.

What I currently have is 24x24x24 bitmaps, but the background shows as white.

TIA,

-Ramon

The BMP format does indeed support 32-bit (RGBA) color. There may be individual applications that don’t read 32-bit BMPs, but it’s easily supported by the form of the file. I’m not sure if there’s an official spec anywhere, but Photoshop and Microangelo (and likely others) support those types of BMPs.

The ICO file format is close to the BMP format, but with a mechanism for storing multiple icons (bitmaps) and their masks in a given file. This enables you to define various sizes of the same icon so the consumer of the file can pick out what it needs.
