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.
