I don't figure why you can want transparency in a button ???

Lee Ambrosius

You use transparency for the pixels of your image that you don't want to contain any color. This is done so the color assigned in the Windows theme comes through and behaves just like the standard AutoCAD icons.

ok, much simpler:
start illustrator, photoshop, gimp or any other true graphic software. Remove background layer and save the file as a 24-bit 'png-file'. Possibly you can print a an Autocad-file to a png-file, but I didn't bother to try that. Then do as usual.
This technology is used in flash-animation, skinning of winamp and firefox for instance.

Lee Ambrosius

I do understand your process and use it all the time for many things. AutoCAD doesn't support the use of PNG files for toolbar bitmaps, only BMP, RLE or DIB files.
