>I'm no expert but it is easy to see there are a few "issues" with image handling in VFP! I don't want to make a big project out of this but it's annoying to have the white aura on the command buttons when it doesn't appear on forms. I'm not really interested in converting the library I bought and I don't have much to work with except MS Paint anyway.

My choices are: 24-bit mask bmp, 32-bit alpha bmp, 32-bit alpha png, 32-bit icon, 256 color gif with transparency, 256 color png with transparency, 256 color icon, and the layered Adobe PSD file. Since I don't have PhotoShop, the PSD isn't much help. What would work best?

Linda, the best choice is to have 24-bit bmp files with white as a transparent color. You will not have that in your library for shure.

Second choice would be 24-bit bmp file with 1 bit msk file where white is transparent and black is opaque. You can open msk files with paint, a msk file is just a bmp file with the extension changed.

Since I plan on writing a couple of articles on this issue, if you want, you can send me some of files in each of the formats you have, and I could write a prg to easily convert those files to a VFP -friendly format.

This way I get a chance to experiment with this, and you get a chance to solve your problem. And we will both be helping other developers, since this is a common problem with VFP developers and image librares due to the non standard behaviour of VFP.
