PNG to BMP with transparency preserved

[Sheff]

An animated bmp really isn't animated in and of itself. The format of the bmp is like a vertical filmstrip with each frame below the one before it and the program cycles through the images. I remember once I had to make one for a custom browser. It replaced the animated Internet Explorer "e" in the upper right corner of the browser.

Netscape 4.7 has it but the newer versions of explorer don't anymore.

It might be possible under program control.

For instance you can create a 32 x 32 pixel BMP based on the default 16 colour system palette.

Rename the extension to .ICO and use it as a desktop icon for shortcuts.

The pixel colour in the top left hand corner determines the transparency colour.

Such display control may be available as an MFC library call for BMP graphics.

But as I said, this is a software function and not inherently supported in the BMP format.

In fact, I did find a way to make the bmp white areas disappear finally, when imported into the utility by filling in black.
