Create Icons from Bitmap Files

Create Icons from Bitmap Files

The following code generates standard icon files from Bitmaps.

Note: To create standard icons, compatible with any graphics applications, first, you may scale your Bitmap files into a size of (x*32)*(x*32); e.g., 32*32, 64*64, 96*96, 128*128* ...
