Open BMP files FOR BINARY. You have to get information from the bitmap header to find the BPP, offset, dimensions in the first 54 bytes.

The color settings and image are read with GET one byte at a time.

Use Paint and create bitmap fonts from Windows of 1 BPP (white on black background).

Look in the downloads section here.

Or look at www.QbasicStation.com

Look in member Files there. I have several BMP programs there.

To do fonts easily, dump an ascii table from a DOS window with the font set to what you want.

Then screen capture it, convert it to a BMP, then use the BMP decoding code to save the font data as bit patterns.

If you want to work with *.BMP's, I recommend only working with 24-bit BMP's.

There is a site that I know of that has all you need to work with *.BMP's.

Lookie thar.. and you shall find.

My favorite fonts are 4x6, 8x8, and 8x16.
