About
=====

bmp2bin as a command-line tool for converting 32-bit
BMP files to 15/16/32-bit binary files.

BMP files need to be 32-bit and have a v5 header. Tested
and works using Pixelmator Pro saved files on macOS and
I think GIMP works to.

This tool was made when I wanted to try to do a system
friendly AmigaOS RTG game using Picasso96 (P96)/CyberGraphX
and found no way on the Amiga to do graphics higher
then 8-bit. As an old school bare-metal developer I like
to open or incbin my bin/raw files.
