This directory contains tools for bitmap conversion.
This directory contains 8bitworkshop tools for bitmap and
music conversion.
Requires ImageMagick (convert) and Python 2.x.
MIDI tools require Mido (pip install mido).

On Ubuntu:
Converts a .jpg into a 40-pixel wide playfield bitmap.
Cut-and-paste output into program.
(See Chapter 20, Asynchronous Bitmaps)
$ sudo apt update
$ sudo apt install python python-pip imagemagick curl

To use the tools, go to the appropriate directory and
look at the Makefile for each:
Converts a .jpg into a 48-pixel wide sprite bitmap.
