Here's a tool to create 2-bit bitmaps (4 colors) for the Propeller. Screenshots:     Use this program to create a data file that can be included in your SPIN code. You pick 4 colors from the image and the program finds the best match for every pixel. Download the Windows app here.

I've also made TV and VGA test apps for these bitmaps that shows how to use them: Cycles between a full-screen image and an image composed of 3 individual bitmaps. TV Screenshots:     These screenshots are in interlaced mode, but non-interlaced mode is better for this little LCD screen.  You can change 2 numbers in the DAT section (as indicated in the file) to get non-interlaced mode. Download the Prop TV test app here.   Download the Prop VGA test app here.
