ppmtovtx converts PPM format pictures (you can convert most formats to PPM with the NetPBM package) to Videotex/teletext format block graphics.

ppmtovtx can be downloaded with source code (in ANSI C) and ready-compiled binaries for Amiga (68k and OS4 PPC), DOS/Windows and intent, from the following sites:

• Further Information / Zip format archive (HTTP)
• LhA format archive (HTTP)

It should compile with no modifications on other operating systems, eg. Linux or MacOS.

The image on the right is an example of the output from ppmtovtx. This is a conversion of a scene from Knife & Wife, the original image can be found at Bubblegun.
