Hi guys,
Just poking through my old projects and I found zpic83 - an image compressor with an on-calc decompressor.
I never developed it to the point I would have liked but I thought, why keep it to myself?
The file can be downloaded here.
zpic83.exe can also be used to generate uncompressed images and is more forgiving than pic83 with regards to the image format (IIRC: pic83 required 1-bit PCX file... zpic83 doesn't care about colour depth).
It can take images of any size, but the decompressor will just output a flat stream of data, so it's only really useful for full-screen pics.
I actually wrote an on-calc compressor, which I still have, but it still needed a bit of work. Maybe once I've got the 3D engine out of the way I will take another look at it.

I originally wanted to write a compression program for the calc. I actually made some "concept graphics" outlining how the screen would look, etc.tr1p1ea wrote:Nice, i believe coelurus used LZ77 compression for his maps in Gemini.
Had you planned on making a game or something that would make use of this? Or did you just intend on releasing it as a util?
Another option I had considered was making self-extracting programs. It would be great for archive memory - store the program compressed, then decompress to RAM to run it. Although it screws program write-back if you want to use it.
