Having been experimenting with compressing screens of pixels I was wondering if it were possible to write a compressor that returned the results of a dithered image. That is, where the output results would be difficult or impossible to compress effectively using standard methods of image compression.
And this is a 1st stage. Tomorrow if I have time I'll work on and post the 2nd stage. If it's successful it will also dither an image but in a third of the current compression space (less than 512-chars) yet still span the full screen.
For instance this particular image compresses from 16384-chars (raw image) to 1457-chars. Obviously it does not include all 16-colors and instead relies on a black and white table that is a size of 5. Five because I want to have both solid black and white in it.
Yet I think this is useful, especially if someone wants to include a large number of "clipart" images in their cart and for them to be dithered, perhaps for an adventure or mystery game that relies on many pictures.
