Hi John, Yes, it does compression. Runs of pixels that are the same color (either on or off) are compressed into either one, two or three bytes depending on the length of the run.
I did some tests taking a PBM binary file compressed with WinZip and compared it with the compression in AP. In some cases, AP is actually better (small images ... no dictionary needed). On larger images, WinZip was only 7-8% better on average. Ken On Mon, Apr 24, 2017 at 9:08 AM, John R. Hogerhuis <[email protected]> wrote: > Very nice! > > Does AP do any compression?
