We are often faced with the problem of transmitting large image matrices to a postscript printer, e.g. sampled images or screen captures from X. This causes large transmission times and we are thinking about compressing the binary data before transmission. Together with the data, a postscript decompression program is also send to the printer. The printer applies the program to the data and kind of unfolds the original image matrix. Before we start writing anything, has anybody ever done something like that? Especially is there a postscript program to decode fax Group3 encoded bitmaps? Any hints are greatly appreciated. Heinz W.
