I am looking for a good set of bitmaps I can use on a monochrome X-server to emulate gray shades. I already have a good set of 10 different shades but I really need a larger set, perhaps 32 to 64 shades. Let me know if there is a place I can anonymous ftp these from or just mail me your best set. Any kind of help is appreciated. Send mail to: ballard@mc1.wes.army.mil or h4enajb0@larry.wes.army.mil Thanks, -Jerry -------------------------------------------------------------------- Waterways Experiment Station | Internet: ballard@mc1.wes.army.mil ATTN: EN-A, Jerrell R.

Well, you can only get so precise with your shades. The more shades you get, the bigger the pixmaps have to be and the farther you have to be from your screen. You could use the Floyd-Steinberg algorithm to generate your shades. Look at xloadimage for details. i.e. Use a pixmap (say 64x64) and modify the Floyd-Steinberg algorithm to try applying a single gray level value to each pixel. You will get very pleasing results since the F&S algorithm will minimize the contact between black values in your shade. -- Eric Taylor Baylor College of Medicine etaylor@wilkins.bcm.tmc.edu (713) 798-3776
