Hello, I have a customer that is asking me about this. They are very interested in the capability that is in 5.3 to do this (unfortunatly it still doesn't work even under 5.3-1) However, their question is once it does work is there any way to play with the output color map. For example when the output file is generated they would like some way to say if the screen background was gray then print it as white etc. The uses for this should be fairly obvious since as you are now printing in color if the background of a screen you are coping is in color it would presumably try to reproduce it accuratly and this would be a waste of time. Any ideas, Peter

From what I have seen of the color sixel protocol there is no way to do this. Sixels have no notion of color maps, each sixel has a hardcoded color. kathy | |||||

Re: .1 I'm not sure why you'd say that, Kathy. Sixel files do use color map entries (the equivalent of PseudoColor). All the customer would have to do would be to capture the print screen output into a file and edit the file. The color definitions are in the form: # Pc ; Pu ; Px ; Py ; Pz where: Pc is the color index (0 to 255 on the LJ250, although this may depend on whether it's in high or low density mode). Pu is the color coordinate system (1 = HLS, 2 = RGB) Px is the hue angle (0 to 360 degrees) in HLS or the red intensity (0 to 100) in RGB Py is the lightness (0 to 100) in HLS or the green intensity in RGB Pz is the saturation (0 to 100) in HLS or the blue intensity in RGB For example, medium blue as color 1 would be #1;1;0;50;100 in HLS or #1;2;0;0;100 in RGB. -- Bob |
