I've been using your print_eps function for a while and found this today. However, I have a problem with converting images to eps format that has been bugging me. For example, I have two images in a matlab figure. On both images I have used the "plot" function to plot some lines on the images. The plotted lines are gray in color. When I export them into eps format, the lines on the first image would remain gray. But the lines on the second image would change to black. The same thing happens when I have more than two images with plotted lines, in which case all the plotted lines except in the first image will turn black. I was wondering if you can shed some light on this?
