It would be interesting if you could provide one of those PS files produced with IDL, such that we can see if there some tricky PostScript code that we could implement in the PS driver. At any rate, I can hardly imagine how the situation can be improved. The Plplot function plcont generates a series of colored patches which are translated into filled polylines by the PS driver. Adjacent patches are perfectly juxtaposed, meaning that the coordinates in their common borders coincide. I generated a example PostScript file (attached below) with two red squares in a white background that must look like a rectangle. However, when viewing this simple file with gv and antialising activated, I see a white line between the two squares. -- Rafael |
