BioStatMatt (shotwelm) wrote : evince automatically interpolates embedded PostScript images

Binary package hint: evince

In the following Postscript code, an image should be displayed without interpolation (smoothing). GhostScript and KGhostView, and others correctly interpret this code. However, evince interpolates the image automatically without regard to the explicit instruction ( /Interpolate false ) not to. Can anybody explain why this is the case, and if it can be fixed?
