If I remember correctly, around 1996 a demonstration PostScript viewer with high-quality filtering was making the rounds on the net. The results were pretty impressive to me at the time. Allegedly the three key ingredients were wide filter support, negative sidelobes in the filter kernel, and deconvolution to account for CRT spot intensity effects. Wish I could find a reference to it. Allen _______________________________________________ Render mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/render
