After further testing I realized that these "grey" lines only appear when I don't set the the background color of the pixmap. If I do fz_clear_pixmap_with_color(pix, 255); then no lines and pages look perfect. If I do fz_clear_pixmap(pix); in order to preserve alpha I get the "grey lines" P+ That's anti-aliasing at work. Turn off "Enhance thin lines" in Adobe Reader and you also get gray lines. Rendering with a transparent background makes these problems more visible. They're still there with a white background, just less obvious. *** This bug has been marked as a duplicate of bug 691930 *** |
Created attachment 7762 [details] Too many gray lines The attatched PDF when displayed renders many gray lines. These lines do not show up in Acrobat reader. When I change the anti-alias level to 0 less lines are displayed, but when set to 8 an excessive amount of gray lines appear. Side note: These gray lines do not appear is SumatraPDF 1.7. Thanks, Pedro
