The black diagonal lines show in all output formats, so the problem is in the splash rasterization and not in the final image file generation. The lines seem to be one pixel in the image, no matter what I use as the resolution, so maybe a fill or crop calculation is not symmetrical and two adjacent regions end up with an unfilled gap between them. xpdf-3.04 works correctly, but the splash code has diverged enough that it is hard to compare. vectorAntialias is used mostly in Splash.cc. This PDF uses Splash::blitImageClipped, Splash::fillWithPattern and Splash::gouraudTriangleShadedFill.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
