Tilman Hausherr resolved PDFBOX-2153. ------------------------------------- Resolution: Fixed Fix Version/s: 2.0.0 1.8.7 Assignee: Tilman Hausherr > Setting the correct clipping path for shading > --------------------------------------------- > > Key: PDFBOX-2153 > URL: https://issues.apache.org/jira/browse/PDFBOX-2153 > Project: PDFBox > Issue Type: Bug > Components: Rendering > Affects Versions: 1.8.5, 1.8.6, 1.8.7, 2.0.0 > Reporter: Tilman Hausherr > Assignee: Tilman Hausherr > Labels: shading, shadingpattern > Fix For: 1.8.7, 2.0.0 > > > While doing tests with the file eci_altona-test-suite-v2_technical_H.pdf > (uncompressed) of PDFBOX-1915 I noticed that by removing a "W" (modifies the > clipping region) operator of a type 7 shading I got a lot more correct > shadings (type 6 and lower). It looked like PDFBox had been using the > clipping of the type 7 when drawing the type 6, which is just a rectangle > above in that rendering. This resulted in a blank. > By adding > {code} > graphics.setClip(getGraphicsState().getCurrentClippingPath()); > {code} > in PageDrawer.shfill() just before the graphics.fill() I get several files to > render correctly that I hadn't before. > (Setting null will probably do the same, didn't test that yet). > The following PDFs are rendered correctly with the change: > McAfee-ShadingType7.pdf > eci_altona-test-suite-v2_technical_H.pdf > crestron-p9.pdf (these three found in PDFBOX-1915) > PDFBOX-1451.pdf ("alfresco") > PDFBOX-1940.pdf ("chart") > PDFBOX-1861-tracemonkey.pdf p.11 > Not solved by the change: > PDFBOX-2098-asyTUG.pdf p.6 (this one doesn't use shfill) > PDFBOX-1861-tracemonkey.pdf p.6 (not shading) > PDFBOX-1416.pdf (not shading) > texample-rgb-triangle.pdf (John has an explanation about that one) > WDYT? Is there any reason NOT to set the clipping path in PageDrawer.shFill() > ? -- This message was sent by Atlassian JIRA (v6.2#6252)
