2009-11-30 Dirk Schulze <krit@webkit.org> Reviewed by Nikolas Zimmermann. Complex test of mask with every combination of maskUnits and maskContentUnits as well as different values for size and position of the mask and it's content. * platform/mac/svg/custom/mask-with-all-units-expected.checksum: Added. * platform/mac/svg/custom/mask-with-all-units-expected.png: Added. * platform/mac/svg/custom/mask-with-all-units-expected.txt: Added. * svg/custom/mask-with-all-units.svg: Added. 2009-11-30 Dirk Schulze <krit@webkit.org> Reviewed by Nikolas Zimmermann. REGRESSION (r49757): masking-mask-01-b.svg rendered incorrectly [https://bugs.webkit.org/show_bug.cgi?id=31980] It turns out, that we did not handle maskUnits="userSpaceOnUse" correctly. We just need to move the context of the maskImage if maskContentUnits="objectBoundingBox". The context gets scaled on this unit combination, so we have to substract the position of the targetRect. On userSpaceOnUse the position just depends on the position of the mask element. I added a test with some senseless and reasonable values for size and postion of the mask and it's contents. I also used every combination of maskUnits and maskContentUnits to be sure, that it is fixed this time.
