Works with cairo 1.12.2. Fails with cairo master. I get the same problem with SVG output. Works in 1.12.2, fails with master. This points to a bug in the recording surface. Does it mean the bug needs to be filed elsewhere, or is it Cairo issue? It is a cairo bug. Likely a dupe of bug #73038 |

Created attachment 92547 [details] transparent.pdf There is a semi-transparent image in the attached PDF "transparent.pdf". When converted with pdftocairo 0.24.5 based on cairo 1.12.16 with all the recent patches from master branch, pdftocairo -ps -level3 transparent.pdf transparent-cairo.ps, we get unexpected black background on that image. When converted with pdftops 0.24.5, pdftops -level3 transparent.pdf transparent-ps.ps, background is rendered properly, white. transparent.pdf, transparent-cairo.ps, and transparent-ps.ps are attached.
