@Chris Wilson et all: I'd like to raise priority on this issue. We know the issue to exist for several years now on Linux systems. Recently we see more and more Windows systems to suffer from the same issue. The attached patch is simple and fixes the issue. Is there anything I can do to summon a cairo maintainer here? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to cairo in Ubuntu. https://bugs.launchpad.net/bugs/1306846 Title: Inkscape (using cairo) fails to print thin lines to PDF Status in libcairo - cairo vector graphics library: Confirmed Status in cairo package in Ubuntu: Triaged Bug description: Since 1.12.3, cairo cannot render fine lines to pdf. 1.12.2 was the last version that worked. http://cgit.freedesktop.org/cair/diff/?id=bdf83008f4b2c723fd8e65e2a92bc47a2e7bc442 introduced code to avoid lines that would be invisible when rasterized. While this is a valid logic for raster backends, it is a bad idea for PDF output. There we want to see all fine lines. My specific use case is generating a lasercutter drawing for an Epilog Zing laser with inkscape. There the hardware would raster anything thicker than 0.02mm, and cut 0.01mm or below. 1.12.3 skips lines below 0.036mm, 1.13.1 skips lines below 0.018mm -- which is still not enough to safely drive my lasercutter. Previously reported against inkscape: https://bugs.launchpad.net/inkscape/+bug/1174909 Also reported agains cairo upstream with a suggested fix: https://bugs.freedesktop.org/show_bug.cgi?id=77298 Check out the attached reproducer and fix. I'd suggest to circulate patched ubuntu packages, until upstream releases an official fix.
