50313 2010-11-30 23:04:27 -0800 [Gtk] Text height in zoomed SVG is 1px too high 2011-02-01 04:02:49 -0800 1 1 1 Unclassified WebKit SVG 528+ (Nightly build) PC Linux RESOLVED DUPLICATE 12448 P2 Normal --- 50314 0 ctruta webkit-unassigned mdelaney7 mrobinson zimmermann oldest_to_newest 315548 0 ctruta 2010-11-30 23:04:27 -0800 In the following test cases: css3/zoom-coords.xhtml svg/zoom/page/zoom-zoom-coords.xhtml the text height is one pixel too high. The text height is set to 12px (using the Ahem font), and showed in scaled coordinates. For example, when the scale is 50%, the expected text height is 6. These test cases pass on all platforms except for GTK. On GTK, the function getBoundingClientRect indicates the text height to be 6.5 instead of 6, and 13 instead of 12. 315553 1 ctruta 2010-11-30 23:29:26 -0800 For the time being, the two failing tests are listed in platform/gtk/Skipped This is done in bug 50314. The patch for 50314 should be undone when this bug is fixed. 315567 2 mrobinson 2010-12-01 01:05:19 -0800 Thanks for opening this bug. Does this only affect GTK+? 315660 3 ctruta 2010-12-01 08:29:53 -0800 (In reply to comment #2) > Thanks for opening this bug. Does this only affect GTK+? I assume that's the case, because I did not see other failures elsewhere. The platforms where I run tests myself are webkit-mac and chromium-linux. 315685 4 75279 ctruta 2010-12-01 09:19:30 -0800 Created attachment 75279 Reduced test case Actually, it's not even necessary to use the CSS3 zoom attribute to reproduce the failure. The first SVG test ("svg1") in css3/zoom-coords.xhtml is only scaled using ... height="50px" viewBox="0 0 150 100" and it's still failing. It may be possible that it isn't even a zooming issue, after all. I wonder, is the attached test ("text-height.xhtml") passing under GTK? 343121 5 zimmermann 2011-02-01 04:02:49 -0800 The patch on bug 12448 fixes this problem. *** This bug has been marked as a duplicate of bug 12448 *** 75279 2010-12-01 09:19:30 -0800 2010-12-01 09:19:30 -0800 Reduced test case text-height.xhtml application/xhtml+xml 1130 ctruta PGh0bWwgeG1sbnM9Imh0dHA6Ly93d3cudzMub3JnLzE5OTkveGh0bWwiIHhtbG5zOnhsaW5rPSJo dHRwOi8vd3d3LnczLm9yZy8xOTk5L3hsaW5rIj4KPGhlYWQ+CjxsaW5rIHJlbD0ic3R5bGVzaGVl dCIgaHJlZj0iLi4vZmFzdC9qcy9yZXNvdXJjZXMvanMtdGVzdC1zdHlsZS5jc3MiLz4KPHN0eWxl IHR5cGU9InRleHQvY3NzIj4KICAgICN0ZXh0SW5IVE1MLCAjdGV4dEluU1ZHIHsgZm9udDogMTJw eCBBaGVtOyB9Cjwvc3R5bGU+CjwvaGVhZD4KPGJvZHk+Cgo8c3BhbiBpZD0idGV4dEluSFRNTCI+ VGV4dCBpbiBIVE1MPC9zcGFuPgo8c3ZnIHdpZHRoPSIxMDAiIGhlaWdodD0iNTAiPgogICAgPHRl eHQgaWQ9InRleHRJblNWRyIgeD0iMjAiIHk9IjIwIj5UZXh0IGluIFNWRzwvdGV4dD4KPC9zdmc+ Cgo8ZGl2IGlkPSJkZXNjcmlwdGlvbiI+PC9kaXY+CjxkaXYgaWQ9ImNvbnNvbGUiPjwvZGl2PgoK PHNjcmlwdCBzcmM9Ii4uL2Zhc3QvanMvcmVzb3VyY2VzL2pzLXRlc3QtcHJlLmpzIj48L3Njcmlw dD4KPHNjcmlwdD4KCmZ1bmN0aW9uIG1zZ0R1bXBSZW5kZXJUcmVlUmVxdWlyZWQoKQp7CiAgICBp ZiAoIXdpbmRvdy5sYXlvdXRUZXN0Q29udHJvbGxlcikKICAgICAgICBkZWJ1ZygiVGhlIGZvbGxv d2luZyB0ZXN0cyBtYXkgZmFpbCBpZiBub3QgcnVuIGluIER1bXBSZW5kZXJUcmVlOiIpOwp9Cgpk ZXNjcmlwdGlvbigiQ2hlY2tpbmcgaGVpZ2h0IG9mIHRleHQgaW4gMTJweCBBaGVtIGZvbnQiKTsK Cm1zZ0R1bXBSZW5kZXJUcmVlUmVxdWlyZWQoKTsKdmFyIHRleHRJbkhUTUwgPSBkb2N1bWVudC5n ZXRFbGVtZW50QnlJZCgidGV4dEluSFRNTCIpLmdldEJvdW5kaW5nQ2xpZW50UmVjdCgpOwpzaG91 bGRCZSgndGV4dEluSFRNTC5oZWlnaHQnLCAnMTInKTsKdmFyIHRleHRJblNWRyA9IGRvY3VtZW50 LmdldEVsZW1lbnRCeUlkKCJ0ZXh0SW5TVkciKS5nZXRCb3VuZGluZ0NsaWVudFJlY3QoKTsKc2hv dWxkQmUoJ3RleHRJblNWRy5oZWlnaHQnLCAnMTInKTsKZGVidWcoIiIpOwoKc3VjY2Vzc2Z1bGx5 UGFyc2VkID0gdHJ1ZTsKCjwvc2NyaXB0Pgo8c2NyaXB0IHNyYz0iLi4vZmFzdC9qcy9yZXNvdXJj ZXMvanMtdGVzdC1wb3N0LmpzIj48L3NjcmlwdD4KCjwvYm9keT4KPC9odG1sPgo=
