http://www.w3.org/Bugs/Public/show_bug.cgi?id=12705 --- Comment #10 from Aryeh Gregor <Simetrical+w3cbug@gmail.com> 2011-05-22 22:38:28 UTC --- Your "almost singular" matrix isn't very close to singular at all. It has a determinant of .00002. That's quite a lot, since your lineWidth is 1999999. Try something like this instead: http://software.hixie.ch/utilities/js/live-dom-viewer/saved/1002 If I set e to 0.0000001, Firefox draws the red square successfully. If I add one more zero, so it's 0.00000001, Firefox doesn't draw anything, even though w(1 - e == 1) logs "false". WebKit seems to have the same magic threshold, after which it just ignores the operation (even though the width variable is large enough that it should really draw the big black line). So it doesn't seem to be just testing whether it's actually singular, it looks like they're testing that it's just "close" to singular. -- Configure bugmail: http://www.w3.org/Bugs/Public/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug.
