https://www.w3.org/Bugs/Public/show_bug.cgi?id=15937 --- Comment #5 from Aryeh Gregor <ayg@aryeh.name> 2012-04-29 06:45:04 UTC --- The units for matrix() and matrix3d() aren't all pixels. For matrix(), the first four entries are unitless and the last two are in pixels. For matrix3d(), entries 0-2, 4-6, 8-10, and 15 (0-indexed) are unitless; entries 12-14 have units of pixels; and entries 3, 7, and 11 have units of 1/pixels. I.e., [ # # # px] [ # # # px] [ # # # px] [1/px 1/px 1/px # ] where # is a unitless number. I don't think we need to say this explicitly. Instead, we should say how the matrices are used to transform coordinates, and make it clear that the input and output coordinates are in pixels. The units of the matrix entries will follow from that without having to introduce confusing and unhelpful stuff like 1/px explicitly. -- Configure bugmail: https://www.w3.org/Bugs/Public/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug.
