https://www.w3.org/Bugs/Public/show_bug.cgi?id=16406 --- Comment #1 from Dirk Schulze <dschulze@adobe.com> 2012-04-26 04:31:58 UTC --- I suggest the following wording: "" <h2 id="#two-dimensional-subset">Two Dimensional Subset</h2> <p> UAs might just support two-dimensional transformations as subset of this specification. In this case <a href="#three-d-transform-functions">three-dimensional transforms</a> must not be supported. The properties 'transform-style', 'perspective', 'perspective-origin' and 'backface-visibility' don't contribute to the rendering and must be ignored. The section about <a href="#transform-3d-rendering">3D Transform Rendering</a> does not apply. Matrix decomposing uses the technique taken from the "unmatrix" method in "Graphics Gems II, edited by Jim Arvo", simplified for the 2D case. The section about <a href="#mathematical-description">Mathematical Description of Transform Functions</a> is still effective but can be reduced by using a 3x3 transformation matrix where <em>a</em> equals <em>m11</em>, <em>b</em> equals <em>m12</em>, <em>c</em> equals <em>m21</em>, <em>d</em> equals <em>m22</em>, <em>e</em> equals <em>m41</em> and <em>f</em> equals <em>m42</em> (see <a href="#MatrixDefined">A 2D 3x2 matrix with six parameter</a>). </p> <img src="3x3matrix.png" alt="3x3 matrix" title="\begin{bmatrix} a & c & e \\ b & d & f \\ 0 & 0 & 1 \end{bmatrix}" width="82" height="79"> "" Any thoughts? -- 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.
