Rik, I read through the whole thread again and realized I've caused some redundancy by asking questions that were already answered. Apologies for that. I understand the reason for the check for non-revertible matrices, and should have seen that example mentioned earlier, as it would have prevented me from drawing false conclusions.
But just to clarify: What you wrote on November 2nd is not how the browsers currently behave: On Nov 2, 2013, at 01:01 , Rik Cabanier <[email protected]> wrote: > var ctx = ...getContext("2d"); > > ctx.scale(2, 2); > > ctx.moveTo(10, 10); > > ctx.lineTo(100, 10); > > var p = ctx.currentPath; > > Path p would contain a line from (20, 20) to (200, 20) If I test this, store the currentPath, then reset the CTM, and then use the path to draw, I can confirm that it is drawn in the coordinates specified in code, and does not backe the current CTM in: ctx.beginPath(); ctx.scale(2, 2); ctx.moveTo(10, 10); ctx.lineTo(100, 10); var p = ctx.currentPath; ctx.setTransform(1, 0, 0, 1, 0, 0); ctx.currentPath = p; ctx.strokeStyle = '#000'; ctx.lineWidth = 1; ctx.stroke(); So Path p contains a line from (10, 10) to (100, 10)
