Posted from: 173.52.179.61 45868 1 graveltech 2011-02-19 19:17:46 +0000 My use case is a LOGO interpreter in Javascript that does the drawing on the canvas. I'm able to use transformations to draw the path of the turtle but if I draw the turtle then I need to clear the canvas before running the next command to avoid leaving a series of turtles. If I was able to load the transformation matrix I believe I could use it as a CSS transformation to position an image on top of the canvas. 45869 2 graveltech 2011-02-19 19:29:35 +0000 I guess I'm not the only one wondering this: http://lists.whatwg.org/htdig.cgi/whatwg-whatwg.org/2010-July/027394.html 48010 3 ian 2011-05-04 23:44:26 +0000 EDITOR'S RESPONSE: This is an Editor's Response to your comment.
