Note that the Chrome nightly (r30453) on Windows currently does not show this problem. The WebKit nightly (r52593) on Windows does. Original report follows: --- Importing issue http://code.google.com/p/chromium/issues/detail?id=21847 Reported by btlee@google.com, Yesterday (36 hours ago) Chrome Version : 4.0.206.1 (Official Build 25376) URLs (if applicable) : http://members.shaw.ca/briantclee/canvas.html Other browsers tested: Add OK or FAIL after other browsers where you have tested this issue: Safari 4: FAIL. Firefox 3.x: OK Opera 10: OK IE 7: FAIL. Canvas not supported. IE 8: FAIL. Canvas not supported. What steps will reproduce the problem? 1. Have a webpage: 1. Create an Image from a data URL. 2. Create a canvas. 3. Draw the image to the canvas. 4. Call canvas.toDataURL(). 2. Launch the webpage. What is the expected result? toDataURL() returns a data URL for the image drawn to the canvas. What happens instead? Error in the console: "Uncaught Error: SECURITY_ERR: DOM Exception 18". Drawing from an image with source being a data URL seems to set the origin-clean flag false. I don't think this should be although it doesn't explicitly mention this in http://www.whatwg.org/specs/web-apps/current-work/multipage/the-canvas-element.html 205514 1 abarth 2010-03-29 10:27:37 -0700 Comment 5 by abarth@chromium.org, Sep 19, 2009 Fixed in http://trac.webkit.org/changeset/48556 Status: Fixed
