PaintWeb in Internet Explorer

Hello world!

Three days ago we received great news from Microsoft: the third platform preview release of Internet Explorer 9 includes support for the Canvas 2D Context API. Canvas comes into IE 9 together with numerous other platform improvements.

These days I have been working on my open source project, PaintWeb. I am quite excited to see it running quite well in MSIE 9.

Go ahead and try the PaintWeb demo page in Internet Explorer 9!

What works? Almost everything. Known issues:

  • The globalCompositeOperation property is not yet supported by MSIE 9. The Color mixer visualization looks a bit weird because of this.
  • If you change the canvasElem.style.width/height properties the Canvas element is cleared. This is wrong and breaks the implementation of image load and zoom. Check a minimal test case.
  • The PaintWeb integration into TinyMCE demo page fails to work. It seems that TinyMCE 3.2.5 fails to work properly in MSIE 9. I shall upgrade it to the latest version, and thus update the PaintWeb plugin as well.

You may also check the PaintWeb change log, for more details.

Any feedback is welcome!
