canvas.toDataURL() spec says implementations must support type "image/png" and may support other formats. We should probably support jpeg as well. However. we should not skip a test for required functionality because we don't support some additional functionality: I'm going to add expected results for the relevant tests (fast/canvas/toDataURL-supportedTypes.html, fast/canvas/canvas-toDataURL-case-insensitive-mimetype.html) for efl -- filing this bug so the jpeg support is not totally forgotten.
Closing this bug because the EFL port has been removed from trunk. If you feel this bug applies to a different upstream WebKit port and was closed in error, please either update the title and reopen the bug, or leave a comment to request this.
