For image types that do not support an alpha channel, the image must be
|
||
|
|
composited onto a solid black background using the source-over operator,
|
||
|
|
and the resulting image must be the one used to create the data: URL.

Author's note:
|
||
|
|
To add more cases to this test:
|
||
|
|
- To add a row (another color value)
|
||
|
|
* Add a row to the table below, using the canvas id format
|
||
|
|
(c<row>-<col>)
|
||
|
|
* Update runTests to include the new row in the loop
|
||
|
|
- To add a column (another image format)
|
||
|
|
* Add a column to the table below, using the canvas id format above
|
||
|
|
* Update runTests to call do_canvas, passing your column number,
|
||
|
|
the image format, and any options to pass to the toDataUrl function
