Description
In the provided PDF file, there is a block that is overlaid over some text in the rendered PDF. This block is related to an empty textbox.
Traced out the logic for colour key masking and it appeared like everything was in order. The only short cumming as was the buffer didn't actually have an alpha channel.
Added a check for alpha and if not present will copy the the image mask data to 4 component types. This allows the alpha to be painted correctly.
