There's this code :

        if width is None:
            width = imgObj.width
        if height is None:    
            height = imgObj.height
in canvas.py's drawImage() method.

maybe doing this instead (untested) would fix the problem :

        if not width :
            width = imgObj.width
        if not height :    
            height = imgObj.height
I'm now struggling with masks to render parts of images transparent, 
this used to work but doesn't seem to work anymore. To my knowledge 
the only thing I changed was Acroread (from 5.x to 7.0)... 

Also I've just seen in Acrobat Reader's preferences that PDF files
with layers exist. Is there an API in ReportLab to create multilayered
PDF documents ?

Thx for your time
