python - ReportLab - Can't mask image [Google App Engine] -


i generating pdf using reportlab, on google app engine.

i can draw images in pdf, cannot mask applied.

here's code drawing simple green-masked circle (and circle):

# draw circle mask on profile image path = os.path.abspath(os.path.join('pdf_profile_mask.jpg')) c.drawimage(path, 62, 62, 126, 126, mask=[0,255,200,255,0,255])

green-circle mask image

it didn't work, tried masking colors (i expect nothing drawn):

c.drawimage(path, 62, 62, 126, 126, mask=[0,255,0,255,0,255])

but didn't work either - image solid.

reportlab doesn't support images out of box on appengine - changes make run minor , don't think should affect this.

does have experience this?

it wouldn't work me either jpg image. converting png did trick.
