I could not get transparency to work in reportlab 1.19, but it works
fine with 1.20.
This is an example:

white_is_transparent = [254,255, 254,255, 254,255]
canvas.drawImage("backgroundimage.gif", 0, 0, WIDTH, HEIGHT)
canvas.drawImage("foregroundimage.gif", 0, 0, WIDTH, HEIGHT,
white_is_transparent)

(draws the foregroundimage over the background image; the white
color is transparent).
