The code for the pildriver.py "paste" operation currently looks like this:
def do_paste(self):
"""usage: paste <image:figure> <int:xoffset> <int:yoffset>
<image:ground>
Paste figure image into ground with upper left at given offsets.
"""
figure = self.do_pop()
xoff = int(self.do_pop())
yoff = int(self.do_pop())
ground = self.do_pop()
if figure.mode == "RGBA":
self.push(ground.paste(figure, (xoff, yoff), figure))
else:
self.push(ground.paste(figure, (xoff, yoff)))
This seems somewhat useless -- a None value gets pushed on the stack.
More useful would be:
def do_paste(self):
"""usage: paste <image:figure> <int:xoffset> <int:yoffset>
<image:ground>
Paste figure image into ground with upper left at given offsets.
"""
figure = self.do_pop()
xoff = int(self.do_pop())
yoff = int(self.do_pop())
ground = self.do_pop()
if figure.mode == "RGBA":
ground.paste(figure, (xoff, yoff), figure)
else:
ground.paste(figure, (xoff, yoff))
self.push(ground)
Otherwise you need an extraneous dup (to make a copy of the ground)
and pop (to get rid of the None) in there.
