Why does PIL fail to merge 2 images in my code?

Solution
There are two possible issues.
Are you sure your 4-tuple `(0, height, width, textHeight)` is correct? It should be `(left, upper, right, lower)` pixel coordinates. In this case the pasted image must match the size of the region, and I think this is where your error lies. Alternatively you can give a 2-tuple giving just the upper left corner of where you want to paste the picture. See: http://effbot.org/imagingbook/image.htm
Are you sure that height, width, textHeight are `ints` and not `floats`?
You could try something like this:
x, y = img1.size
wrapper.paste(textImage,(0,height,x,y))
Problem
I am trying to combine 2 images into a larger one with Image.paste function. I start by creating an image that can hold both images, and then paste in the 2 images: ``` wrapper = Image.new("I", (width, height+textHeight)); if placement=="bottom": wrapper.paste(img1); wrapper.paste(textImage, (0, height, width, textHeight)); else: wrapper.paste(textImage); wrapper.paste(img1, (0,textHeight)); ``` Then I get this error every time: ``` File "C:\Python27\lib\site-packages\PIL\Image.py", line 1127, in paste self.im.paste(im, box) ValueError: images do not match ``` I am very sure that the sizes of the images are correct, and the wrapper image can hold both images. The only way to avoid this error is to make the 3 images (wrapper and 2 components) same size, and paste from (0,0). I am at my wits' end, please help!
