thanks for reply, Matthias,
when I use "show()", the image appears to have an all-white
background, nothing else is on it. The size does indeed match the png
size , I used the following to confirm:
x, y = outIm.size
print "size of outImg: " + str(x)+" " + str(y);
I tries to resave the png as a png image with a different name using
PIL and show() of the 2nd png image still appear to have all-white
background with nothing on it.
but If I open the images (both the 1st and the re-saved image ) with
the command line command of "display", I can see the images via
Attached is example image which I am having problem with. Can you
reproduce the same problem I'm seeing with this image, possibly due to
the png image being broken?
