after some digging, this appears to be a bug in how putdata behaves on
memory-mapped images. the simplest way to work around this is to do:
img = Image.open(bmp_file)
img = img.copy() # make sure we have a writable copy
if you want to be a bit more careful, you can do:
# make sure putdata can write to the image memory
img = img.copy()
hope this helps!
