this doesn't seem sensible to me at all. after using numeric arrays to =
do the "some_function", im.putdata(numeric_array.flat) would surely be=20
better, as seen in my earlier post.
nested for loops and individual putpixel's at the python level would be =
much slower than taking advantage of something like putdata which=20
implements the for loop at the C level. yeah?
