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?
