That depends entirely on what the ASCII file contains.
Is it a comma separated list of RGB values? Or is it
a uuencode of the binary data? Or something else...

Depending on the formatting you may not need PIL,
but it all depends on what the ASCII contains.

You may only need one of the encode/decode libraries
for something like uuencoding or maybe the struct module
will do if its just raw bitmap data.

Yes you can always do it manually but it all depends
on the format of the data.
