the three first sections in the PIL handbook discusses how to create,
load, save, and cut/paste images.
here's an outline:
import Image
out = Image.new("RGB", (2048, 2048), "white")
for line in open("myfile.txt"):
x, y, name, pngfile = line.split()
out.paste(Image.open(pngfile), (int(x), int(y)))
out.save("out.png")
this assumes that the text file is named "myfile.txt", and contains white-
space separated items.
if you're new to both tools, skimming the tutorials before you start tinkering
will most likely save you some time later on:
