That seems impossible, and the way out is Tkinter. I'm not yet savvy enough with Pythons graphics. I was definitely leaning towards PhotoImage as the way out. What module is show in? Repairing my (0,0), ... to (0,0)+, and. replacing arg with ImageOPen, produces a correct solution. My NM Tech pdf misses the boat on PhotoImage. I've seen your reference before, but never looked at PhotoImage. I'll bookmark it. I sure wish it was in pdf format. Thanks. -- W. eWatson (121.015 Deg. W, 39.262 Deg.

Drawing and Displaying an Image with PIL
Here's my program: # fun and games import Image, ImageDraw im = Image.open(wagon.tif) # it exists in the same Win XP # folder as the program draw = ImageDraw.Draw(im) draw.line((0, 0) + im.size, fill=128) draw.line((0,0),(20,140), fill=128) # How show this final image on a display? root.mainloop() It has two problems. One is it crashes with: draw.line((0,0),(20,140), fill=128) TypeError: line() got multiple values for keyword argument 'fill' Secondly, it has no way to display the image drawn on. Is it possible, or do I have to pass the image off to another module's methods? -- W. eWatson (121.015 Deg. W, 39.262 Deg.

Here is an example from the docs Example Example: Draw a Grey Cross Over an Image import Image, ImageDraw im = Image.open(lena.pgm) draw = ImageDraw.Draw(im) draw.line((0, 0) + im.size, fill=128) draw.line((0, im.size[1], im.size[0], 0), fill=128) del draw # write to stdout im.save(sys.stdout, PNG) Hope that helps -- http://mail.python.org/mailman/listinfo/python-list

In fact, I borrowed it from the pdf. I just tried it, and it output %PNG. I'd like to see this displayed in a window. If the fine had written properly, I could see whether it really drew the lines. It did not fail on the same draw stmts in my program. I see my problem, , instead of + between the tuples. I thought I'd seen another example where the 2-d tuples could be separated. I see a ImageFile module, but it's not for writing image files simply. -- W. eWatson (121.015 Deg. W, 39.262 Deg.
