Python Imaging Library and PyGTK - color image path?
I have an image in the Python Image Library. I'm trying to get it into PyGTK in color. Is there any way to do this cross-platform, preferably without writing to anything to the disk? PIL apparently can't write XPMs. GTK will only take XPMs, that I can see. Therein lies the rub. I can ship over monochrome bitmaps via XBM, but I'd rather be able to ship over full color. (Use case, in case it matters: I am trying to embed a graphic into a text widget. This is going fine. Because I want the text widget to be able use different size text, and no one image can look right with everything from 8pt to 40pt text (all reasonable possibilities), I load a large image in from the disk and scale it down as needed; the images are designed to scale well and later I can make multiple source images if that is desirable. But I can't figure out how to get the scaled image into GTK. This surprises me.) If there's an easy Google search, it has eluded me. -- http://mail.python.org/mailman/listinfo/python-list

As usual, posting for help after poking around for a long while guarantees you'll figure it out in the next few minutes. You need to create GDK pixbufs, which can be resized and scaled and stuff. There is definitely some room for confusion here with GTK Images, GDK Images, GTK pixbufs, and GDK pixbufs -- http://mail.python.org/mailman/listinfo/python-list

I can ship over monochrome bitmaps via XBM, but I'd rather be able to ship over full color. the first two google hits for PyGTK PIL are http://www.daa.com.au/pipermail/pygtk/2005-April/009988.html which provides a StringIO-based solution, and http://www.daa.com.au/pipermail/pygtk/2003-February/004393.html which discusses draw_rgb_image and friends, and says that if you can convert your PIL image to a pixel data string or buffer object, you could use them to display the image. here's some code that seems to do exactly that: http://www.mail-archive.com/pygtk@daa.com.au/msg07167.html (but maybe this is some kind of stupid a bitmap isn't a pixmap isn't an image thing? if so, I suggest getting a modern windowing system ;-) /F -- http://mail.python.org/mailman/listinfo/python-list

Were that the only pixbuf, that would be an atrocity. (Particularly odd for GTK, the *Gimp* windowing toolkit.) (It of course figures that was the google search; I think I tried everything but that; python imaging library pygtk isn't anywhere near as helpful, for instance.) -- http://mail.python.org/mailman/listinfo/python-list
