Thanks for the response. If I were a debian user, perhaps I would have... I actually did see a reference tiffcp in my Googlings, but it didn't seem to directly address the issue of writing a QImage (memory) to a G4-compressed TIFF file. I'm hoping for a cross-platform solution, across Mac, Linux, and Windows. I'd also rather compress the file before writing it out to disk, and then making a compressed copy after writing it... saves wear and tear on the disk. The closest that I've found so far is http://artis.imag.fr/Software/TiffIO/#DWN but it looks rather frightening to attempt to build and install on three different platforms, for a novice Python, novice Qt user. It is also a couple years old, mentioning Qt 4.0.1 rather than current releases. Of course, a pure Python solution is likely to be slow in CPU performance... so maybe I should gain 6 months experience and then look at this again. _______________________________________________ PyQt mailing list [email protected] http://www.riverbankcomputing.com/mailman/listinfo/pyqt
