Hi Larry! Thanks for the quick reply! > Are you going through the images sequentially? Does your app have any > knowledge about when it will not need a file for a while? Or is it truly > unpredictable random access? In the test, I'm currently going through 2500 files in a single directory sequentially. In the app, I'll be trawling a complex directory structure, so its more than liking going to be unpredictable

Since in Python, we'll be doing this by isolating the alpha, getting the pixels, and pushing the resultant array into numpy. When implementing just the first part (checking some attributes), we noticed the slowdowns when reading the files. I don't *THINK* its related to reading DDS files, so testing another format at the moment (tga). > Also, which platform? Windows Thanks! -J _______________________________________________ Oiio-dev mailing list [email protected] http://lists.openimageio.org/listinfo.cgi/oiio-dev-openimageio.org
