All of a sudden after many years of printing with QTR(Gui), I'm getting the same message. The odd thing is that it's not with all TIFF files. It's not dependent on the file size in Mb, as some 400Mb files are ok but 100Mb files are not. I can't see any difference in the structure of those files that generate the error and those that don't - no channels or paths in the TIFF, and some files with layers are ok, whereas even if I flatten the problem files they still generate the error message. Pixel Order is interleaved, byte order is IBM PC, no compression or image pyramid. A fresh install of QTR didn't help, unlike docsocks41, nor a reboot.
What I did discover via trial and error is if sample down to reduce the pixels, the problem eventually goes away. The image is to be printed on a 13"x19" page with a 1" margin at 720ppi, and that's about 84,000,000 pixels. If I sample down to 640ppi it's ok but not at 650. Is there a pixel limit in QTRGui? It doesn't seem to matter whether they're 8 or 16 bit pixels.
What is worrying is that one file that I'm certain printed alright this evening now generates the error. This makes me worry that it's a growing limitation of my system, rather than QTRGui.
Any insights?
