I have an NSImage which I generate by specifically creating a NSPDFImageRep and adding that to an empty image. Later this same image rep is used to write the image as a PDF file to disk.
An interface displays these images, either loaded from disk or made on the fly as above. The image's native size is quite small and they are often scaled up when drawn, but since they're PDFs that should work OK. On 10.6, these render really nicely and I always get crisp drawing. On 10.5 however, they render quite fuzzily, which I'd prefer they didn't. Obviously the problem is the bitmap caching that NSImage does, and which must have changed for PDF images in 10.6. I set the caching of the image to NSImageCacheBySize, which gives me a useful drawing speed-up compared with NSImageCacheNever, but the cached bitmaps are fuzzy on 10.5, presumably because they're being scaled up and the bitmaps cached the original size, not the drawn size. Is there anything I can do about this? I set the context's image interpolation quality to high when these are drawn. --Graham _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
