I'm requesting a QuickLook preview for an OmniGraffle file. The size I'm asking for is 500x300. The image I get back is much smaller, at 122x77, which looks terrible when I display it in my application. When I use QuickLook to preview the same file in the Finder, it looks great.
Why would I get such a small image back? Here's the code I'm using (courtesy of Matt Gemmell's handy extension on NSImage): NSDictionary *dict = [NSDictionary dictionaryWithObject:[NSNumbernumberWithBool:icon] forKey:(NSString*)kQLThumbnailOptionIconModeKey]; CGImageRef ref = QLThumbnailImageCreate(kCFAllocatorDefault, (CFURLRef)fileURL, CGSizeMake(size.width, size.height), (CFDictionaryRef)dict); NSLog(@"ref [%d, %d]", CGImageGetWidth(ref), CGImageGetHeight(ref)); The size passed to QLThumbnailImageCreate is documented as an upper bound. I assume that means there's no promise the returned image will actually be that size. But again, the Finder is able to get previews at any size I want. --Andy _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
