Hi Graham,
I tried what you have suggested still only images are shown with
titles.
I'm not clear what the problem is - what did you expect to see?
- (NSString*) imageSubtitle
{
NSDictionary* attribs = [image imageAttributes];
int w, h;
w = [[attribs objectForKey:@"PixelWidth"] intValue];
h = [[attribs objectForKey:@"PixelHeight"] intValue];
return [NSString stringWithFormat:@"%d x %d", w, h];
}
This won't work - NSImage doesn't have a method called -
imageAttributes. In my code the attributes are retrieved using [self
imageAttributes], and that method looks like this:
- (NSDictionary*) imageAttributes
{
// returns the image's attributes dictionary using CGImageSource to
read the file's header. This is fast as the image
// itself isn't loaded.
NSURL* url = [NSURL fileURLWithPath:mPath];
CGImageSourceRef srcRef = CGImageSourceCreateWithURL((CFURLRef) url,
NULL );
NSDictionary* imgProps = (NSDictionary*)
CGImageSourceCopyPropertiesAtIndex( srcRef, 0, NULL);
CFRelease(srcRef);
//NSLog(@"attributes for '%@': %@", mPath, imgProps );
return [imgProps autorelease];
}
I suspect your method is asserting when it's called due to the
unimplemented method and that is stopping the browser view working
properly. Check your console output.
