Details:
i am trying to use the following category (works on Mac OS X) to capture the
contents of an NSView including subviews as an NSImage but it doesn't work as
there is an exception somewhere deep in
bitmapImageRepForCachingDisplayInRect:
@implementation NSView (NSView_Snapshot)
- (NSImage *)snapshotIncludingSubviews
{
NSBitmapImageRep *imageRep = [self
bitmapImageRepForCachingDisplayInRect:self.bounds];
NSImage *renderedImage = [[NSImage alloc] initWithSize:[imageRep size]];
[self cacheDisplayInRect:self.bounds toBitmapImageRep:imageRep];
[renderedImage addRepresentation:imageRep];
return [renderedImage autorelease];
}
@end
minimal runnable sample project to illustrate the issue attached
issue occurs in SVN trunk as of today as well as a few months ago.
