as all the nice system services that were CGWindowListCreateImage, lockFocus are now deprecated, and drastic restictions are imposed to CALayer/renderInContext:, i just cant figure out how to design a single generic obj C method to capture the content of an NSView , whatever this view is ( subclassed or not, layer backed of not ). As simple as that. this was the method, which now no longer works : //============================================================================= +(NSImage*) viewImageShot:(NSView*)view :(BOOL)bFlip //============================================================================= // capture an NSImage of the given view content // pass window.contentView to capture the whole window,cropping the title bar { CGFloat wantedLayer = view.wantsLayer; BOOL wasHidden= view.hidden; view.hidden= NO; view.wantsLayer= YES; NSImage *requiredImage = [[NSImage alloc] initWithSize:view.bounds.size]; [requiredImage lockFocus]; CGContextRef context= [[NSGraphicsContext currentContext] CGContext]; if(bFlip) FlipContext(context, view.bounds.size.height); [view.layer renderInContext:context]; [requiredImage unlockFocus]; view.wantsLayer = wantedLayer; view.hidden = wasHidden; return requiredImage; } Is there here some hope to get some help or direction to acheive this goal ? thanks to those whow will answer.
