Hi all,
I'm trying to capture a view and its contents as an NSImage which I
can subsequently draw in the view. The idea is that I'm trying to
'freeze' the view's content (custom sliders, buttons, menus etc) and
present this image in the view.
I'm getting mixed results when attempting to render to a CFLayerRef
e.g.:
NSRect viewRect = [self bounds];
[self lockFocus];
NSBitmapImageRep* rep = [[NSBitmapImageRep alloc]
initWithFocusedViewRect:viewRect];
[self unlockFocus];
NSImage* image = [[NSImage alloc] initWithSize:viewRect.size];
[image addRepresentation:rep];
[image drawAtPoint:NSZeroPoint fromRect:viewRect
operation:NSCompositeSourceOver fraction:1.0];
[image release];
[rep release];
Nothing appears to be drawn in the layer. Is there a better approach
that I'm missing?
Thanks,
Stephen
