Hi Hamish,
Am I reading correctly that you have two IKImageViews stacked on top
on one another?
Is there a reason that you aren't using Core Image and using one of
the compositing filters to produce a difference that you can then
display?

Hi Gordon,
I'm not sure what you really want to do is -removeAllAnimations. I
suspect that you probably want to temporarily disable animation within
the scope of a CATransaction. Take a look at the code found here:
Depending on what you are going to do with the sub-images once you
create them, you might want to consider using a CIImage with the
CICrop core image filter.

I would suggest that you take a look at the sample code for

I don't think you missed anything. I do believe that documentation is
somewhat misleading for this class.

My quick check didn't find it there, so it may be history.

Ben,
one more suggestion - subclass the QTCaptureView and add a CALayer.
Then, do your drawing on the CALayer, as opposed to the the
QTCaptureView's Layer.
I haven't tried this myself, so it may not work... but if it does, it
provides a way for you to do your drawing without having to

QTMovieView has a delegate method
- (CIImage*) view: (QTMovieView *)Target_View willDisplayImage:
(CIImage *)New_Image
This method gives you a CIImage to play with before it is displayed in
the Target_View. Check the header file for QTMovieView.h (near the
bottom). I think

Jacob,
You may want to look at applying one or more of the numerous filters
available to you when you make your controls layer backed. I did this
with most of the controls in my HUD for an image editing application

Hi All,
Would someone provide me a pointer for how to get the mouse location
in the coordinate system of a transformed layer that is underneath the
mouse. I thought I could do something like this:
Mouse_Location = [Target_Layer convertPoint:
NSPointToCGPoint( [NSEvent mouseLocation] )
sure you switch needsDisplayOnBoundsChange to YES and then put
some drawing code into
- (void) drawInContext:(CGContextRef)ctx
I'd be keen on knowing how you get on with this - ping me back if it
works :-)
