I'd say that letting the view do the scaling is definitely the easiest way to

Vincent,
Have you checked the values of dx and dy in the debugger? Shouldn't those
variables be declared as CGFloats as opposed to int?
In regards to resizing the layer when the enclosing view resizes, what values
have you set for the layer's autorezingMask property?

You should perform whatever blending you need to do on the image itself to
create a new image which you can then just put into a UIImageView like you

Create a context with UIGraphicsBeginImageContext, apply your blend, and get

and don't forget to end your context.

An image doesn't carry a blend mode, merely the image data. You *draw* the

Yes it is. The contents property is generally used to represent bitmapped
content of a layer, which in the case of a plain CALayer means that anything
drawn via -drawInContext: or -drawLayer:inContext: will be accessible via the
contents property.
