CompositeToPointFromRectOperationFraction Method (aPoint, srcRect, op, delta)

Composites a portion of the image at the specified opacity to the current coordinate system. (Deprecated in Mac OS X v10.6.)

Original signature is '- (void)compositeToPoint:(NSPoint)aPoint fromRect:(NSRect)srcRect operation:(NSCompositingOperation)op fraction:(CGFloat)delta'

Available in Mac OS X v10.0 and later.

Parameters

aPoint (NSPoint): The point at which to draw the image, specified in the current coordinate system.

srcRect (NSRect): The portion of the image you want to draw, specified in the image's coordinate system.

op (NSCompositingOperation): The compositing operation to use when drawing the image to the screen. The supported compositing operations are described in “Constants.”

delta (CGFloat): The desired opacity of the image, specified as a value between 0.0 and 1.0, with 1.0 representing total opacity. Values larger than 1.0 are interpreted as 1.0. This method always expects to render something, so for values that are equal to or less than 0, this method renders at full opacity.
