Description forthcoming.

compositeToPoint: fromRect: operation: 

- (void) compositeToPoint: (NSPoint)aPoint fromRect: (NSRect)aRect operation: (NSCompositingOperation)op;

Description forthcoming.

compositeToPoint: fromRect: operation: fraction: 

- (void) compositeToPoint: (NSPoint)aPoint fromRect: (NSRect)srcRect operation: (NSCompositingOperation)op fraction: (float)delta;

Description forthcoming.

compositeToPoint: operation: 

- (void) compositeToPoint: (NSPoint)aPoint operation: (NSCompositingOperation)op;

Description forthcoming.

compositeToPoint: operation: fraction: 

- (void) compositeToPoint: (NSPoint)aPoint operation: (NSCompositingOperation)op fraction: (float)delta;

Description forthcoming.

delegate 

- (id) delegate;

Description forthcoming.

dissolveToPoint: fraction: 

- (void) dissolveToPoint: (NSPoint)aPoint fraction: (float)aFloat;

Description forthcoming.

dissolveToPoint: fromRect: fraction: 

- (void) dissolveToPoint: (NSPoint)aPoint fromRect: (NSRect)aRect fraction: (float)aFloat;

Description forthcoming.

drawAtPoint: fromRect: operation: fraction: 

- (void) drawAtPoint: (NSPoint)point fromRect: (NSRect)srcRect operation: (NSCompositingOperation)op fraction: (float)delta;

Calls -drawAtPoint:fromRect:operation:fraction: with dstRect given by point and the size of srcRect.

drawInRect: fromRect: operation: fraction: 

- (void) drawInRect: (NSRect)dstRect fromRect: (NSRect)srcRect operation: (NSCompositingOperation)op fraction: (float)fraction;

Takes the part of the receiver given by srcRect and draws it in dstRect in the current coordinate system, transforming the image as necessary.

The image is drawn as if it was drawn to a cleared window, then dissolved using the fraction delta to another cleared window, and finally composited using op to the destination.

Note that compositing and dissolving doesn't work on all devices (printers, in particular).
