Draws all or part of the image in the specified rectangle in the current coordinate system.

Original signature is '- (BOOL)drawInRect:(NSRect)dstSpacePortionRect fromRect:(NSRect)srcSpacePortionRect operation:(NSCompositingOperation)op fraction:(CGFloat)requestedAlpha respectFlipped:(BOOL)respectContextIsFlipped hints:(NSDictionary *)hints'

virtual bool DrawInRectFromRectOperationFractionRespectFlippedHints(
	NSRect dstSpacePortionRect, 
	NSRect srcSpacePortionRect, 
	NSCompositingOperation op, 
	CGFloat requestedAlpha,

Parameters

dstSpacePortionRect (NSRect): The rectangle in which to draw the image, specified in the current coordinate system.

srcSpacePortionRect (NSRect): The source rectangle specifying the portion of the image you want to draw. The coordinates of this rectangle must be specified using the image's own coordinate system. If you pass in NSZeroRect, the entire image is drawn.

op (NSCompositingOperation): The compositing operation to use when drawing the image. See the NSCompositingOperation constants.

requestedAlpha (CGFloat): The opacity of the image, specified as a value from 0.0 to 1.0. Specifying a value of 0.0 draws the image as fully transparent while a value of 1.0 draws the image as fully opaque. Values greater than 1.0 are interpreted as 1.0.

respectContextIsFlipped (Boolean): YES if the flipped context of the receiver should be respected, otherwise NO.

hints (NSDictionary): An optional dictionary of hints that provide more context for selecting or generating the image. See Image_Hint_Dictionary_Keys for a summary of the possible key-value pairs.

Return Value

YES if the image was successfully drawn; otherwise, NO.
