DrawInRectFromRectOperationFraction Method (__target, dstRect, srcRect, op, delta)

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

Original signature is '- (void)drawInRect:(NSRect)dstRect fromRect:(NSRect)srcRect operation:(NSCompositingOperation)op fraction:(CGFloat)delta'

Available in Mac OS X v10.4 and later.

Declaration Syntax

Visual Basic

Visual C++

public static void DrawInRectFromRectOperationFraction(
	this CIImage __target,
	NSRect dstRect,
	NSRect srcRect,
	NSCompositingOperation op,
	CGFloat delta
)

<ExtensionAttribute> _
Public Shared Sub DrawInRectFromRectOperationFraction ( _
	__target As CIImage, _
	dstRect As NSRect, _
	srcRect As NSRect, _
	op As NSCompositingOperation, _
	delta As CGFloat _
)

[ExtensionAttribute]
public:
static void DrawInRectFromRectOperationFraction(
	CIImage^ __target, 
	NSRect dstRect, 
	NSRect srcRect, 
	NSCompositingOperation op, 
	CGFloat delta
)

Parameters

__target (CIImage): The target instance.

dstRect (NSRect): The rectangle in which to draw the image.

srcRect (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.

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

delta (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.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type CIImage. When you use instance method syntax to call this method, omit the first parameter.
