Declaration Syntax

Visual Basic

Visual C++

public virtual IntPtr CGImageForProposedRectContextHints(
	ref NSRect proposedDestRect,
	NSGraphicsContext referenceContext,
	NSDictionary hints
)

Public Overridable Function CGImageForProposedRectContextHints ( _
	ByRef proposedDestRect As NSRect, _
	referenceContext As NSGraphicsContext, _
	hints As NSDictionary _
) As IntPtr

public:
virtual IntPtr CGImageForProposedRectContextHints(
	NSRect% proposedDestRect, 
	NSGraphicsContext^ referenceContext, 
	NSDictionary^ hints
)

Parameters

proposedDestRect (NSRect%): On input, the proposed destination rectangle for drawing the image. If NULL, it defaults to the smallest pixel-integral rectangle containing {{0,0}, [self size]}. The proposedDestRect is in user space in the reference context.

referenceContext (NSGraphicsContext): A graphics context.

hints (NSDictionary): A dictionary of hints that provide more context for selecting or generating a CGImage, and may override properties of the referenceContext.

Return Value

A CGImageRef. This may be an existing CGImage if one is available. If not, a new CGImage is created.
