RenderToBufferWithBytesPerRowPixelFormatForBounds Method (baseAddress, rowBytes, format, bounds)

Renders a subregion of the image into the supplied memory buffer using the specified pixel format. (required)

Original signature is '- (BOOL) renderToBuffer:(void*)baseAddress withBytesPerRow:(NSUInteger)rowBytes pixelFormat:(NSString*)format forBounds:(NSRect)bounds'

Available in Mac OS X v10.5 and later.

Declaration Syntax

Visual Basic

Visual C++

bool RenderToBufferWithBytesPerRowPixelFormatForBounds(
	IntPtr baseAddress,
	NSUInteger rowBytes,
	NSString format,
	NSRect bounds
)

Function RenderToBufferWithBytesPerRowPixelFormatForBounds ( _
	baseAddress As IntPtr, _
	rowBytes As NSUInteger, _
	format As NSString, _
	bounds As NSRect _
) As Boolean

bool RenderToBufferWithBytesPerRowPixelFormatForBounds(
	IntPtr baseAddress, 
	NSUInteger rowBytes, 
	NSString^ format, 
	NSRect bounds
)

Parameters

baseAddress (IntPtr): The base address of the memory buffer. The Quartz Composer engine passes you an address that is aligned on a 16-byte boundary.

rowBytes (NSUInteger): The number of bytes per row of the image data. The Quartz Composer engine guarantees this value is a multiple of 16.

format (NSString): The pixel format of the image data.

bounds (NSRect): The bounds of the subregion.

Return Value

YES if the image is rendered successfully into the buffer; NO on failure or if the image provider doesn’t support CPU rendering.
