	IReadableBitmapData^ source, 
	Rectangle sourceRectangle, 
	KnownPixelFormat pixelFormat,

[<ExtensionAttribute>]
static member Clone : 
        source : IReadableBitmapData * 
        sourceRectangle : Rectangle * 
        pixelFormat : KnownPixelFormat * 
        ditherer : IDitherer -> IReadWriteBitmapData 

Parameters

source  IReadableBitmapData

An IReadableBitmapData instance to be cloned.

sourceRectangle  Rectangle

A Rectangle that specifies the portion of the source to be cloned.

pixelFormat  KnownPixelFormat

The desired pixel format of the result.

ditherer  IDitherer

The ditherer to be used. Might be ignored if pixelFormat represents an at least 24 bits-per-pixel size.

Return Value

Usage Note

If pixelFormat can represent a narrower set of colors, then the result will be automatically quantized to its color space. To use dithering a ditherer must be explicitly specified.

Color depth of wide-color formats (Format16bppGrayScale, Format48bppRgb, Format64bppArgb, Format64bppPArgb) can be preserved only between the same pixel formats. If pixel formats are different, then colors might be quantized to 32bpp ones during the operation.
