Remarks
(Raster Pro and above only) Averages a bitmap with its shifted copies.
This method creates four copies of an image. Each copy is shifted by the offset amount into one of the four directions: top, left, bottom and right. Then the bitmap is averaged with its shifted copies.
Use the DisplaceMap method to displace a bitmap's pixels horizontally and vertically according to the values of the displacement map image.
Use the Offset method to shift a bitmap's pixels horizontally and vertically.
Use the OffsetRgn method to move a bitmap region by the specified number of rows and columns.
This method can process the whole image or a region of the image. If a bitmap has a region, the effect is applied only to the region.
Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.
This method does not support signed data images. It returns the error code ERROR_SIGNED_DATA_NOT_SUPPORTED if a signed data image is passed to this method.
