The image memory must be locked when you use this method. Normally, you can call Access to lock the memory before starting an operation that uses this method. Then call Release when the operation is finished.
You can use the BitsPerPixel property of the image to determine the number of bytes to set the bufferCount parameter. If the image is 8-bit then each byte is an index to the palette. If the image is a 24-bit image, then each three bytes represents one pixel element. Color order is determined by the Order property of the RasterImage object. This value can be RasterByteOrder.Rgb, RasterByteOrder.Bgr, or RasterByteOrder.Romm.
RasterByteOrder.Gray is only valid for 12 and 16-bit grayscale images. Support for 12 and 16-bit grayscale images is only available in the Document/Medical Imaging editions.
