Note: This method will also work for 12 and 16-bit grayscale images, but only in the Document/Medical Imaging editions. If you attempt to use this method with a 12 or 16-bit grayscale image, but you do not have a Medical Imaging edition, it will throw an exception.
The conversion uses only one buffer, which must be large enough to hold the data before and after conversion.
Image data that is 8 bits per pixel or less must use a palette, and this method can use such data as input, output, or both. Therefore, you may need to specify the palette for the input, or for the output, or both.
If either inBitsPerPixel or outBitsPerPixel is 16, flags is used to determine whether the data should be treated as color or grayscale.
If nBitsPerPixelSrc is 12, it is assumed to be grayscale. However, the flags parameter should also reflect that it is grayscale for future compatibility. If the source is grayscale, inPalette can be set to a palette. The palette should contain N entries. If the source uses lowBit and highBit, then N equals 2 raised to the power of (highBit - lowBit + 1). Otherwise, N equals 2 raised to the power of inBitsPerPixel.
The flags parameter supersedes inOrder and outOrder. If you specify RasterByteOrder.Bgr for inOrder, but use RasterConvertBufferFlags.SourceGray in flags, it will be assumed that the source buffer contains grayscale data.
