Parameters

buffer

The input buffer.

bufferOffset

The zero-based offset into the buffer where conversion should start.

width

Width in pixels of the input image data.

inBitsPerPixel

BitsPerPixel of the input image data.

outBitsPerPixel

BitsPerPixel of the desired output image data.

inOrder

The input color order.

outOrder

The output color order.

inPalette

The palette or 8-bit LUT for the existing data, before conversion. If the input data is not palettized and not grayscale, use NULL.

outPalette

The palette for the converted data. If the data is converted to 16 or 24 bits per pixel color, use NULL for no palette.

alpha

The alpha value if the destination bits per pixel contains an alpha component

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.
