mode
Flags which control the behavior of the command.
bitsPerPixel
The number of bits per pixel to for the conversion. Valid values are 1, 2, 3, 4, 5, 6, 7, 8, 12, 16, 24, 32, 48 and 64.
order
The desired color order for the conversion.
ditheringMethod
Dithering options, useful only when the resulting image requires a palette (when it is 8 bits per pixel or less).
paletteFlags
Palette options, useful only when the resulting image requires a palette (when it is 8 bits per pixel or less).
palette
The palette used when converting the image if paletteFlags includes the ColorResolutionCommandPaletteFlags.UsePalette flag.
