Parameters

page

Image to reduce bit depth.

colorSpace

Color space to reduce image to.

channelDepths

Channel depths to reduce image to.

reductionMethod

Method to use for reducing bit depth.

options

Options to use for reduction, or set to null to use defaults.

All methods except for ImGearReductionMethods.SCALE change the color space of the image to Indexed. ImGearReductionMethods.SCALE does not change the image's color space, but only scales the channel depths. Different reduction methods have their own options, which can be set using the options parameter.

For more information about a particular method, see its options. The following reduction methods are available in ImGearReductionMethods:

Method	Input color spaces and bit depths	Output color spaces and bit depths	Options
BAYER	RGB (24)Grayscale (8)Indexed (>1)	Indexed (1 or 4)	ImGearBayerReductionOptions
