ImageData

ImageData[data, opts] is the default ImageProcessing data structure for monochrome and color images.

ImageData is a new Mathematica object that facilitates the easy manipulation and handling of single-channel and multichannel images.

ImageData is the default return value of the ImageRead function.

ImageData has two options that define the pixel-interleaving method and the color function, respectively. The permitted values follow.

Option	Option
PixelInterleave	None	single-channel format
	True	meshed multichannel format
	False	planar multichannel format
ColorFunction	GrayLevel	grayscale color space
	RGBColor	RGB color space
	Hue	HSV color space
	CMYKColor	CMYK color space
	CIELABColor	CIE L^a^b^* color space
	CIELUVColor	CIE L^u^v^* color space
	CIEXYZColor	CIE XYZ color space
	None	generic color space

Raw pixel data may be converted to an ImageData expression with functions: ToGrayLevel, ToRGBColor, ToCMYKColor, ToHSVColor, ToCIEXYZColor, ToCIELUVColor, ToCIELABColor, and ToGenericColor.
