IndexedColorSpace Class Documentation

class IndexedColorSpace : ColorSpace

Namespace:Datalogics::PDFL

Inherits from:
ColorSpace

Detailed Description

Indexed color spaces are used to reduce the amount of memory used for processing images.

Indexed color spaces are used when a limited number of colors are needed.

Commonly, an image with an indexed color space can be one third the size of the same image with a standard color space, because the indexed image uses a smaller palette of colors.

Constructor & Destructor Documentation

IndexedColorSpace

IndexedColorSpace(ColorSpace base_, int hival, System.Collections.Generic.IList< System.Int32 > lookup)

Parameters

base_: ColorSpace
hival: int

an integer that specifies the maximum valid index value. In other words, the color table is to be indexed by integers in the range 0 to hival. hival can be no greater than 255.

lookup: System.Collections.Generic.IList< System.Int32 >

a list of integers in the range 0..255. There must be m * (hival + 1) values, where m is the number of components of the base color space.

Create a Indexed color space.
