Creates an indexed color space based on the specified colorspace.
public static CoreGraphics.CGColorSpace CreateIndexed (CoreGraphics.CGColorSpace baseSpace, int lastIndex, byte[] colorTable);static member CreateIndexed : CoreGraphics.CGColorSpace * int * byte[] -> CoreGraphics.CGColorSpaceParameters
- baseSpace
- CGColorSpace
The colorspace upon which the indexed color space is based
- lastIndex
- Int32
The maximum number of elements in the indexed colorspace (up to 255)
- colorTable
- Byte[]
The color table, one byte is allocated for each color component.
Returns
An indexed color space.
Remarks
An indexed color space allows developers to reprensent colors with a byte value, the actual color rendered is computed by looking up the value in the colortable array.
For example, in an 24-bit RGB colorspace, the color index 2 would be looked up as 3-byte values at index 6, 7 and 8 in the colorTable byte array.
The number of elements in this array is the value of lastIndex multiplied by the number of components in the baseSpace.
