public class CalRGB
extends PColorSpace

A CalRGB colour space is a CIE-based ABC colour space with only one transformation stage instead of two. In this type of space, A, B, and C represent calibrated red, green, and blue colour values. These three colour components shall be in the range 0.0 to 1.0; component values falling outside that range shall be adjusted to the nearest valid value without error indication. The decoding functions (denoted by “Decode ABC� in Figure 22) are gamma functions whose coefficients shall be specified by the Gamma entry in the colour space dictionary (see Table 64). The transformation matrix denoted by “Matrix ABC� in Figure 22 shall be defined by the dictionary’s Matrix entry. Since there is no second transformation stage, “Decode LMN� and “Matrix LMN� shall be implicitly taken to be identity transformations.

Since:

1.0
