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.
