Class SrgbConverter
- ColorSpaceConverter
Note the matrix numbers used here are NOT identical to those in the
w3 spec, as those numbers are CIE XYZ relative a D65 white point.
The CIE XYZ we use is relative a D50 white point, so therefore a
linear Bradford transform matrix for D65->D50 mapping has been applied.
(The ICC documents describe this transform)
Linearized Bradford transform:
0.8951 0.2664 -0.1614
-0.7502 1.7135 0.0367
0.0389 -0.0685 1.0296
Inverse:
0.9870 -0.1471 0.1600
0.4323 0.5184 0.0493
-0.00853 0.0400 0.9685
