13 Converts input strings with exactly 256 half-comma separated integer values in
14 range 0 - 255 to look-up tables that then used to modify R, G, B values.
16 This creates a generic string interface for color correction.
20 title: Red channel look-up table
24 Value is tokenised using half-comma separator into exactly 256 integer
25 values in range 0 - 255 and a loop-up table for red channel values is
26 created and applied to image. If tokenising of value fails a linear table
27 that returns input values unchanged is used instead.
30 title: Green channel look-up table
34 Value is tokenised using half-comma separator into exactly 256 integer
35 values in range 0 - 255 and a loop-up table for green channel values is
36 created and applied to image. If tokenising of value fails a linear table
37 that returns input values unchanged is used instead.
40 title: Blue channel look-up table
44 Value is tokenised using half-comma separator into exactly 256 integer
45 values in range 0 - 255 and a loop-up table for green channel values is
46 created and applied to image. If tokenising of value fails a linear table
47 that returns input values unchanged is used instead.
