usage: transicc [flags] [CGATS input] [CGATS output]
flags:
-v<0..3> - Verbosity level
-e[op] - Encoded representation of numbers
-w - use 16 bits
-x - Hexadecimal
-s - bounded mode (clip negatives and highlights)
-q - Quantize (round decimals)
-i<profile> - Input profile (defaults to sRGB)
-o<profile> - Output profile (defaults to sRGB)
-l<profile> - Transform by device-link profile
Built-in profiles:
*Lab2 -- D50-based v2 CIEL*a*b
*Lab4 -- D50-based v4 CIEL*a*b
*Lab -- D50-based v4 CIEL*a*b
*XYZ -- CIE XYZ (PCS)
*sRGB -- sRGB color space
*Gray22 - Monochrome of Gamma 2.2
*Gray30 - Monochrome of Gamma 3.0
*null - Monochrome black for all input
*Lin2222- CMYK linearization of gamma 2.2 on each channel
-t<n> rendering intent:
0 - Perceptual
1 - Relative colorimetric
2 - Saturation
3 - Absolute colorimetric
10 - Perceptual preserving black ink
11 - Relative colorimetric preserving black ink
12 - Saturation preserving black ink
13 - Perceptual preserving black plane
14 - Relative colorimetric preserving black plane
15 - Saturation preserving black plane
-d<0..1> - Observer adaptation state (abs.col. only)
-b - Black point compensation
-c<0,1,2,3> Precalculates transform (0=Off, 1=Normal, 2=Hi-res, 3=LoRes)
-n - Terse output, intended for pipe usage
-p<profile> - Soft proof profile
-m<0,1,2,3> - Soft proof intent
-g - Marks out-of-gamut colors on softproof
