Overview

iccApplyToLink is a versatile command-line tool that builds either an ICC DeviceLink profile or a .cube LUT file by applying a sequence of ICC profiles. It supports fine-grained control over rendering intents, LUT size, interpolation, and Profile Connection Conditions (PCC).

This tool is especially useful for creating link profiles for production workflows or transforming color spaces for VFX, printing, or display calibration.

Features

Supports output as ICC v4/v5 DeviceLink or .cube 3D LUT format
Accepts a sequence of profiles and rendering intents
Handles Profile Connection Conditions (-PCC)
Applies CMM Environment variables (-ENV:sig value)
Supports LUT precision and custom input ranges
Choice of interpolation methods (linear/tetrahedral)

Usage

iccApplyToLink output_file link_type lut_size option title min_input max_input use_src_xform interp profile_seq...

Example

iccApplyToLink myLink.icc 0 33 1 "My DisplayLink" 0.0 1.0 1 1 sRGB.icc 1 printer.icc 1

Parameters

output_file: Path to save the ICC or .cube output
link_type:
- 0 = ICC DeviceLink
- 1 = .cube LUT
lut_size: Grid size per dimension (e.g., 33)
option:
- For ICC: 0 = v4, 1 = v5
- For cube: precision (e.g., 4)
title: Title embedded in output
min_input / max_input: Input value range, e.g., 0.0 to 1.0
use_src_xform: 1 = use source xform from first profile, else destination
interp: 0 = linear, 1 = tetrahedral
profile_seq: Sequence of profile files and intents, optionally with:
- -ENV:TAG value to set environment sigs
- -PCC path.icc to provide connection conditions

Rendering Intents

Supports all ICC intents plus combinations:

Code	Intent
0�3	Perceptual / Relative / Saturation / Absolute
10+	Skip D2Bx/B2Dx
20+	Preview Intents
40+	BPC-enabled
50+	BDRF variations
100+	Luminance adjusted
1000+	V5 sub-profile override
