A collection of tools for Gaffer primarily focusing on image, color, and plotting.

First, clone this repo to some location on disk, let's call it /path/to/gaffer-tools. Second, we'll need to set up a couple of environment variables so that the nodes are loaded into the node menu. I'll use Bash in this example but you can adapt it to your needs. We use the GAFFER_STARTUP_PATHS to execute loadNodes.py on startup. This script adds all .grf Gaffer Reference Files and .gfr Gaffer Script Files into the node menu, re-creating the directory structure of the folders on disk in the node menu.

# Add startup directory to GAFFER_STARTUP_PATHS so `loadNodes.py` is executed on startup.
export GAFFER_STARTUP_PATHS=/path/to/gaffer-tools/startup:${GAFFER_STARTUP_PATHS}

# Add GAFFER_TOOLS_ROOT so gfr and grf files under tools are auto-loaded in the node menu.
export GAFFER_TOOLS_ROOT=/path/to/gaffer-tools/tools

If environment variables are inconvenient, you can also copy the loadNodes.py file into your ~/gaffer/startup/gui folder, and hard-code the filepath in that python file by setting the GAFFER_TOOLS_ROOT variable to /path/to/gaffer-tools.

Nodes are provided as .grf Gaffer Reference files.
