Gamut Mask Tools

Purpose

Generating gamutmask images from existing image files like this (width/height=250, paddingX/paddingY=2)

Van Gogh Starry Night

Gamutmask tool once executed generates gamutmask images for every image found in the input folder. By default it runs until stopped thus monitoring for updated or added files.

To run only once:

$ gamutmask -once

To run recursively:

$ gamutmask -recursive

To modify output folder by passing -output parameter:

$ gamutmask -output ./output

The tool monitors the ./_input folder for images unless requested to do it once. The folder can also be changed by passing a value for -intput parameter:

$ gamutmask -input ./input

For help issue

$ gamutmask help

Command line also supports the following parameters:

• width
• height
• paddingX
• paddingY
