| - | Xcalib is simple and effective colour management software. It does one thing: adjust the colour profile of your display. | ||

| - | <WRAP indent> | ||
| - | Xcalib is a simple command. It adjusts the colour profile of your display, and that's all. If you are looking for a graphical control panel that claims to assist you to find the best gamma level based on your own perception, this is probably not the tool for you. | ||

| - | =====Install===== | ||
| - | |||
| - | Install ''xcalib'' from [[http://slackbuilds.org]]. | ||
| - | |||
| - | =====Usage===== | ||
| - | |||
| - | Xcalib has two use-cases: | ||
| - | |||
| - | * Load a pre-defined colour profile into your display. | ||
| - | * Adjust the current colour profile of your display. | ||
| - | |||
| - | **Load a Colour Profile** | ||
| - | |||
| - | <WRAP indent> | ||
| - | To load a colour profile, just invoke xcalib along with the path to your colour profile: | ||
| - | |||
| - | <code> | ||
| - | $ xcalib /usr/share/color/icc/eciRGB_v2_profile-2011/eciRGB_v2_ICCv4.icc | ||
| - | </code> | ||
| - | |||
| - | Ideally, you will have created a colour profile for your monitor with a colour calibrator like [[http://www.hughski.com/|Color Hug]], or else managing colour profiles of your screen is probably not doing much good. | ||
| - | |||
| - | To have this happen automatically upon boot, add that command to your ''~/.bash_profile'' file. | ||
| - | </WRAP> | ||
| - | |||
| - | **Alter a Colour Profile** | ||
| - | |||
| - | <WRAP indent> | ||
| - | Make fine adjustments to the current colour profile of your display with a trailing ''-a'' or ''-alter'' flag. For instance, to boost the blue levels of your current profile: | ||
| - | |||
| - | <code> | ||
| - | $ xcalib -blue 1.0 10.0 100.0 -a | ||
| - | </WRAP> | ||
| - | |||
| - | Which takes the blue at gamma level 1.0 (1 through 5 are valid), and sets its brightness to 10% and its contrast to 100%. | ||
| - | |||
| - | To lower the blue in the current profile: | ||
| - | |||
| - | <code> | ||
| - | $ xcalib -blue 1.0 10.0 60.0 -a | ||
| - | </code> | ||
| - | |||
| - | Which takes the blue levels at 1.0 gamme and sets its brightness to 10% but its contrast to 60%. | ||
| - | |||
| - | These settings can be done to ''-red'', ''-green'', or ''-blue''. | ||
| - | |||
| - | Calibration alterations can be re-set with ''-c'' or ''-clear'': | ||
| - | |||
| - | <code> | ||
| - | $ xcalib -c | ||
| - | </code> | ||
| - | |||
| - | To automate xcalib, add an xcalib command to your ''~/.bash_profile'' file. | ||
