The Negative plugin provides immediate, high-contrast windows for the visually impaired by inverting the colors of individual windows, or all windows at once.
This plugin requires that you have the GL_ARB_fragment_program extension. It must be available with your graphics card, and your X Server must expose it.
Usage
Enable/Disable [Focused] Window Negative |
<Super>n |
Enable/Disable Screen Negative |
<Super>m |
Configuration
Window Matching is used to determine which windows are affected or unaffected by Negative:
Neg Windows - By default, any (ie. all) focused windows will be affected.
Exclude Windows - By default, only windows of type=Desktop are excluded from the effect.
