Figur 16.192. Extract Component applied
Original image
Command “Extract Component” applied with default options.
These options are common to GEGL-based filters. Please refer to Afsnit 2, “Fælles funktioner”.
Component to extract. Default is RGB Red: all layer pixels that have the red component in their color will be extracted to create gray pixels; gray pixel value is that of the red channel (e.g a 153;70;17 RGB pixel will give a 153;153;153 gray pixel).
Invert the extracted component.
Use linear input instead of gamma corrected.
