Command Extract Component applied with default options.


This command allows you to extract one specific color component from the current layer. This will be represented as a grayscale layer. It is similar to Decompose, except that it extracts only one component and the effect is performed on the current layer instead of creating a new image.

Presets

Presets are a common feature for several Colors commands. You can find its description in Kohta 8.1.1, ”Colors Common Features”.

Component

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 component

Invert all pixel values of the extracted component.

Linear output

Use linear output instead of gamma corrected.

Blending Options, Preview, Merge filter, Split view
