Why not check out the GIMP registry for more scripts? The registry can be found here. Make sure you get a script compatible with your version of the GIMP.
Tools
If you've got GIMP version 2.3.5 and you find a script you think might be really cool but it's for a previous version, try the script update tool in our tools section.
The Goal
gm-channel-extract is a Gimp channel ops script. Also known as the 18 scholars, it allows you to extract any combination of the 17 greyscale channels from the color components of the image. These greyscale images will be added as layers to the original image. These greyscale layers can be used for many purposes, including black and white conversion, photo retouching, creating masks and many other uses. The script registers itself in:
- script-fu/lasm's FX effects/Utils/Channel Extract
This sample shows the Black channel from the CMYK color component of the original. Hover your mouse over the image below to see the result of CMYK-Black channel extract.
This is the result of extracting the Value of the Hue-Saturation-Value color component of the original image. Hover your mouse over the image below to see the result of Value channel extract.
The next example shows the greyscale channel extracted from the yellow component of the CMY (Cyan Magenta Yellow) color composition. Hover your mouse over the image below to see the result of Yellow channel extract.
