This script contains a few simple tools related to luminance.
It installs three separate scripts under Filters/Luminance. These are:
Extract - this extracts a layer's luminance to a separate layer, and leaves only the chroma information to the other layer. You can get the original layer back by merging the layers.
Remove - this removes luminance information from a layer, ie. sets the luminance to 50% on the whole layer. Basically it makes the layer into a chroma layer.
Hue/Saturation - this uses the two previous scripts internally to adjust hue or saturation of a layer while keeping the luminance intact. The standard H/S/L tool of GIMP does not preserve luminance, when you adjust hue or saturation with it.
- note that you have to rename the file to .py instead of .py.txt -

Very cool plugin dd.
Very cool plugin dd. Extremely fast too and it will be used (much faster then Luma invert 50% opacity technique that I usually use and I get the Luminance layer itself as an extra). Thanks a heap. :)
I agree
Very nice plugin dd, and thanks for sharing it. :)
Nice plugin

Thanks guys.
This is a simple script, and it has some limitations... I wrote about it in gimpchat, here -> http://www.gimpchat.com/viewtopic.php?f=9&t=2411&view=unread#p31263
I am planning on improving the script in the future.
