compose/decompose?

May 8, 2008 - 00:02 — poetic_cheese

Okay, so I was trying out this tutorial called '"smart" sharpening' and one of the first steps is to go to Image -> Mode -> Decompose, and then select LAB or HSV, but I don't have an 'decompose' option. I looked through the plug-ins but there's nothing about compose/decompose. I have the newest version of gimp, I think. It just says GIMP 2. But anyway, I have no idea about this kind of thing. Can anyone help? It would be much appreciated! Thank you ahead of time!

Older version

The tutorial was for an older version. Those used to be under the image menu.

im having this same

im having this same problem.

I go to where decompose but for some reason i cant select the option.

Its not in bold and i cant click on it but i can see its there.

Its the same for many other options.

Do i have to do something to the image before i can use decompose? Iv copied it but do i need to add layers or something?

Sorry for the stupid questions but im quite new at gimp

cheers

Should be in RGB image mode

To decompose a image in RGB (or Lab or CYMK) image should be in RGB mode, since you have many other menu items disabled,i bet you are in index (you opened a gif?) or in greyscale mode

To fix Image/image mode/rgb

except that decompose only need a image be opened.
