Assemble RGB image from 3 grayscale images

Hi,

i'm trying to assemble 3 grayscale images (each of them representing a single R, G, B channel of the same picture) into a single colour image. I haven't found a way to copy the grayscale data just into a single channel - it always goes to all three channels.

Do i need to write a plugin to achieve this, or is there an out-of-the-box method to do this?

any help appreciated.

Assemble RGB image from 3 grayscale images

Put the channels into three layers of an image and use Plugins->Colours->Compose-> RGB

No need of the first step, just use the plugin on one of them and select the other images there.
