Adding Star Mask as Layer Mask in GIMP...Help please

[StargeezerTim]

Hope this the right forum for this!

I have created a star mask in DSS and want to add it as a Layer Mask to an Image layer in GIMP.

I created a Layer Mask, then tried to copy the contents of the star mask and paste it into the layer mask, but I get another 'floating Layer'.

Has anyone done this who can direct me how to add the star mask to the layer mask, or is there another way of using it? I want to use it so I can change the colours of galaxies whilst keeping the stars as they were.

Thanks, Tim. 

p.s. Not that experienced in using layers, but happy to learn!

Thanks Steve,

Unfortunately not....   I can create a layer mask as described in the tutorial, what I want to do is use the star mask created in DSS as the layer mask, i.e copy or import the star mask into the Layer mask. I'm sure there is a simple way to do, but i am just too simple to work it out! 

Cheers, Tim.

Try Doug's tutorial on Star Masks ... PS based but the principles apply the same ...

Looks at the layers help, there is a "Channel" option, which says "With this option the layer mask is initialized with a selection mask you have created before, stored in the Channel dialog.". So if you can get your mask into a channel then maybe this will work!?

Or maybe follow this http://blog.irisquest.net/2008/02/gimp-using-imagelayer-as-layer-mask_7418.html ?
