[Gimp-user] FW: Question on copy from selection

[hcabral at excite.com]

Hi there,

I would like to thank saulgoode at flashingtwelve.brickfilms.com for his very thorough reply to my question on the contents of the RGB channels of a layer created from a selection.  He managed at once to make my question more understandable, give an explanation on gimp's behavior in this case, and provide solutions to the problem.

For what I needed (run a plug-in that would use the layer created from the selection to perform some operations on the original layer), due to an error in the plug-in I really needed the RGB channels to have information only in the areas selected, and after much tweaking (I'm not exactly a Gimp expert) I found out about the decompose function (image -> mode -> decompose), operated on the individual layers, and then applied compose to put them together in a single layer.  Maybe not the simplest way but it worked (I actually ended up doing a workaround that doesn't use selection to create the layer but that's another story).

Thanks again.  Regards,

Hermano Cabral

PS: Thanks also for the tip with the script.  I think that it is going to be useful in many other situations, too.
