With last discover of a little jung black hole by NASA, I have found this project on the Chandra X-ray observatory site:

http://chandra.harvard.edu/photo/openFITS/

IMHO it can be very effective to spread the use of GIMP having a page dedicated to the interesting / useful real case of GIMP use.

Forgive my bad english...

Thank you for a very interesting reference, I have posted it to the

Maybe it's worth taking a look at point 6 a. on http://chandra.harvard.edu/photo/openFITS/casa.html:

Another limitation of using GIMP for a 3 color image is that GIMP does not

use what are known in Photoshop as "Adjustment Layers". Adjustment Layers allow you to make changes to your layers in a non-destructive way. That is to say that you do not actually change the layer itself, you apply an additional layer to the original layer to make changes. This preserves the original layer so you can always go back to its original state at any time. The changes we'll make here have to be applied to the original layer, and once the file has been saved and closed, you cannot back out of those changes. One workaround to this is to duplicate your original layers and do all of your work on the duplicates so that you can always go back to the original if need be.

How about adding this missing feature to GIMP?

Best wishes, Łukasz Czerwiński

You know how to submit patches, don't you? :)

That's not a very useful reply. Adjustment layers have been discussed

extensively
in the past, and they are not something that a new user could simply code up and send
in a patch for. Even PhotoShop only allows adjustment layers for a specific set of
adjustment types, because it's essential that adjustments can be calculated very rapidly.
Anyway, one of the advantages of GEGL is that it may make this sort of thing easier
to implement.

I am under the impression that the functionality of adjustment layers are a very tiny subset of the capabilities that GIMP will have if GEGL is ever integrated.

Well, my point is that adjustment layers have been discussed to death already (sorry, Alexia :)) So there is not much point saing "How about implementing them" once again. At some point someone should JFDI.
