 Except for one thing: layers don't print out as solid.

As far as I can see the result of Apply Image is a layer.

 I'm not suggesting that this be implemented anytime soon - but it
 would be nice to have better channel mixing abilities once GIMP is
 using GEGL for composition...

Now we are getting to a point. So your post is not actually about Apply
Image, but about missing channel mixing abilities. It would help if you
could point out exactly what it is that you can't do in GIMP. Otherwise
we will never enhance the channel mixing abilities, using GEGL or not.

As far as I can see the point you are trying to make is that GIMP
doesn't allow you to use channels for layer blend operations. I've tried
to reproduce your example using channels and layers and indeed it
appears impossible. I can easily copy a spot channel to a new layer by
dragging it from the channels to the layers dialog, but the result will
be the grayscale channel. Perhaps it would help if we would change that
so it creates an RGBA layer that represents the spot channel. This layer
would be filled with the channel spot color and the grayscale mask of
the channel would be transferred to the layers' alpha channel. Does that
make any sense? Would such a change break other workflows?

I like this idea.  I would use it frequently.  In fact, I would suggest
calling it Duplicate Visible in the menu, and also adding it to the
buttons at the bottom of the layers dialog with a description of Duplicate
visible layers as single new layer on mouse-over.  As far as real estate on
the bottom of the layers dialog goes, I would eliminate the raise/lower
layer buttons  I don't ever use them since it is easier to drag the
layer itself to the new location than to select the layer with one mouse
click and then find and click on the raise/lower button.

In my opinion, a better solution to the copy visible to new layer  
functionality would be to add an option to Merge Visible Layers which  
would retain the original visible layers. This approach would seem  
more intuitive and would not entail an additional menu command. It  
would also be more flexible because the newly created layer wouldn't  
need to be the image size (the user would have available the  
expansion/clipping options of Merge Visible).

The proposed Add Border script doesn't provide the same functionality  
as the existing one (it doesn't provide the same 3-D effect) and, in  
my opinion, if considered at all, it should be as an additional  
script, not a substitute. As a minor nit, if the feathering option is  
chosen along with increasing the canvas size, the result is a border  
with semi-transparent regions (which hardly seems of any use  
whatsoever).

Personally, I don't find the proposed script worth adding to the GIMP  
base. The result it achieves can readily be accomplished with a couple  
of additional (and intuitive) steps being performed after running the  
current Add Border script. The gradient options are more flexibly  
handled manually (doing an alpha to selection or lock alpha on the  
border layer and blending) and feathering is trivially accomplished  
with a Gaussian blur.

Adding an option to the existing Add Border script which would permit  
specifying whether it is an inside border or outside seems reasonable  
and shouldn't affect too many (if any) existing scripts (none of  
GIMP's scripts seem to rely upon its present behavior).

Quoting Alchemie foto\\grafiche [EMAIL PROTECTED]:



 i know that many good scripts are not included  to preserve the Gimp  
  code essential and easy to maintain..a  excellent reason .

 But in this case the script fill a basic missed feature often   
 required by many users

 The feature in Photoshop is called apply imagine APPARENTLY in   
 gimp that may be accomplished by  3 steps (copy visible-paste -add a  
  new layer )

 APPARENTLY .. because those 3 steps will lead often to unwanted   
 results,and there is not any warning about:
  if was a selection that will get lost in the process ... then to   
 recover selection would be needed Undo..  that means  no too   
 experienced users risk to loop forever without solve

 Solution  would be use 6 steps instead then 3 (save selection to a   
 channel-select all -copy visible-paste-add new layer-reload   
 previous selection from channel) and that is very unfriendly, as is   
 unfriendly force users to deal with floating selection  for a such  
  basic and simple task

 The script solve all this with a single click

 I'm not the author of the script anyway is released under GPL and   
 i'm sure the author will have not objections to its inclusion and   
 that many users will be happy to have it available out of the box of  
  next gimp 2.6

 DOWNLOAD LINK HERE

 ###

 then i will like also propose a replacement for a old script add   
 border that is now in Filter/decor

 add border script is quite limited while there is another similar   
 but more flexible , offers more useful options but does not look   
 more complex to users (and even avoid some problems that the   
 default script may create)

 problems are : is easy overlook the fact that the script will   
 increase the imagine size
  (..i replied to several messages of users surprised that gimp   
 enlarge imagines without asking
 first time was very hard trace the reason of the problem...was ,as   
 in the other cases ,that overlooked side effect of the script  the   
 root of the problem )

 in the alternative script i propose that is a option, and when   
 evaluating a option come more natural evaluate its obvious  side   
 effects,

 other simple but useful added options are

  blur the frame (user may chose blur amount )
  use gradient instead then a solid color
  merge down -don't merge down the frame layer

 Also for this i'm not the author, but i know he will have no objections

 ###
 I suppose 2.6 is  in features freeze, but even then i believe   
 add/replace those few lines of code should  not be a problem

 Also because  first script will solve the problem of a basic feature  
  missed and increase usability

 ,the second seems a better replacement for a old and somehow tricky script

I do miss 'Apply Image', which allows you to either:

1. Apply any RGB/CMYK/spot channel or all RGB/CMYK channels from one
image to another (if they are the same size) using any of the blending
modes available (multiply, screen, etc).  Selections remain active
during the procedure.

2. Apply any channel to any other channel within the image using
available blending modes. Selections remain active.

It's a nice feature that opens up a lot of possibilities, esp if you
are working with spot channels.

seems a good alternative

 my main objection on this alternative is that is not ready but a project to be 
realized in a future and that will require some developer offering his time to 
realize it,maybe subtracting that time to more relevant task.
while the script is ready and was already tested by many

This approach would seem 

more intuitive and would not entail an additional menu command.

Not sure if that will be a advantage the addition of new option there may be 
easy overlooked while a menu command as copy visible and add as new layer is 
so clear that i believe can't be misunderstood

Avoid to overcrowd the menu is good but i see this as a basic feature that many 
may search ,if so may be better clearly labeled in the place where most likely 
will be searched 
as in the Edit menu,after copy and copy the visible

( Nevertheless a extra option for merge layer.should not harm .but again will 
be a work to be done by someone in a future ,while the script-fu  is ready)

PS 
About add border i never noticed a 3d effect or others that are not present 
also in the alternate version.but i will check better

It's a dialog, that lets you blend channels from one or two images.

Here's one tutorial in which two images are blended (at the beginning):

Here's a general description of the dialog with screenshots:

Thanks for the pointers. I had a look at this and some other tutorials
and to me this looks like going back to GIMP version 0.54 where you had
to use a dialog to blend images together simply because GIMP at that
point did not yet have layers.

I might be wrong, but it appears to me that everything that Apply
Image does can be done using layers. It's just another way of using
layer modes and it seems quite akward to use an extra dialog for that.
