Sorry, you're right (although I was as clear as script-fu itself...) GIMP just opens the typical pop-up window saying that there was an error in the procedure, without saying which kind error was it). I don't have 2.6 installed here, sorry for not being more precise. I expect no error, of course. > Perhaps we need to add gimp-layear-has-mask then. Or at least gimp-layer-remove-mask to do nothing if no mask exists. Strange that the script-fu routine worked in 2.4: the routine gimp-layer-get-mask returns the mask, it is not boolean, so it shouldn't really work as a conditional... > Until then you could use gimp-plugin-set-pdb-error-handler to take > over the error handling in order to suppress the warning. But then the script will not work in 2.4 (could not find that procedure in 2.4).

It really doesn't help to say that something is broken if you don't explain in more detail what happens and what you expect to happen.

No. In python scripting this is possible using software like 'xdotool', but not in script-fu (because there is no command to shell out and run another command). After looking at your script, I suggest you also use '--no-data' commandline parameter to GIMP to cut down on memory usage and startup time, since you don't appear to use any brushes/gradients etc in your script.

Now I have my script running, It's a simple script that produces the table-mirror effect apple does, but is it possible to check whether the interface is available or not, I mean if gimp is running with -i mode (no interface). Also, the script resizes the original image, is it possible to change the actual zoom from inside the script? how ?

[Gimp-developer] script-fu problem in 2.6
Hi, I have a script-fu that worked fine in 2.4 and it's broken in 2.6. It had a conditional to apply the layer's mask if it exists. This is what it read: (cond ((gimp-layer-get-mask SharpenLayer)(gimp-layer-remove-mask SharpenLayer 0)) ) Now it is broken. How do I tell script-fu 2.6 to apply a layer mask (if it exists)? I was unable to find something like a boolean gimp-layear-has-mask, and gimp-layer-remove-mask returns an error if the mask does not exist. Thanks!!

There is no "paste-as-new-layer" function provided as such by the PDB interface (though there is a menu command for that) and so you must perform a couple of separate functions to achieve the same result. You do not need to set up a current layer, but you need to perform a 'gimp-floating-sel-to-layer' after your 'gimp-edit-paste'. This will result in a new layer at the top of the layerstack -- unlike the menu command, which places the new layer above the active layer -- and therefore it does not matter which layer (or drawable) is active at the time the paste is performed. If you instead wish the resulting new layer to appear just above the current layer then you will need to make note of the current layer's position (using 'gimp-image-get-layer-position') and lower the pasted layer accordingly (using 'gimp-image-lower-layer' the appropriate number of times). ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
Re: [Gimp-developer] Using GIMP from my own program
Ok, I made it work, I just replaced newlayer for newimage in the
gimp-edit-paste call and it worked.
But pasting into the image should work, shouldn't ?, do I have
to set up a current layer or something ?

Re: [Gimp-developer] Using GIMP from my own program
Well, following all advices I decide to make the plugins I need for gimp,
and use it in batch mode, this way plugins will be available for everybody.
But my first attempt is not working fine, I'm coping/pasting the following
code into the script-fu console, and I get a black image as glam-out.jpg
with correct size, could you tell me why ?,
(this is a test that should make an image which is double in height than
input, and the upper half size has the input copied as is and the lower
half size has the input copied rotated 180)
(let* (
(image (car(gimp-file-load 1 "/home/pablo/glam.jpg"
"/home/pablo/glam.jpg")))
(width (car (gimp-image-width image)))
(height (car (gimp-image-height image)))
(newheight (* height 2))
(newimage (car(gimp-image-new width newheight RGB)))
(newlayer (car (gimp-layer-new newimage width newheight RGBA-IMAGE
"Copy" 100 NORMAL-MODE)))
)
(gimp-context-push)
(gimp-image-add-layer newimage newlayer -1)
(gimp-drawable-set-visible newlayer TRUE)
(gimp-selection-all image)
(gimp-edit-copy-visible image)
(gimp-rect-select newimage 0 0 width height CHANNEL-OP-ADD FALSE 0)
(let ((floating-sel (car (gimp-edit-paste newimage FALSE
(gimp-floating-sel-anchor floating-sel)
)
(gimp-selection-none newimage)
(gimp-rect-select newimage 0 height width height CHANNEL-OP-ADD FALSE 0)
(let ((floating-sel (car (gimp-edit-paste newimage FALSE
(gimp-rotate floating-sel FALSE 180)
(gimp-floating-sel-anchor floating-sel)
)
(gimp-file-save 1 newimage newlayer "/home/pablo/glam-out.jpg"
"/home/pablo/glam-out.jpg")
(gimp-context-pop)
)
