Hello,

I'm a newbie here sorry if the questions are stupid but I spent hours reading a lot of stuff about Gimp Scripts but can't find an answer to some questions.
I'm currently using the Script-Fu console before I write a real script to get used to the commands

I need to cut the same selection on 1000+ pictures, resize the selection and paste it on other pictures
First I saved my selection to a path and exported the path to a file

I managed to make this command work after importing a saved SVG path :
(gimp-path-to-selection 12 "MyPath" 0 FALSE FALSE FALSE FALSE)

1) I'd like to use a command/script to import my saved SVG file
commands such as :
(gimp-vectors-import-from-file image filename merge scale)
(gimp-path-import image filename merge scale)

But no matter how I write the filename, I get "no such file or directory"
Do I need to put the file in a specific folder ?
I tried to write "c:\tmp\path1.svg" but it doesn't work

2) Using the console, is there an easier way to refer to a picture than to look at the ID of the picture ?

Thanks

1) Two things you could try for your filenames:

"c:\\tmp\\path1.svg"

or

"c:/tmp/path1.svg"

2) No - you have to use the ID

Thank you very much, the second format works perfectly !

Do you know which procedure corresponds to the "Scale Tool" (scale layer, selection or path)
Is it "gimp-item-transform-scale" ?

In this case, how do I refer to my selection ? (this procedure needs an "item")

Yes I think gimp-item-transform-scale is what you want and gimp-image-get-selection will get you the selection ID

Kevin

I just tested gimp-item-transform-scale : it scales the selection but not the actual picture inside it
Am I missing something ?
Thanks

That's because a selection is just an area - it's not connected to any of the layers in your image until you use it to copy/cut/paste etc from/to a particular layer.

Rather than trying to second guess what you are trying to do (which happens far too often here), how about you explain the process you are trying to implement.

Kevin

Sure, here you go :

I'm trying to make game cards

I have a lot of 1024X768 pictures and I need to cut the exact same zone each time to get the character, resize it (680X980) and paste it centered on a background picture (size 822x1122)

A picture should be more explicit than my poor english



these pics are just examples, I'm not using street fighter stuff for my card game

That's a good description.

So after making your selection, you need to copy that area from the first image...

So use gimp-edit-copy which will copy the area described by the selection

Then you can paste it as a floating selection (gimp-edit-paste) into the second image and then re-scale the floating-selection, which you already know about.

You may need to move the floating selection and then you will have to anchor it.

If you write your script in Python (which is somewhat simpler than Scheme), then most of the API will use the complete "objects" and not the IDs, plus it is usually a bit simpler to get at data. For instance, making the 5th layer of the image invisible can be as simple as:


Choose wisely

It will be much faster to:

- Duplicate the image with the character
- Crop the image around the character
- Enlarge the canvas
- Import the background layer

Using the clipboard in scripts is a bit slow, and momentarily kills the clipboard for other applications in the system, so it's best avoided.

The clipboard does seem to be a bit slow, though I can't imagine why that should be so (I will need to investigate further). As to killing the clipboard, one can use as many named clipboards as one wants, and never affect the "global buffer" clipboard (see the "Edit->Buffer" submenu or the *-named-* PDB procedures).

passenger57, here is some code for you to peruse. The challenging bit is to transfer the selection in the template to the source images (to copy the character). My code copies the selection to a (named) buffer, which is then copied to a channel in the source image and loaded as a selection (GIMP does not allow pasting directly into the selection mask).

There are other ways to do this, such as your use of paths, but I wished to emphasize that a selection is just a grayscale drawable that itself can be saved, copied, scaled, etc.

Note that my code uses the global buffer, which is generally a bad idea for a script (scripts should typically used named buffers); however, since you would be running the code in batch mode, there is no chance of the code interfering with what a user might be doing.
