How to use an external command to make an edit of pic in the gimp and then return the result to the stage in a plugin or script.

Example in shell script.:

magick label.gif matte
( clone -shade 110x90 -normalize -negate clone -compose Plus -composite )
( -clone 0 -shade 110x50 -normalize -channel BG -fx 0 channel -matte )
-delete 0 swap -compose Multiply -

The command above (imagemagick app) create a gif and i want put back in gimp stage. May be other simple option or application, but i need of return the edited back to gimp. Python, script fu? Thanks so much.

If GIMP will take stdin, then pipe from ImageMagick to GIMP using the GIMP XCF file format.

magick label.gif  matte 
(  clone -shade 110x90 -normalize -negate  clone -compose Plus -composite ) 
( -clone 0 -shade 110x50 -normalize -channel BG -fx 0  channel -matte ) 
-delete 0  swap -compose Multiply XCF:- | GIMP -

There is a shellout.py Gimp plugin floating around from which you can borrow code. Typically:

• you export the layer to a temp file (if you work on the whole image, you likely have to do a pdb.gimp_layer_new_from_visible())
• call the executable with subprocess.Popen() and a list of arguments
• load the result as a new layer with pdb.gimp_file_load_layer()
