I am new to gimp's scripting and would like to automate the rectangle selection tool by defining the position and size using a script. Afterwards, I would like to extract the selection, 'paste as new image' and save the image as a png file without compression.

It would be nice, if you can give me some hints, how to achieve this. Maybe, something similar exists already!?

I am sorry that I cannot produce a script but why not put the question to http://forum.meetthegimp.org/ there are some very knowledgeable and helpful script writers there.

Hi,

I've attached some code here - it's from a similar plug-in that I modified to (almost) do what you want. It will need some work for it to be useful, but it should be pretty easy to follow and also modify to suit your needs. I've only given it the barest amount of testing with gimp 2.6.6 on linux, but it should be cross-platform in theory (as long as Python+GIMP is correctly installed).

Note that the gimp.file_png_save() call is most likely using compression - check the procedure browser for the right parameters.

Also, I chose to duplicate/crop/save/destroy rather than select/copy/paste new/save/destroy - I just found that method simpler.

Hope this helps and good luck! Chris

Hi to both,

thanks for your help and thanks for the script! I tried the attached python script
by using execfile("script.py") from the python-fu console. Unfortunately gimp (2.6.7 on ubuntu) crashed. Do you have a hint, what I am doing wrong!?

Yes - that was originally written as a plug-in (place in ~/.gimp-2.x/plug-ins, chmod +x, it registers as 'File->Export Area').

I think this code should work in the console - either via execfile or typing/pasting it in.

You should be able to do this using David's Batch Processor. It will let you define a fixed region to crop from an image and save as png, then apply that to multiple images. No scripting necessary. Google DBP.
