Crop out multiple fixed size boxes

[SReza_S]

Hello, I’m new to gimp and I need to crop out multiple 1600x256 px parts out of a 4160x1968 px image.

So far I’ve managed to fix the crop box size in the Tool Options, but now the problem is that I have to export the cropped part manually and it’s very inefficient.

Is there any way to do this operation in bulk? for example I select multiple crop boxes and export all of them at once.

Note that the crops are not aligned, and I need to freely choose them.

Instead of cropping you can copy/paste them to new layers (Ctrl-C, Ctrl-Shift-N) (the rectangle select tool has the same “fixed” option) and then use a script to export all layers (many available, including my own ofn-export-layers.

Alternate method:

• Make sure there is an alpha channel (Layer > Transparency > Add alpha channel)
• Make your multi-rectangle selection
• Select > Invert and Edit > Clear (or Ctrl-I + Del) so that your rectangles are now surrounded by transparency
• Use my [ofn-extract-objects script]((Ofnuts' Gimp Tools - Browse /scripts at SourceForge.net) to extract them all in one shot.

I’m using GIMP v2.10.30.

I think I’m on the right path

But even though I placed the ofn-export-layers-cumulative.py in ~/.config/GIMP/2.10/plug-ins and restarted the GIMP, I still don’t have the File ➤ Export layers accumulations.

Figured it’s because the python support is not working in my Gimp. I don’t have Filters > Python-fu menu, but Python 3.10.12 is installed on my system.

Gimp python support requires Python 2.7.x, which is unfortunately deprecated and is dropped by many distros as a defaults install, while the distro’s Gimp version is made Python-less.

There are several ways to reinstate it.

I believe this PPA lets you install Gimp 2.10 with Python support. Python 2.7 is still available in the repos AFAIK.

There are also an official flatpak version with a built-in Python, as well as several AppImage. But you have to live with the implied sandboxing.

There’s no problem with installing multiple versions of python. I installed python 2.7 by sudo apt install python2.7 and the python support is not still working.

NVM, my bad to come back at GIMP after dozens of failed attempts. Uninstalled it for good.
