Cropping Image

[rinaldop]

Happy Holidays Everyone!

I am back with another problem. Is there an easy way to crop out each image individually? I did one by hand.

Thanks

I keep forgetting you are using Gimp 2.10 ...thus... using an old script (attached - goes in your user scripts folder)

(1) A bit of pre-editing, use the crop tool to trim top / bottom / sides
(2) Add guides where you want the split.
(3) Image -> Slice Using Guides to make new images.
(4) File -> Save ALL As  using that old script (find it bottom of File menu).

   

Edit: For those using Gimp 3. Almost the same except use the batcher plugin to export all open images.

WOW Thank you for the quick reply! I just don't do much graphic work so I did not keep up with the versions I will install v3 now

Gimp 3 has some nice advanced features ...but... I am a great believer in using what you are comfortable with. Also Gimp 2.10 supports very many scripts and plugins which have yet to be implemented (if ever) in Gimp 3.

Ah, thanks for the advice.

So, my intention is to take a bunch of screenshots like the one above and crop out all 4 card images for a FAQ for the game Demeo x Dungeons & Dragons: Battlemarked (GREAT game BTW)

Thanks to this thread I can do them one at a time by hand but is it possible to use BIMP to batch it?

Maybe, with many caveates:

This is using one of Ofnuts Gimp 2.10 python plugins ofn-tiles.py from http://sourceforge.net/projects/gimp-too...s/scripts/
That then depends on your OS, Windows ok, some linux Gimp 2.10 versions do not come with python 2.7 support. MacOS - I do not know.

Are all the screenshots identical to the example you posted. For the sake of this example I am assuming they are. ofn-tiles.py is a bit picky about sizes, the width in pixels has to be divisible by four.

Thus, in BIMP it might go like this:

   

(1) Crop to trim off the un-needed edges. Use the "other Gimp procedure" not the BIMP version.
(2) The ofn-tiles.py comes with two entries, using the rows columns entry
Set the output folder, probably best to copy/paste from your file manager or carefully enter the path. ie I am using this /home/rich/Project/split/
Set the output file name template. You can change the output format. png is default for jpeg something like this: {imageName}-{column1:02d}.jpg Set 1 row , 4 columns.
(3) BIMP need a destination to dump the original (cropped) images.

As a test to check working, your posted image as coloured duplicates, outputs like this:

Looks like I have everything covered, Gimp 2.10, Windows 11, all the screenshots should be identical.

I will give it a try and let you know how it goes.

I must say I am always amazed at the things you guys can do with Gimp!

Thanks Rich!

Rich, your instructions were so detailed that I wanted this to work on the first try but I tried it many times with no success. The worst part is when I did both manipulations at once like your example my output directory is empty.
The batch cropping works perfectly so I then tried using the directory with the cropped files as the direct input to the ofn tiles script as one manipulation and although I did get output that time the output images were identical to the input. I even reinstalled Python 2.7 though I didn't reboot.  Let me show you my work. I will say that this is rather humiliating
