I am assisting in making a wiki for an old game, and we ripped the avatar GIFs from the games shop and want to have a catalog of them. What I need to do is to crop all the borders which are identical from 3,170 GIFs and maybe make background transparent.
I haven’t used python in years, but I managed to cobble up something that almost works as a single image test, only issue is that it crops and outputs only the first frame:
from PIL import Image
if __name__ == "__main__":
input_loc = "AvatarShopImages/80001.gif"
output_loc = "Output/80001.gif"
im = Image.open(input_loc)
im = im.crop((4, 4, 94, 94))
im.save(output_loc)
If it looks weird, it is because I copy/pasted some code and edited a lot out of it.
Open GIMP
Go to “File” > “Open” and select your GIF.
Select the “Crop Tool” from the toolbox.
Adjust the crop area to your desired size.
Click the “Crop” button.
Go to “File” > “Export As” and choose GIF as the format. Save your cropped GIF.
FFmpeg
Use the following command to crop the GIF, replacing input.gif with your GIF’s filename and specifying the crop dimensions:
ffmpeg -i input.gif -vf “crop=w:h:x:y” output.gif
