: Best way to create a gif out of a tiled image I have a very large image ( >500 Mo !) containing a series of smaller images of the same size, in mosaic, as follows: [ 1 2 3 ] [ 4
I have a very large image ( >500 Mo !) containing a series of smaller images of the same size, in mosaic, as follows:
[ 1 2 3 ]
[ 4 5 6 ]
[ 7 8 9 ]
But in my case, there are hundreds of them.
I would like to make a gif of all the images, in the right order (1 to 9 here). I thought I could use GIMP to do this, but the only task of extracting the images looks complicated, so it may not be the way to go.
How should I do ?
thanks

There are scripts such as this or this that will chop the image and export the tiles to files.
Then open an empty image of suitable size, and do File>Open as layers (you can select all the files in one shot).
If necessary there is even a transpose script to exchange/line columns in case the first script takes them by columns first.
Use ImageMagick. This is exactly what the tool was made for.
Or to be more specific use the montage command of ImageMagick is for making montages. The montage documentation includes many examples.
And the reverse operation of montage is documented under crop. This should cover all your needs.
