Scripts to manipulate gifs by drag-and-drop in masse
Requirements: Python
PIL, NUMPY for image manipulation
In cmd.exe
pip install pillow
pip install numpy
Some bash to launch .sh scripts
gifsicle to unoptimize gifs (often source of errors in brute manipulation)
Add gifsicle's folder to your PATH

Download this repository (Clone or download → Download zip) and put it somewhere (unzip it). Open the folder and keep it around so that you can drag-and-drop images onto the scripts.
Most of the scripts work with simply drag-and-dropping one or several files on them.
Calling scale_image.py scaling_factor filename
resample\ X4.sh EarthPrincess.gif
→ 
redux\ nearest\ 4.sh EarthPrincess_X4.gif
→
You can rename the redux/resample/reduce bash files to change their scaling factor.
You can drag-and drop multiple files on them.
x → 
You can only drop two files on this script
The second file can be a folder of .png
Creates a file sourceimage_palette.sh on which you can directly drop several images that will all be recolored.
The new script will call transfer_palette.py sourceimage otherimage. Good if your images come from different folders!
You can drag-and drop multiple files on this script.
You can drag-and drop multiple files, including folders of .pngs on the script generated by this script.
This script will retrieve the .pngs in the sourceimage\interpolated_frames local folder and stich them into a .gif while using sourceimage as a palette source. Just drag-and-drop the source gif onto the script if it is in the same folder as the folder that DAIN created.
Used when working with folders generated by #DAIN-App.
A variation of the previous script that will also automatically pixelise the X4 upscaled output. Great timesaver with all the steps involved!

You can drag-and drop multiple files on those scripts.
Calling change_background.py r g b filename
bg_col\ 255\ 0\ 0.sh march_new.gif
→ 
You can rename the bg_col rgb files to change the color they apply.
bg\ empty.sh march_new.gif
→ 
bg\ fill\ empty.sh march_new.gif
→ 
You can drag-and drop multiple files on those scripts.
bordline_1.sh pendulum.gif

bordcrop_0.sh pendulum.gif
→ 
bordcrop_1.sh pendulum.gif
→ 
You can drag-and drop multiple files on those scripts.
You can change the number in the name to change the border size.
You can drag-and drop multiple files on those scripts.
RETIME 20.sh EarthPrincess.gif
→ 
You can copy and rename the RETIME files to change the duration they apply.
RETIME 2d1.sh EarthPrincess.gif
→ 
You can copy and rename the RETIME files to change the fraction that is multiplied to the existing durations.
If the frame amounts are different, it will duplicate them (as long as it's an integer number).
If the sizes are different, different centering methods will be used.
STACK_gifs.py EarthPrincess.gif gloria_robot.gif
+ = 
STACK-V gifs.sh EarthPrincess.gif gloria_robot.gif
+ = 
You have to drop several files on those scripts.
The order in which they are stacked is: the one you clicked on first, then by folder order.
If the order in which things are stacked is not up to tastes, can easily re-shift the squares by inputing the divisions (width, height) of the source and the result.
rearange_gif.py 1 3 3 1 Examples/PolarBear_A.gif
→ 
You can copy and edit the separations in the filename to change the way the images are split.
Legacy format for a game called Fantasy Online where players could participate in asset-creation.
spritesheet_to_gif\ 3x4.py PolarBear.png
→
Will call gifsicle with the right parameters.
Often, when there is an optimisation bug for a gif, you'll want to unoptimise it (and maybe set its background to a solid color).
It will happen often with PIL.
