A downloadable Aseprite script

SnapPalette.lua is a Lua script for Aseprite that snaps the RGB values of the current sprite's palette.

What it Does:

SnapPalette.lua will snap the color values to either the nearest number, the number rounded up, or rounded down.
If a range of colors within the palette is selected, the script will only affect the currently selected colors. Otherwise, it will affect all colors in the palette.
You must have a sprite selected for the script to work.

Install instructions

How to install:

In Aseprite, go to File > Scripts > Open Scripts Folder. This should open an Explorer window at <Aseprite program folder>/scripts.
Copy the file SnapPalette.lua to this folder and in File > Scripts select Rescan Scripts Folder.
The script should now be available for use.

Instructions:

While editing a sprite, either select a color range in the palette or leave it as is.
Go to File > Scripts > SnapPalette and select SnapPalette.
In the dialog box, select the value we will use to snap the colors. Think of it as a grid, but instead of pixels, for colors.
Select whether we will round to "nearest" (the closest multiple of the value), round up (the next multiple of the value) or round down (the previous multiple of the value).
Press "apply" to snap the colors.
