Copy Color Channel

Current Release: v1.0.0 - MIT LICENSE 

©2024 John Riggles

This Aseprite extension allows you to copy a specific color channel (i.e. the red, green, or blue part) of the currently selected cel to a new layer. You can also choose to copy from the composite color channels, cyan (green + blue), magenta (red + blue), and yellow (red + green).

Requirements

    This extension has been tested on both Windows and Mac OS (specifically, Windows 11 and Mac OS Sonoma 14.3.1), but should also work on Linux

    It is intended to run on Aseprite version 1.3 or later and requires API version 1.3-rc5 (as long as you have the latest version of Aseprite, you should be fine!)

Features & Usage

    To use this extension, go to the Sprite menu in Aseprite and then select "Copy Color Channel..."

Then you can choose the color channel you'd like to extract, or click "Copy All Channels" to create a new layer for each channel.

Checking the "Retain Transparency" box (on by default) will also copy the alpha values from the selected cel into the new layer.

     If you find this extension useful, please consider donating to support further development! ♥
