current release: v1.0.0
- Initial Release!
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).
This extension has been tested on both Windows and Mac OS (specifically, Windows 11 and Mac OS Sonoma 14.3.1)
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!)
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.
You can download this extension from itch.io as a "pay what you want" tool
