Color to Alpha

This product provides a Blender setup designed to isolate line art by removing white backgrounds from sketch images. It utilizes a shader configuration paired with linear rendering to cleanly extract linework without producing a white halo effect along the edges. The resulting output is a transparent grayscale image.

The included blend file contains an embedded Python script that automatically adjusts the scene's render dimensions to match the source image. This script also ensures the image is set to the correct non-color color space before processing.
