There were a few anaglyph 3D images that I wanted to view as cross-eyed stereo pairs (I don't have glasses handy). I started doing the manipulations by hand to convert them from anaglyphs, then got tired of doing it manually.
So, I wrote a quick script-fu to do it for me. This will take a 3D Anaglyph image (red/cyan), and create a stereo pair (monochrome) for you...
As part of writing the next part of my tutorials on B&W conversion, I needed to quickly decompose an RGB image into different grayscale channels based on useful channels from all the color modes (RGB, CMY(K), LAB, HSV, HSL, YCbCr).
It was tedious doing it by hand, so I wrote up this small script to automatically decompose an RGB image layer (active) into each of the color decomposition modes, and to keep the most useful to me for B&W conversions.
GIMP 2.8 Python Plugin.
This plugin allows you to duplicate layer, layer with mask, or layer group from one image to another.
1. Extract "duplicate-to-another-image.py" from .zip archive to the ".../.gimp-2.x/plug-ins/" directory.
2. Make sure that the extracted file is executable.
3. If you are already running GIMP, close and reopen it.
This script adds several tools under Script-Fu - BgMask: "Extract background...", "Mask against background...", "Average linked layers...", and in BgMask 0.2 there are also "Extract background manually" and "Mask adjustments...". It can be used to mask moving objects/characters from animations with still background.
BgMask 0.3 introduces a new tool, "Blend Edges" which allows your masked objects to blend seamlessly into different backgrounds. Also, it improves the denoising algorithm of Mask Adjustments and adds a "Smoothen via paths" option.
