One of the secrets of great image manipulation is to separate images into components. Frequency separation is often mentioned, breaking the image into so-called high-pass and low-pass layers. The high-pass layer separates out the sudden changes in an image and fiddling with this layer can enhance sharpening or even out blemishes. The low-pass layer can be used for smoothing out color transitions. Portrait photographers use this extensively for smoothing skin and removing spots. There is no native Frequency separation tool or filter built into gimp.
Hi this is my second Script-Fu and it seems a few people liked it so i thought i would post it here at the registry.
It's a SCM script so it will go in your scripts folder.
Just open a image and select the layer you want to work on and go to Filters>Artistic>Embroidery Stitcher.
The script is non interactive, that is to say it just runs with no adjustments (for now), and should work on any layer or image.I may add a stitch width adjustment later.
This script helps create simple rotating animations.
It asks for the desired number of animation frames (between 4 and 24 frames in increments of 4), and generates the corresponding number of layers each containing a rotated version of the image's background layer.
A choice of animation motion (circular and pendulum) is provided.
It has been tested in Gimp 2.6.11 on GNU/Linux and 2.8 on Windows XP.
Released v1.11 on 2012-07-02.
* Added pendulum motion
* fixed issue from lingering test code
AnimStack is a collection of tools to simplify creating animations in GIMP. It makes heavy use of Layer Groups, introduced in GIMP 2.8.
A simple example of a problem this script might solve: you have an animation, but you want to put some text on top of it. Normally you would have to add text to every frame manually, but with AnimStack this task is completely automated. AnimStack is perfect for post-processing your GIF animations and adding various simple effects to them.
Does exactly what you expect it to do. Every top-level layer group is merged (careful: only visible layers in each layer group are merged). The layer tree becomes completely flat. Why is this useful? Well, I made it because it is impossible to convert an image to Indexed mode or export it as animated GIF if it contains any layer groups. And layer groups are extremely useful for animated GIFs. It's a conundrum! And this script helps automate the process somewhat.
