Batch crop images... but keep centered

This is a small script for batch crop images and keep centered.

Frequency and/or Color Separation

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.

Move, Scale, and Rotate using paths as reference

This is a collection of four scripts which help with aligning layers for HDR and mask workflow, as well as simply scaling, moving, or rotating layers.

Embroidery Stitcher

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.

Rotation Animation

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

True PseudoGray

A script-fu implementation of the Pseudogrey encoding as presented originally by Rich Franzen, and brought to my attention by gimpchat.com user lylejk in this thread.

I've written up a blog post as well detailing the method and how it's derived.

AnimStack: animation tools for GIMP 2.8

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.

Flatten all layer groups

Image > Flatten Layer Groups

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.

Pixel Dot Mask

This creates a simplistic version of the early newspaper/print halftone (https://en.wikipedia.org/wiki/Halftone) dot look. It is based upon a manual method described at http://www.reddit.com/r/GIMP/comments/uggfq/help_how_to_dot_raster_an_im...

Version 1.1.1 -- updated 2012-06-20: Fixed issue running script in GIMP 2.8

Split and join images

This an improve version of "To slice and merge images" you can split your images in any number of rows and columns and join them again later.

Improvements:

  1. The splitted images have an Alpha Channel (transparency)
  2. The images names have sequential numbers (image1, image2...)

Bugs Fixed:

  1. The resultant images don't have the previus extension in their names
  2. The files aren't overwrited anymore

Thanks to "Anonymous" for the Alpha Channel and Giuseppe Conte

The aplication is installed in Filters->ATG
