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 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

Nuvola Tools!

2013-03-01 - Minor revision upgrade:
updated the nuvola-tools-install-commands.sh to work with the more recent Debian Wheezy (debian testing)
You will be able to use nuvola tools on a more recent system and it's likely to work in Ubuntu too!

NUVOLA TOOLs offer advanced grayscale cleaning and processing functions for your scans,

automates removal of shadows, dust and toner particles typical of less than perfect prints ,

screentones removal through automated shape and topology recognition and much more!

Layer via Copy/Cut


GIMP 2.8 Python Plugin.
Copy and move the selected area to a new layer in the same position.

This function is similar to the functions with the same names in Photoshop, and more powerful. Unlike them, it can copy/cut content, not just from one layer, but also from the layer groups.
In Photoshop, this is not possible :)

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

Export Sublayers for Gimp 2.8

based on http://registry.gimp.org/node/26292, I added export for sublayers in gimp 2.8. I'm not a python programmer, so I'm happy when someone would code a more clean version, but it works anyway..

Show Layer Information

This small script shows some information related to the current selected layer. This info includes:

- The layer's name
- The layer dimensions (in pixels)
- The layer offset respect the origin of the whole image (in pixels)

You can go to View->Layer info menu option to show the layer information window. The window stays on top, so the user can switch between the different layers of the image to inspect their values easily.
