GIMP Plugin Registry

Helps with the viewing and editing of gimp scripts. The command section should be modified to accommodate your flavor of scheme.

--> Back up or rename the original lisp.properties.
--> Save this lisp.properties.txt file as lisp.properties
--> Then place this lisp.properties file in the Scite/Scintilla directory.

The script enables you to do two image adjustment operations to all images in a folder:

1. Individually adjust the color balance in shadows, midtones and highlights
2. Adjusting the Brightness and Contrast

You choose a folder with a folder browsing widget, you can also specify the file extension of the files you would want to change(useful if you have non supported files in the same folder).  read more »

In order to understand how this script works, we must focus on the selection mask, that is the channel related to the selection (you can view it either by activating Quick Mask or by saving the selection as a channel). Referring to this mask, the script eliminates every area that is composed from non-white pixels and is completely enclosed by a fence of white pixels; since the elimination consists in filling such areas of the mask with white, the corresponding holes of the selection will disappear.  read more »

The purpose of this script is to generate multiple copies of a drawable into the image where the drawable is. It is helpful especially whenever you have to get several duplicates of a drawable, because like this you can avoid repeating the 'Duplicate Layer' or 'Duplicate Channel' commands of the GUI so many times. Moreover, this script allows to displace the duplicates of a layer along both horizontal and vertical directions through the offset parameters, so that you can easily achieve a sequence of equidistant layers which should be otherwise obtained step by step.  read more »

I just notice that MathMap one of the better Gimp Plugin is not listed here.
To present it i just quote its developer Mark Probst
---------------------------------------------------------------------------------------------------------------------------------------    
MathMap is an image processing application that works on several levels:

* Without any prerequisite knowledge about image processing, one can use any of the more than one hundred filters that come bundled with MathMap.  read more »

The script makes a pencil drawing from a photo. It's very easy to handle.
The original tutorial can be found here: http://www.gimpusers.com/tutorials/making-a-pencil-drawing-from-a-photo....
Here you can see a little example:

This script creates nice shapes in Gimp. The model is a layer/path it will be duplicated a few times and these copys will be moved and/or rotated.
The coolest effects can made with a spline (from a path). In the new version you can choose if you take a path or a layer. The interest here is, that you don't lose on quality.

So, here's a little guide:
1. Create a path and make it visible.
2. Start the scirpt (Filters/Shapes) and make your settings.
3. Go to paths dialog, right click -> Merge Visible Paths
4.  read more »

This plug-in is designed for batch watermarking and resizing of image files. It lets you choose the directory which contains the images, the file extension, the font, the copyright text and the options associated with the processing. Useful for photographers who upload a lot of photos on the web and don't want to watermark every single file individually. The resulting images contain three or four instances of the copyright text (depending on the orientation of the image).

At present, the script does not perform any sanity checks, so don't give it single-pixel images to process :).  read more »

Quantizes (reduces color count) and traces outlines or centerlines, into a new image. Optionally creates paths for the outlines or centerlines. Also can be used to generate an SVG file for an image.

Calls autotrace (a separate program that must also be installed) to do the tracing (to SVG, a vector file format) and then imports the SVG back into Gimp.

Writing the plugin was an exploration. I explored why tracing to SVG was in programs like Inkscape but not in Gimp. I explored simplifying the daunting interface to autotrace.  read more »

I've seen an very interessting video (http://meetthegimp.org/episode-127-octave-sharpening/) about the so called "Octave Sharpening" I've never heard. So I started searching for some information about it and found also 2 other sharpening methods (http://www.varis.com/StepByStep/sharpen/Sharpen.html).
The PDF tutorial (second link) shows the function with Photoshop so I implemented the scripts for gimp and wondered how effectfull they are.

Here is version 1.0.  read more »
