Five nice and useful plugins for Gimp
One of the big advantages of The GIMP is the fact that it can be easily extended with new functionality. So with sufficient addons (particularly plugins), you can achieve a lot of functionality found in other editors. Last month i did show a collection of useful plugins for Gimp and today i will show you again another five nice ones that hope will be useful for you: 1- Burnt Paper : This plugin creates a burnt-paper effect. 2- Batch color contrast: The script enables you to do two image adjustment operations to all images in a folder: 3- MathMap : An image processing application 4- Drawable Multiplication : Generate multiple copies of a drawable into the image where the drawable is 5- Divide Scanned Images.
1- Burnt Paper
This plugin creates a burnt-paper effect. It uses your selection as the original outline of the paper. It then creates an old looking piece of paper that is burnt around the edges and overlays the current layer atop this paper.
Here is an example of its output:
The image was created from a text layer and a selection that was larger than the text area:

2-Batch color contrast
|The script enables you to do two image adjustment operations to all images in a folder:
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).
You can either create new files or overwrite the old ones. It is not possible to create new folders using Script-Fu, so new files are saved in the same folder, but with a ‘_’ prefix added to the file names.
Unfortunately there is no preview, so you will have to open one of the images in GIMP and find suitable settings for colour balance and brightness/contrast before plotting them into this script.
This is my first script, and my first week as a GIMP user (in other words: I am not a pro!), therefore it might not be perfect, but hopefully it can be of help to someone.
The script appears in File->Create->Misc

What the script looks like:
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.
- More advanced users can combine filters intuitively in the Composer, as pictured above.
- For expert users MathMap provides a simple but very efficient programming language. This is the core of MathMap and the language that almost all MathMap filters are implemented in. MathMap can be used as a GIMP plug-in as well as a command-line tool. It is distributed as Free Software under the terms of the GNU General Public Licence.

The Mathmap Gimp plugin is available for Windows and Linux (for Mac there is a older, standalone version ) For more info, documentation screenshoot , download,source code and video presentation visit :
4- Drawable Multiplication
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.
If the drawable is a layer-mask, the script will operate on the layer to which such mask belongs; if the drawable is a channel, the offset parameters will be ignored.
Besides creating new drawables, this script also returns a vector whose first element is the identifier of the starting drawable, whereas the identifiers of the duplicates occupy the other elements. Hence, when the script is called as procedure inside another script, such vector helps to trace every duplicate.
Once installed, you can launch this script from the image menubar through ‘Edit -> Drawable Multiplication…’.
The two screenshots appended hereunder show how this script can help you to get three copies of a layer representing Wilber and spread them all along a diagonal of the image.
Here is a GIMP session containing the image and the dialog box of the script with its parameters set to appropriate values:
This is the final result:

5- Divide Scanned Images
A script that will detect multiple images within a single image, crop them, optionally straighten them, and save them out with incrementing filenames+numbers. It was developed to aid in separating photos scanned on a flatbed scanner as one “image”.
There is a big discussion thread over at gimptalk on this: http://www.gimptalk.com/forum/viewtopic.php?f=9&t=36438
The script also provides a batch mode to process a while directory of scanned images pages.
Note that the straightening will only work if you have the deskew plugin installed: http://www.cubewano.org/gimp-deskew-plugin/
