hello sir/mam, we r students of final year engineering studing in national institute of
engineering,mysore,karnataka,India.

sir we r doing a project on pattern recognition in image processing.we have chosen linux as platform.we came to know about GIMP and GIMP-PLUGINS. sir we have some questions reguarding this 1>what r plugins & how can they be used in our project?
2>where and how to write plugins to handle images and extract pixel values after selecting a particular area in an image, and how to compile and run them in GIMP? can u plz help us about this sir.
3>how to compile a plugin and load a plugin? 4>how to write a plug-in to load an image into the image viewer of gimp and access(pixel values) a selected region

Hi!

First a general remark. When writing to this list, please use proper English spelling and conventions. Capitalize letters where appropriate, don't use abbreviations like "r" and "u", etc.

Plug-ins are programs that GIMP runs that can interact with the GIMP. A plug-in can call the functions of GIMP and of other plug-ins and so create effects and manipulate images in certain ways. Most of the Filters under the Filters menu are implemented using Plug-ins.

2>where and how to write plugins to handle images and extract pixel values after selecting a particular area in an image, and how to compile and run them in GIMP? can u plz help us about this sir.

For compiling plug-ins you should make use of gimptool. There's a plug-in template available at:

ftp://ftp.gimp.org/pub/gimp/plugin-template/

which you can start from, and you can take a look at the existing plug-ins in the GIMP distribution or in the Plug-ins registry (http://registry.gimp.org/) for ideas how to do things.

3>how to compile a plugin and load a plugin?

To load it put it in one of the GIMP's plug-in paths (e.g: $HOME/.gimp-2.3/plug-ins/)

4>how to write a plug-in to load an image into the image viewer of gimp and access(pixel values) a selected region

What does the image viewer has to do with a plug-in? You can load images using the gimp_file_load() PDB function. Code to access its pixel values can be found under plug-ins/ in the GIMP distribution.

I think this is a request for advice on how to create a file loading/saving plug-in (registering the handlers for file type etc...). AFAIK there is no template for this (wasn't there an enhancement request for this?). It should be possible to use existing plug-ins as an example, though.

HTH, Michael

The only purpose of the plug-in template is to help people that are trying to create complex plug-ins to get the build system right. It is complete overkill for 95% of all plug-ins and definitely for any file plug-in I can think of.

The API reference at http://developer.gimp.org/ is what we should point developers too. The plug-in template only comes into the game if the plug-in becomes large.
