How to make API in GIMP?

I was using Opencv to make APIs about image processing in visual studio 2010 and then use them in Android. now i started to use gimp and gegl library to do the same. but i dont find any reference about how to do.

i just want to know how to load and image using gimp and then manipulate the image and finally get an output. what are the functions? i saw some codes for gimp plugins. but the main() function is not present the开发者_如何学JAVAre. like in opencv i have something like this..

int main(int argc, char** argv)
{
}

i tried to use the code from this link how-to-use-gimp-drawable-set-pixel. i am supposed to get a red pixel. but i cannot compile it in visual studio. i get this: Native' has exited with code 1 (0x1). i dont understand what i am missing.

The best thing is to go into the Gimp IRC-Channel. You can find more infos about it here: http://wiki.gimp.org/index.php/Users:Beginner_Developer%27s_FAQ

It may be that Gimp# can help you here.

This is a Plugin that provides an C# API for Gimp and can be found at Sourceforge.

This it's own description from the site:

GIMP# is an API wrapper around GIMP, written in C#. However, it's not just a wrapper. It also adds a thin layer which adds C# specific features, like iterating through a collection. An example of this is an iteration through the guides of an image.
