Sample implementation of a new GEGL op
I tried to implement the blur operation in GEGL. The algorithm is same as of the blur plug-in in GIMP. The patch file for GEGL operation and the blur.c file for the plug-in are attached below. Kindly let me know if there is any mistake in my implementation.

Hi,
I tried to submit the patch in bugzilla, but i was unable to create new account there for not getting any email containing confirmation link. I mailed bugmaster@gnome.org also, but in vain.
Sample implementation of a new GEGL op
Ya i am also unable to create an account on bugzilla. I already made the plugin a day back. But have been waiting in vain for the confirmation mail from bugzilla. I want to ask my mentor Mukund to kindly tell me what to do in this case.
Any help from any one is most welcome
Thanx in advance

The gnome.org people can take a while to respond at times. Have patience.

Did this code work for you? Were you able to use this inside GEGL to perform a blur?
You can help me review this code if you clean it up and comment it.

I've revised my code. It compiles and runs successfully. The patch is attached below. If still there is any mistake, kindly let me know it.

Hi,
I changed the code little bit. I placed the blur.c file in gegl-0.1.2/operations/common folder & followed these steps to compile GEGL.
1. configure
2. make
3. make install
it compiled successfully. But I don't know how to check whether it runs or not. Please help me finding this out & cleaning it up. Sorry for replying late.

I overlooked the option in GIMP to run GEGL operation. Now I have checked it, and it works.

I've added comments in my code. If still there is anything to do, please let me know.
