I'm very new to Python, let alone pygimp. I have a decent amount of experience in java, renderman, and a few other VFX based scripting languages though. I'm trying to get scripts that I'm finding here on the forums to work in my Gimp build, but only the template package from the pyGimp registry has shown up in my menus. I am on a Windows XP box running Gimp 2.6.8, Python 2.6.7, I have GTK+ installed with pyCairo and pyObject. I can see Gimp read through and check the plugins when i start it, but then they do not show up anywhere, even if I copy the register from the template plugins that are working.

I have been trying to implement the plugin here:

viewtopic.php?f=9&t=985

Its not exactly what I need, but Id love for anything to show up really. I have a Python-Fu in both plugins and file/create. Am I missing something? Do I need to compile? Any help would be greatly appreciate! Thanks in advance!

Assuming we're talking about the script I wrote for Photocomix and that you have copied the code into a file.

Where have you saved the file you created? and what name did you give the file?

If it has registered correctly you should have a menu item like this:

To be sure you have Python enabled, can you select Filters>>Python-Fu>>Console ?

Hi Kevin, I do have Python-Fu>>Console, but I do not have contributed.

I saved the files in C:\Program Files (x86)\GIMP-2.0\lib\gimp\2.0\plug-ins

as test_v001.py

Thanks

Somehow you've lost all the indenting. For Python this is VERY IMPORTANT

Many have tried and failed to break GAP.

Have fun with it.We have many tutorials by ccbarr that are just awesome.He really knows GAP's in and outs.
