Based on Guillermo Maldonado Rule of Thirds, the script adds Golden Ratio guides to the image.

Automaticly copies the image and insert this. The script creates a Layer-Mask and makes a part of the insert layer invisible.
It's great to have a part of the original image on the top, because than you have a very well comparision.

If you have any suggestions for improvement contact me.

I hope this example conform your requests:

In the "Layer mask" mode the dominant is balanced with a mask, such that your whites remains whites.

This is a Python plug-in, written initially in Spanish by Mr Javier Pacheco, which from an image creates a standard complete month calendar. It has been translated in English and modified by me to try for more flexibility in the design of a standard calendar. Seven layers (plus an optional one) are added to the image to control the three main elements mostly below it on the page : background, calendar box and month-year info.
The options in the dialog are:
° Separation between the image and the calendar box
° Width of the calendar box relative to the image  read more »

Windows binary for this new plugin by Arel Welgan.

Source has been fixed for Windows compilation by Samj. Plugin no longer crashes under Windows.

Please note that all comments below, prior to Nov 28 2009 are related to another build not to this
that seems working well with RGB and RGBA images

Extract colour-match.exe from the ZIP archive and copy it to your c:\Documents and Settings\[user name]\.gimp-2.6\plug-ins\

(As Windows compilation by Samj was perfect, I kept it in the archive. Mine was several bytes larger...)
