This is a python script that creates a new image of a color wheel on a transparent background. I wrote this script so that I could have an image of a color wheel to use as a color selector inside a C++ program. I wanted a color wheel image that was not copyrighted. This script was inspired by KEMPER BARKHURST. He wrote script-fu-kbColorWheel.scm. I converted his script to python and modified it to remove the lines between each hue.
After running through the tutorial, I decided to write another version of the plug-in with a few options.
This plug-in requires Python. If you have the 'Filters->Python-Fu->Console' menu item you are all set. If not, install Python support for GIMP.
The plugin can be found under Filters>Artistic>Cross-Process. Don't forget to make the plugin executable.
Reduces high ISO banding, blue haze and somewhat chroma noise. Intended for images produced by Olympus gear on higher ISO settings, could be useful on images from other companies. It's fast, but alters colors, lightning of the scene in a dodge-burn fashion. New version adds Gaussian blur on Y, Cr & Cb channels, which can be used separately.
When saving script please remove ending '.txt' extension, and make sure script is marked as executable.
This python plug-in strokes or fills the current selection and creates a 3D glossy effect with a dropped shadow. The color, brush, lighting, and shadow are adjustable through the initial dialog. Use the Filters/Light and Shadow/GlossyStroke 3D menu.
Note: Depending on the color, adjusting the opacity of the "volume" layers can give better results.
It is my first GIMP plugin, so any comment, criticism or improvement is appreciated. The 3D effect parameter could certainly be improved.
12/16/10 - Version 1.2.0
- The light direction is now opposite to the shadow.
A python conversion of my script-fu Line border script (http://registry.gimp.org/node/118). This version uses python-glade dialogs. It allows to create smaller and much clever input dialog and integrate much more functions. On other side, due to missing support of glade dialogs from Gimp, there is not possble to run this script in batch mode.
