This plugin is by Bert Hinz. As his web site seems to be down, I'm archiving it here. It says it's "free software" (looks like part of the GPL Licence) so I'm assuming this is OK. Description from the script:
This plug-in is a demonstration for python programmers of Gimp plug-ins. It displays almost all the built-in GUI widgets for parameters to plugins. It shows what a plug-in dialog can be using what is built into PyGimp. An alternative to using what is built in, is to use a Python GUI library such as pygtk.
Motivation: the documentation seems sparse for PyGimp GUI widgets. This is example code.
It does nothing to Gimp images, it's not for users, just for beginning programmers.
This plug-in is designed for batch watermarking and resizing of image files. It lets you choose the directory which contains the images, the file extension, the font, the copyright text and the options associated with the processing. Useful for photographers who upload a lot of photos on the web and don't want to watermark every single file individually. The resulting images contain between one and four instances of the copyright text (selectable as an option).
Take the active (selected) palette and create an image containing the colors and their names. Requires python.
- Font: pick the font for the name listing
- Size: size of each color
Tested with 2.6 and linux, but should work cross-platform.
TODO: it's hardcoded to a minimum of 200px wide - I should change that to something more reasonable. Some nice additions would be bg and text color selectors, and possibly some layout options (spacing, columns, etc.)
Creates two new layers: one containing the Luminance, and the other the Chroma information in the form of a Grain Merge. Optionally, it will color-enhance (maximize saturation in) the Chroma layer while still keeping it luminance-neutral.
This allows you to do noise-reduction and sharpening on the two layers separately.
