GIMP Plugin Registry

Imprints a non-intrusive faint text watermark sparsely repeated over the entire image. The watermark is meant to be visible upon close inspection without disturbing the viewing of the image.

The watermark visibility can be fine-tuned by changing the opacity of the watermark layer.

Contains an image plugin that operates on an open image and a batch
plugin that requires the filenames for the source and modified images.

Requires Python.  read more »

Watermarks a bunch of photos with the watermark file specified. Files are output to the ./WM subdirectory in the format specified.

The watermark is applied with a difference mode overlay in the bottom right corner. Let me know if something should be parametrized.

I run this script like so:

gimp -i -b '(python-fu-watermarker RUN-NONINTERACTIVE "{PATH-TO-FILES}" "{PATH-TO-WATERMARK}" "jpg")' -b '(gimp-quit 0)'


Generates watermark by bump mapping the selected layer with the specified input text. Uses the bump mapping technique found here: http://www.gimp.org/tutorials/The_Basics/
