UPSIZE: An image upsizing plugin featuring two modes.
1. Smooth (IBFNBQH): Image upsizing with Interpolatory Box Filtered Natural BiQuadratic Histosplines. [This is the default option.]
2. Sharp (EANBQH): Exact Area image upsizing with Natural BiQuadratic Histosplines.

This plugin was written by Nicolas Robidoux and Adam Turcotte at Laurentian University in Sudbury, Ontario, Canada.

Cropp a webpage automatically

You define a dictionary type directly inside the plugin script stating the layers and the area of the image you want to cropp, and you can give a resize factor (variable newsize) for the whole image. You can choose between opening all created cropped images in gimp or saving them.

Just edit the default images dictionary to your needs or test the script on the example xcf file available at

You should have some basic python knowledge to use this script!

Palette to Image

Palettes Menu -> Palette to Image

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.)

Have fun ;)

Export Layers as PNG

File->Export Layers->as PNG

Prompts for a folder to save PNG files. Pretty straightforward. *Requires* python!

Should work with 2.4.x through 2.8.x. Will NOT work with some 2.7.x versions and the 2.8 RC1! 2.7 users should move on to current git and 2.8 RC users should upgrade to current 2.8.

- toggle to flatten (remove transparency).
- toggle to save only visible layers
- now saves as filename + layername and special characters are removed
- toggle to remove layer offsets
- toggle to zealous crop each PNG before saving

Removing Timestamp

This script removes the timestamp imprinted on photos by digital cameras.
A friend had more than 400 photos with such a timestamp so I tried to get rid of it in a fast way. The script is a little quick'n'dirty but in most cases it's doing the job just fine. Better than I thought in the first place...

The procedure:

  1. select the area with the timestamp (manually but optional)
  2. select the color of the timestamp in your selection
  3. add alpha channel to layer (transparent background)
  4. remove the timestamp

G'MIC : GREYC's Magic for Image Computing

The G'MIC plug-in for GIMP proposes a set of various filters to apply on your images, including artistic effects, image denoising and enhancement algorithms, 3D renderers, etc.. It is a quite large plug-in, integrating a lot of different effects.

Loader for NASA/ESA PDS/EDR images

This plugin loads NASA/ESA PDS/EDR images.

PDS/EDR format is the image format used by NASA Planetary Data System
and by ESA Planetary Science Archives. PDS images from various space
missions are available at and


Separate+ is the plug-in package that provides some useful color-management functions for the GIMP.

RGB to CMYK conversion / Softproofing plug-in (improved version of Alastair M. Robinson's "Separate" plug-in)
RGB to RGB conversion / Profile management plug-in
separate_import (bonus)
CMYK TIFF import plug-in which generates the pseudo-composite image

Current release: version 0.5.8 released at November 9,2010

Layer Effects

This is a series of scripts that implement various layer effects:

  • Drop Shadow
  • Inner Shadow
  • Outer Glow
  • Inner Glow
  • Bevel and Emboss
  • Satin
  • Color Overlay
  • Gradient Overlay
  • Pattern Overlay
  • Stroke

Some effects can have contours (a.k.a. curves) and noise added to them. Effects can either be applied on a separate layer, or be merged into the active layer (which in some cases gives better results).

Tested with GIMP 2.4.2.

Liquid Rescale

This plugin aims at resizing pictures non uniformly while preserving their features, i.e. avoiding distortion of the important parts.

plugin example

For example, you may turn a normal picture to panoramic without stretching the content.

The plugin supports manual feature selection, and can also be used to remove portions of the picture in a consistent way.
