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

This script lets the user pick a number of images. Then tries to packs the images on as few pages as possible, respectin their print size.

The algorithm is not optimal, but does a fairly good job.

Helps with the viewing and editing of gimp scripts. The command section should be modified to accommodate your flavor of scheme.

--> Back up or rename the original lisp.properties.
--> Save this lisp.properties.txt file as lisp.properties
--> Then place this lisp.properties file in the Scite/Scintilla directory.

I don't like the look of the existing beveling scripts so I wrote one up. It iterates shrinking selections to generate a bump map. It will use (in preferred order) the current selection, the alpha of the active layer, or the whole layer for the shape. The result is generated as a new layer set to hard light blend mode. It has:
- Inner and outer chisel/carve
- "Softness" parameter controls how hard/soft the heightmap bevel is
- "Effect Blur" parameter performs a post-bevel masked blur to make the chisel look more "puffy"
- Option to keep the bumpmap

Draws one of five types of predefined spirals, or lets the user modify the power parameter. The formula is:

r = a + b * theta ^ n

r - radius
a - growth factor
b - multiplication factor
theta - angle
n - power factor

The predefined types are: Archimedean (n = 1), Fermat (n = 1/2), Circle (n = 0), Lituus (n = -1/2), Hyperbolic (n = -1). If you choose a predefined type, the power factor you input on the form will be disregarded.

A simple detail enhancing/sharpening filter based on my simple bilateral code. It is essentialy a low precision version of the detail enhancement stage of some local tone mapping algorithms.

In non technical terms this is basically the anti surface blur. It takes a surface blur as a base layer, compares it with the original image and magnifies the differences. It brings out textures and makes skin look pretty horrible.

It will appear under:

Filters->Enhance->Enhance Details...

Windows version provided by Francois_C. Updated.

A surface blur filter based on a simplified version Porikli's O(1) bilateral filter.

Unfortunately due to the nature of the algorithm memory overheads can be severe. This filter uses a tile based implementation, which limits overheads to about 64mb.

On the plus side it is reasonably fast and scales well with filter radius.

When installed it should appear under filters->blur->simple bilateral

There is a mercurial repository which will be kept up to date with the latest code on my web site. This can be accessed with:

Alters image to have gradually fading overlapped borders when tiled. Like The GIMP's filter Make Seamless, only not as strong an overlap. To achieve this, the image size is reduced. The overlap amount can be chosen by the user. The script can be accessed through /Filters/Map/Make Weakly Seamless...
