GIMP Plugin Registry

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

Offsets all layers by half. Image/Half_Tile_Offset Useful when creating a tilable texture. Just press Alt+I,O and you can start editing the image-edge seams.

A workflow-friendly fast alternative to going around every layer and selecting Layer/Transform/Offset... / Offset by x2,y2 / OK

Usage:

Let's say we have this 256x256 crop:

Creates a new spritesheet (animation frames) from the layers of an image.


1) To install, copy SpriteSheet.scm to {GIMP-HOME}\share\gimp\2.0\scripts\SpriteSheet.scm
2) Either close Gimp and re-open, or simply select menu: Filters > Script-Fu > Refresh Scripts
3) Load your images via File > Open as layers (select all the images you want to in the spritesheet)
4) Optionally re-order your layers to determine ultimate order.  read more »

This is an update for Gimp 2.6; below is the original description:

This is to use if you have Anime Studio (v5), and want to convert your layered image into an character on that program. The script works on GIMP 2.6 and Anime Studio 5, and that's all I've tried it on. Each layer is saved as a 24-bit PNG, using each layer's name as a base, and referenced in the output ANME file. You can choose the output folder for both the ANME file and the image files.  read more »

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!

Creates a new layer with a grid, rotated 45 degrees, to help you choose corners for cropping.

Move the grid until a line intersects a feature in your image, then crop so that the grid line meets a corner of your cropping rectangle. You can then use the grid to choose the opposite corner, but make sure you don't change either of the sides of your original corner.

FX-Foundry/Color/Separate Luminance...

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.

Update (23-Jul-2009):
Noticed that highly-saturated colors exceed the ability of the grain-extract/grain-merge to handle without clipping the color, so I have made the excess color get folded into the luminance layer.  read more »

FX-Foundry/Photo/Enhancement/Maximize Local Contrast...
Like Stretch Contrast, but instead of using the minimum and maximum pixel values from the entire image, uses the minimum and maximum in the vicinity of a pixel to compute its new value. Takes a while to run, but really brings out textures. Result is a Grain Merge layer that adjusts values of the original image.

This filter operates on the visible image, not on a layer or selection.  read more »

L*C*h (L*a*b* in polar coordinates) color selector module.

Just type "make install" to install this module (You don't need to rebuild the GIMP.) .

It generates a ruler to embed into geographical maps. It allows to customize scale, colors and other things.

The main options are: Step(px) and Step(unit). They define the scale of the rule. Each "px" a step is drawn, representing "unit" kilometers, miles or meters, etc.
