Image Tiler -- tile single or multiple images into n*m grid with options

tileimages.scm -- Put n*m same sized images onto one image in n columns & m rows with optional padding, grid lines, bounding box, rounded corners and feathered edge.

If there aren't n*m images passed, the last image is repeated until n*m positions are filled.
This is useful for just passing one image, which will be tiled for all n*m positions.
If there are more images passed, only the first n*m are used.

Islamic Design

This function get a value (WIDTH) from user and draw some regular lines.

Save-mod

When editing an image you can use this script to export the image under the old filename with an extension of '-mod' added with just one click.

Grass and sea texture maker

This is a script that transforms a black and white simple drawing into a map like image with grass and sea. I tested it only on my machine, and it take several seconds to run and create a reasonable looking figure. All my tests where tried on a 500x500 image with 200x200 dpi resolution.

My machine (the only one I tested this on) is Lenovo edge. It has a i3 processor (don't remember the exact model) and 6GB of RAM. I run Ubuntu 13.04 and gimp 2.8.4 on it.

How to use.

Color to Mask Pro

A tool for masking out single-colored backgrounds.

Features:
* The two-step operation allows easy manual corrections
* Masks background color and (optionally) drop shadows
* Four operation methods: Difference, Value, Hybrid (soft) and Hybrid (hard)
* All thresholds are soft
* Edge compression
* Color spill correction (semi-manual)
* Optional Pre-blur reduces mask noise and artifacts
* The "Ignore channel" feature eases removal of background with the color similar to the objects

Free-Form-Bokeh

This script consists of 2 separate plug-ins, free-form-semi-auto-bokeh and free-
form-auto-bokeh.
Both allow you to simulate the bokeh-effect (the out of focus effect which causes
point-like light-sources to appear as disks).
The "free-form" means the user must determine the size and the shape of the bokeh.
This is done by creating a selection before running either plug-in.
This selection can be placed anywhere on the image.
This means you can simulate a partially closed aperture with for instance a selection

concentric-fill-selection

This plug-in fills all the selected parts of an image from the outside in with 2 colours
or 1 colour and a transparent band. The filled selection will be placed on a transparent
layer above the active layer.
The number of bands is user defined in the number of iterations, if however the
selections is totally filled, the process will stop before the number of iterations
being given is reached.
To totally fill a selection, choose a very high number of iterations.
The width of each band can be increased or decreased by a given amount of pixels in

Balance colors through samples indicated as gray.

This little script was inspired by "GIMP tutorial - advanced color correction using sample point and curves" which nicely describes a method to get the color balance of a drawable right.
It expects an active path. If it's not there it exits unceremoniously.
The average RGB values of a 5 pixel radius area around the points in the path are taken and from these color adjustment curves are invoked with the aim to equalize them and thereby get the color balance right.

Move Layer To

Layer -> Move To
Moves the active layer to the specified coordinate on the drawing Canvas.

Tested on Gimp versions 2.6.11 and 2.8.2. Let me know if you find it incompatible with other versions.

Frequency and/or Color Separation

One of the secrets of great image manipulation is to separate images into components. Frequency separation is often mentioned, breaking the image into so-called high-pass and low-pass layers. The high-pass layer separates out the sudden changes in an image and fiddling with this layer can enhance sharpening or even out blemishes. The low-pass layer can be used for smoothing out color transitions. Portrait photographers use this extensively for smoothing skin and removing spots. There is no native Frequency separation tool or filter built into gimp.
