Colour Match

bleg — Wed, 18 Nov 2009 07:49:16 +0100

Easily map colours from a source colour to a target colour. Very effective for matching skin tones across images or between people.

Relatively quick (but not earth shattering). It doesn't work with grayscale or indexed images. Has preview, works with selections and layers, etc. Very, easy to use, and quite useful for portraits or recolouring graphics.

A demonstration: Lenna's face is mapped to the colour of the feather on her hat. This was done by selecting a colour from her face, then selecting a colour from the feather.

If you have an x86_64 version of GIMP 2.7 on linux, bunzip2 and move the colour-match file to your plugin directory:
bunzip2 colour-match.bz2
chmod 700 colour-match (Make it executable)
mv colour-match ~/.gimp-2.7/plug-ins/colour-match

To build it type: gimptool-2.0 --install colour-match.c
You will need libgimp-dev, and libgtk2.0-dev packages if you didn't build GIMP from source.

The algorithm is based on the relative color remap plug-in by Lars Clausen ( http://registry.gimp.org/node/5442 ).

Watermark

laurentiu — Mon, 09 Nov 2009 06:32:28 +0100

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.

Install in the plug-ins GIMP directory. Make sure the file is executable or GIMP will ignore it.

To process a file via command-line:

The parameters are source image, "save as" filename, opacity, text, font name, font size in points.

LayerGroups subsystem for Gimp

LayerGroups subsystem for Gimp

New version 1.0a, uploaded June 30, 2009

LayerGroups is a comprehensive layer groups subsystem for GIMP. It allows the creation of groups and subgroups of layers without limitation, based on the layer names. It allows you to hide or show many layers simultaneously, link or unlink them, rename them, delete them, duplicate them in the same image or to another image, move them up or down in the layer stack (raise or lower) in relation to a specific reference layer, generate external image files (for example png, gif, jpeg etc) from each of the layers of the group, and several other operations.

The selection of layers for the group can be enhanced with filters, for example only layers that are linked, or contain a specific keyword in the name.

LayerGroups contains a built-in help system that works two ways: when you are on the GIMP menu system with the mouse above one of the menu options you get a multi-line window with help and instructions on how to use the specific functionality and when you are in the dialog box where you enter the parameters, there is a menu that you can open to read the same help text. This help system is prepared in such a way that it can be easily translated into other languages, like French, German, Spanish, Portuguese, Dutch, etc.

LayerGroups has been thoroughly tested in a project with images containing hundreds of layers where most of the mentioned layer group functionality was required. As a useful spill off, the LayerGroups script contains many generic script-fu functions that could be very useful in other scripts for GIMP. It has been tested under Windows XP and Vista with Gimp Portable version 2.6.6 and under Ubuntu Linux, Gimp version 2.6.6. To install the script, copy the script file "mig-gimp-layer-groups.scm" to the scripts directory and from GIMP execute the menu option Filters->Script-Fu->Refresh scripts. You should get a new main menu option labeled 'LayerGroups' between 'Filters' and 'Windows'.

New version 1.0a: features

The new version 1.0a has a built in option to allow the LayerGroups subsystem to be placed under the 'Layer' menu of the Gimp image window. By the default you get a new 'LayerGroups' menu entry directly in the Gimp Image window. If you change the script file at line 35 - which contains the text '#f' in the first 2 characters - (change the 2nd character in that line from 'f' to 't') the 'LayerGroups' menu entry will become a sub-menu entry of the 'Layer' menu entry. Use any text editor to edit the 'mig-gimp-layer-groups.scm' file. For example, under Windows you can use NotePad to edit the file. Make sure the saved file maintains the extension '.scm'

This new version contains some bug corrections and new functionality. The new functionality includes 'delete linked layers', 'reverse the stack order of a layer group' and 'reverse the stack order of the currently linked layers'.

Radial Copy (True Polar Array)

pkotronis — Thu, 16 Apr 2009 19:58:25 +0200

Note: I accidentally posted this as a plug-in first. I've now correctly posted it as a script.

This script allows the user to select an item in the image and to create a true polar array of the selected object (think kaleidoscope as opposed to Ferris wheel seats). It is useful for creating objects that possess radial symmetry.

The user can control:
-center point of rotation
-distance from the center point to the objects in the array
-starting angle for the rotation
-angle between each copied object
-number of objects in the final array.

Some experimentation may be required to get the result you want, as I made the script rather flexible.

Select the exact outline of what you are using to create the array. Using a standard rectangular selection box will potentially crop pieces of the array as it rotates.

I've attached a sample image and an image of the values that I used to achieve the effect.

Layer to selection

kiwibird — Sun, 08 Mar 2009 18:09:01 +0100

Why this is not already a menu item I do not know.

Does what it says, makes a selection to match your layer.
