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 ).

Scale and move the layer to cover the canvas. Just another "shortcut" script for a commonly used action...

Export Layers as PNG

File->Export Layers->

Prompts for a folder to save PNG files. Pretty straightforward.

Tested in 2.6.1 on linux and 2.6.6 on XP.

Layer Informations

Script-fu that displays the active layer name and x, y, w, h

Range Selection Script

The range selection script is a tool for easy and automatic creation of selections and layer masks. The selections or masks include all parts of the image that are situated within a defined range of tonal values, colours, saturation or edges. Selections can be based on one of 16 channels. For detailed instructions and several samples have a look at the attached manual.

To Split Image

GandalftheGray — Sun, 14 Jun 2009 12:36:53 +0200

This is my alternative for 'To slice and merge images' (see http://registry.gimp.org/node/14953).
If you haver use this script; download too http://registry.gimp.org/node/60

Two script for:
1. Set width and height rectangle to split and set as separate layer
2. Split in rows and columns and save any rectangular portion in the new layer

Layer to selection

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

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

Extended Split Tone

Lucidlook — Tue, 27 Jan 2009 16:12:39 +0100

This script creates two sets of layers - one for highlights and second for shadows.
You can then adjust the tone by changing of opacity each R,G,B layer.

Launch from: Script-Fu -> Color -> Extended Split Tone

Find and Replace Text

cr33dog — Mon, 01 Dec 2008 00:23:50 +0100

Find and Replace Text on all text layers.

Find: text to search for
Replace: text to replace with
Replace All: replace every match [YES/no]
Case Sensitive: match case [YES/no]

The plug-in is found at Edit->Find & ReplaceText...

Tested on Ubuntu 8.10, GIMP 2.7 (SVN).

Could use some further testing, esp. on other platforms.
Matching is done using Python's re.sub function - so special character should work (\n, *, +, etc.).

TODO:

- add option to only replace on current layer
- add a pop-up to report the number of changes made (re.subn())

Merge Visible with Layer Mask & Alpha

Snake-Arsenic — Wed, 27 Aug 2008 05:59:49 +0200

Merge visible using the active layer transparency to create a mask, visible layers below are discarded.

This can be useful in 3d applications to preserve texture maps that belong in the alpha channel by using the bottom layer's mask to hold the information.

Appears in /Image/Merge Visible with Layer Mask & Alpha of the Image window.
