Render Technological Image

FyerEgg — Thu, 05 Nov 2009 17:15:52 +0100

Based on the set edge, pixel ammount, color and brightness, this script-fu generates a layer that looks techno.

Here is an example of what it makes...

You can find it when you create the image window...

Exact Aligner

vtries — Fri, 02 Oct 2009 08:06:05 +0200

This script brings 2 pictures to an exact overlap.
The pictures must be in 2 different layers of the same image.
Get the layer 2 with 50% transparency. This makes both pictures visible in one projection.
You have to tell the script, which 2 points have to overlap. Therefore you stroke a path with a path tool in the image including 4 points. Point 1 will be aligned with point 3 and point 2 will be aligned with point 4.
The points build one path. So you can just click the 4 points consecutively.
More description is in the file.

Thanx

Create Paired Layers of numbered files into single psds

ErichT — Fri, 07 Aug 2009 18:29:57 +0200

This is a simple script that combines multiple paired files into single multi-layered psd files in the same folder.

A little history: I beat my head against the wall for quite a while trying to make this script using the file-glob and batch functions, but could never get it to work due to ubuntu's random file manager which made it impossible to correctly pair my numbered files. Anyway, I created this because I had a couple thousand paired images each numbered and in two different file formats (jpg and tif) that I needed to put into single psd files. For example, I had background images and colormaps that overlay the backgrounds (1001.jpg was one background and 1001.tif was the colormap, then 1002 was a different background and colormap, etc.) and I wanted to put them into the same file so I could edit them together easily at a later time, hence the creation of a psd with the bottom layer the jpg and the top layer the tif.

I imagine anyone can modify this script to take any different file formats easily. It would take a little more time to edit this script to take the pairs from different folders or use a different naming scheme, but hopefully this could give whoever a start.

I am by no means an actual programmer or have much experience with scheme or any programming language, so this script may not be the best way of doing this.

Paste separate selection as individual layer

GandalftheGray — Sat, 13 Jun 2009 21:36:19 +0200

This is my first script.
It is needed to the competent cannon http://registry.gimp.org/node/60 script.
I you have more that once rectangle selection area. You can use this script to copy on active layer any selection area and set him as individual layer.

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'.

Export All Layers to Anime Studio Project (ANME)

ja227 — Thu, 18 Dec 2008 02:17:07 +0100

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 2.4.2 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. You can also rename the ANME file to something besides the base image name, but if unspecified, the ANME's name is the same as the image name, minus the extension.
I have not tried it on, nor did I design it for, layers with masks. I also did not design it to handle any types of blend modes besides normal mode.

Wavelet decompose

marcor — Tue, 18 Nov 2008 17:18:44 +0100

This plugin losslessly decomposes a layer of an image into layers of wavelet scales. This means that you can edit the image on different detail scales (frequencies). The trivial recomposition of the image can be done by GIMP's layer modes so you can see the results of your modifications instantly. Among the applications are retouching, noise reduction, and enhancing global contrast.

Wavelet scales

An image can be transformed into a set of wavelet scales. There are detail scales and one residual. The detail scales contain the image details of a their scale size. This means that scale 1 contains only image details of the smallest scale. Scale 2 details are larger and scale 3 details even larger (and so on). This image illustrates this:

This plugin computes these scales losslessly and creates a new layer for each one. The recomposition is the addition of all scales which is done by GIMP using the grain merge layer mode. You can then paint the scales with your favourite tool, using (128,128,128) as neutral colour (for the details, not the residual). Values below neutral darken, values above lighten. The most straightforward thing to do is to use the paintbrush tool with the neutral colour and use different brushes and opacities. That way you erase details.

Skin retouching

The problem with skin retouching is retaining skin detail but erasing spots and such. However, one might want to keep freckles in the face (see image below). Achieving this is very difficult when operating in the normal image space. The skin details such as pores and hair are very small, spots and pimples are larger. If you erase the larger spots (with an airbrush for example) you hide the skin details inside it. With wavelets you decompose the image into scales of different detail size. To state it simply: One scale will contain the skin details like pores, other scales contain spots. They are rather nicely separated. Look at the image with the wavelet scales above. The first scale contains pores and freckles (it's a small image indeed) and the second and third one the spots. The problem is not separating the details from the spots anymore but finding out in which scales they lie. This image (taken by +psv) has been edited using wavelet decomposition. One could have erased the freckles easily, but this natural face is beautiful because of them.

Noise reduction

The human eye easily distinguishes noise from image detail. Computers cannot. By decomposing the image into wavelet scales you can decide for yourself which parts are erased and you get the most high quality result. For example in image regions which are out of focus you know there can't be any image details on the pixel size (they are just blurred). So you can pick a brush and erase wavelet scales 1 and 2 in such places. Image details of greater size are untouched by this as you will notice.

Local contrast

If you change the residual scale instead of the detail scales you can change the brightness of the image or global contrast without affecting local contrast. This means that you can get image details back out of dark image areas in full local contrast. This works for overexposed areas as well. However clipped image details (beyond white or black) cannot be restored.
