Script-fu inverse-visibility-active-layer

Hevan53 — Thu, 12 Nov 2009 12:59:26 +0100

This script inverse the visibility of the active layer. It is very useful because you can give it a short cut and use the mouse only on your image!

Hevan53 — Thu, 12 Nov 2009 12:54:56 +0100

This script create a yin-yang figure inside an image. In the package there are : script-fu-yin-yang.scm and all-visible-or-all-invisible.scm (because the first script depends of the second script).

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...
Script-Fu -> Render -> Tech

(Note: This is my first Script-Fu)

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.

Comic Book Filters

Comic Book filters for Gimp. Will turn any photo into a comic book style image. Great effect for creating graphic novels, or comic strips.

Palette Generator

krypt — Thu, 30 Apr 2009 15:07:17 +0200

New version:1_3
Add to palette black, gray and white by default.

New version:1_2
Save palette bug fixed.

Version:1_1
Adjust light of scheme work fine (I hope!)

It generates palette by following the harmonic schemes of color: monochromatic, complementary, triadic, tetrad and analogous.
Options:
- you can choose between the digital wheel (RGB) and the real wheel (RYB);
- you can choose whether to use the color "web safe" or not;
- you can see in real time in a preview page the combination of colors;
- you can save a Gimp or Inkscape palette.
Required python libraries: :
- GrapeFruit-0.1a3
INSTALLATION: copy file gimp_palette_generator.py to the standard place for plugins (folder "plug-ins").

See: http://krypt77.altervista.org/index_gimp.htm

Cross-stitchify v2.1

w_nightshade — Fri, 20 Mar 2009 15:30:15 +0100

Someone on an email list I belong to asked about ways of making a counted cross-stitch pattern from a photo. There are commercial packages that do this, but it seemed like something GIMP could do, and I wanted some Python practice.

Attached is a zip file containing the following files:

cross-stitch.py - Python script for converting a photo to a cross-stitch pattern
floss.html - an HTML document listing available cross-stitch floss colours by numbered index, common name, RGB and hex values (culled from http://www.stitchstuff.com/dmcrgb.htm)

I used the Photoshop tutorial found here as my starting point. The script performs the following operations:

Pixellates, adjusts brightness & posterises according to user settings
Scales down the pixellated image to increase performance
Checks each colour of each mosaic tile, and performs "best matching" colour exchange against the palette of available floss colours
Scales up pixellated image for next operations and for readability
vAdds grid in new layer
Adds text labels for each colour with floss' index number
Creates a text file listing all floss needed, and in what quantities

It appears in the menus under Filters > Decor > Cross-stitchify... It takes quite some time to run as I need to iterate through each tile of the image twice, and any interruption during the label phase can crash the script, but the output is quite good. The entire image can be printed for use as the pattern, or just the grid if printing in B&W.

UPDATE: version 2.0 - added creation of text file with list of what colour floss, and how many stitches of each, are used. Also allowed for greater range of mosaic sizes to accommodate wider range of images.
UPDATE: version 2.1 - added OS check: win32 opens text file, other OS displays message with path to file.
