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...

2-Dimensional Gradient v. 1.2

Charles Belov — Sun, 26 Apr 2009 16:24:26 +0200

2-Dimensional Gradient (2DG) produces a new layer containing a gradient that changes in two dimensions. People using non-English-language GIMP installations are encouraged to upgrade to this version.

9 sample gradients follow (collected into a single image):

It can generate gradients from corner colors, edge gradients and/or the existing image. Options may be manually set, randomly created or duplicated from an existing 2DG layer.

The layer options used are stored in the created layer name. The option duplication feature depends on this name.

Once installed and Script-Fu refreshed, 2DG can be found under Filters > Render > Pattern. It will be active if there is an active RGB image.

If you have a selection active when you run this script, the gradient area will be a rectangle sized to the selection. Non-rectangular selections will be supported through creation of an edit mask, but the gradient will be based on a rectangle.

Due to looping logic, the wider or taller the image, the longer it will take to render. So you might want to try gradients on a smaller image first, then reproduce the gradient on a larger image if you like the results. The "Current 2DG layer - all settings" option supports doing this action after trying other gradients or after closing and re-launching GIMP.

Options:

Option source:
Choose whether to enter all of the options yourself, or to generate some of them randomly.

Current 2DG Layer: If you have an existing 2DG layer selected, you can also choose to duplicate some of the options from the existing 2DG layer. This is handy if you want to replicate a smaller test in a larger area.

If you choose Random - all options or Current 2DG layer - all options, there is no point in setting any of the other options manually as they will be ignored (except for the checkbox to allow image source as an edge method).

Corner colors (top left, top right, bottom left, bottom right):
Specify colors to occupy the 4 corner pixels of the rectangle. This option will only have an effect for a particular corner if at least one adjacent edge uses that corner to generate the edge contents and the fill method uses that edge to generate the fill contents.

Gradients (top, bottom, left, right):
Specify gradients to occupy the edges of the rectangle. This option will only have an effect for a particular edge if the edge method chosen for that edge uses the gradient to generate the edge contents and the fill method chosen uses that specific edge to generate the selection fill.

Fill blend:
Choose between RGB, HSV (clockwise hue) or HSV counter-clockwise.

Edge methods:
Specify how to create the edge contents, either using a gradient between corner colors, using a specific gradient or using the existing image contents. This option will only have an effect for a particular edge if the fill method chosen uses that edge to generate the fill contents.

Fill method:
- If choosing Top to bottom, the left and right edges will be ignored.
- If choosing Left to right, the top and bottom edges will be ignored.
- If choosing a diagonal method, all edges will be used.

Edge repeat rule:
For each edge, allows specifying 0 to 9 repeats. "S" is for sawtooth repeat (color A to color B, repeat A to B, repeat A to B, etc.) T is for triangle repeat (color A to color B, repeat B to A, repeat A to B, etc.). The rule is positional. Specify count and S or T for top, then a space, then count and S or T for bottom, then a space, count and S or T for left, then a space, and finally count and S or T for right. The repeat rule for a particular edge will only have an effect if a gradient or adjacent corners are used to generate that edge and that edge is used by the fill method to create the fill.

Allow image source as an edge method in randomly-generated layers:
If you check this, generating a random layer can use the image source to create one or more edges of this layer. The downside of allowing this is that the layers produced using the image rule are harder or impossible to duplicate.

Known issues:
- May randomly fail, leaving a temporary selection active. If this occurs, Select All, then Select None to clear the selection.
- May not do a good job of handling gradients involving transparency/alpha.
- May not detect that the Current 2DG layer option has been chosen to use on a layer that is either not a 2DG layer or is a 2DG layer but has had its layer name changed. At the moment, anything not filled in by this procedure will be taken from the manually-set options.
- May not repeat evenly; there may be a sliver on the right or bottom which is particularly noticeable when sawtooth repeat is used.
- Includes unused options in the self-documenting layer name, which may lead to unnecessary effort by someone duplicating settings manually from reading the layer name.
- Is not sufficiently commented in the code.

Version history:

Version 1.2 Corrected gradient name logic so that the script no longer would fail from being used in a non-English installation of GIMP.

Version 1.0. Developed from Four-Corner Gradient and Gradient-to-Gradient scripts-fu. If you find 2DG has too many options, you might try one of these other scripts-fu instead.

Acknowledgements:

I gratefully acknowledge forum assistance from GIMP registry members Saul Goode and bootchk for helping me to understand particularly thorny (to me) aspects of TinyScheme. In addition, the 2DG code includes a number-to-hex conversion subroutine from Saul Goode which I also used as a model for a hex-to-number conversion subroutine. This assistance and code help me significantly in my quest to provide self-documenting layer names and using the self-documentation feature to allow retrieving settings from an existing, currently active, 2DG layer. I also appreciate forum assistance from Rob A, now known as ffaat.

Website Window Creator Script

dln385 — Fri, 27 Mar 2009 21:21:05 +0100

This script creates a new image with a window useful for web design.

To install this script, copy it to your scripts folder, then restart Gimp. If you don't know where your scripts folder is, then go to Edit > Preferences > Folders > Scripts.

To run this script, select File > Create > Website Window.

Feedback is appreciated, and I will consider any changes that you request.

G'MIC plug-in

dtschump — Tue, 13 Jan 2009 14:16:31 +0100

The G'MIC plug-in for GIMP defines a set of various filters, including artistic filters, image denoising and enhancement, 3D renderers, etc.. It is a quite large plug-in, integrating a lot of different effects to apply.

This plug-in is able to update his list of filter definitions from the Internet (so it improves itself over time), as well as allows any user to add its own custom filters in it.
It has been written by the author of the GREYCstoration algorithm (used for image denoising). It is actually intended to replace it in a near future.

Here is one screenshot of the plug-in in action, as well as a result of filter application :

SHAPEFS 1.2.0.0-20051020

alreaud — Mon, 07 Apr 2008 03:27:30 +0200

Shape from shading algorithms have been around for a while. Dr. Mark J. Carlotto describes a simplified version using basic trigonometry (Sculptor's Photoclinometry page in the Pacific-Sierra Research Image Shape from Shading section). In that section, Dr. Carlotto describes the Berthold Klaus Paul Horn algorithm for generating shape from shading, first described by Horn in 1989.

This plug-in generates a 3D image or movie from a greyscale source image based on the shading of the image, the sun azimuth, the camera angle (called phase angle), and the pixel size. Originally designed to be used with Mars Orbiter Camera (MOC) images, the user should be familiar with Mars Orbiter Camera ancillary parameters. The plug-in should work with any planetary data system or terrestrial image provided that the above parameters are available.

The results of this plug-in have been somewhat ground-truthed using an ISS image of the Giza pyramids. However, due to the inability to ascertain or enter albedo values for the surface in question, the results should be accepted with CAUTION.

The plug-in is very resource intensive, and requires maximal memory to function effectively on large (1000x1000) images. The author recommends a minimum of 512MB of system memory.
