RSS Lightsaber (LSE) v0.9

spoilt_exile — Tue, 17 Nov 2009 23:26:13 +0100

RSS Lightsaber (or LSE) is a simple script for creating lightsaber effect in picture. The script base on my own algorithm.
Features:

Fast script's execution.
Independent setting for blur size of the lightsaber's core and glow around saber.
Some features to provide correct effects on extra large photos (above 20 Mp).

The basic documentation is inside archive. Enjoy!
Next release (v1.0 with new documentation and lessons) in December 2009.

Blur & Shadow

Guillaume57 — Tue, 17 Nov 2009 13:32:46 +0100

Creates a picture which is a duplication of the current picture blured as background,
and the current picture itself reduce with a border and shadow around it as foreground

Example:

Quadrupole

theilr — Thu, 12 Nov 2009 05:26:01 +0100

Takes an image, makes four 1/4 scale copies, and reflects them about vertical and horizontal axes to achieve a four-fold symmetry.

Note: As well as being atrociously inefficient (eg, by scaling the same image four times, instead of making copies after the first scaling), this code does substantially less than the "Small Tiles" dialog (which comes standard in Gimp in /Filters/Map)

Cheap HDR

theilr — Thu, 12 Nov 2009 05:05:32 +0100

Provides a kind of poor-man's HDR (high dynamic range). It doesn't actually increase the dynamic range; in fact, it decreases it, overall, but in a way that maintains local contrast. But this gives you some headroom to increase the contrast of the image overall, thus enhancing the local contrast.

Jagged Border

theilr — Thu, 12 Nov 2009 04:48:18 +0100

Creates a white (or black) border around an image that merges in with the image so that on a larger white (or black) background, the image appears to have a ragged border. This is similar to the Gimp's Fuzzy Border, but it adapts its jaggedness to the image. (Also unlike Fuzzy Border, it is deterministic, it does not depend on random number seeds.)

Some examples of what I mean by a jagged border that "adapts" to the image, which also illustrate the difference between a white and black border (it's not just the color), are shown in this triplet of images:

Draw arrow

B-Ranger — Wed, 11 Nov 2009 16:47:35 +0100

Update [11/15/2009] : Added fixed brush width and double headed error, removed bug 1) one-point-paths, 2) horizontal paths
Update [11/16/2009] : Fixed image type restriction string
Update [11/19/2009] : Added feature for absolute wing length, fixed handling gray-scale images

This plugin enables GIMP to draw an arbitrary arrow into an image or a new layer. The plugin has reasonable default values for every paramtere but is freely adjustable to ones needs. Parameters are:

wing length and line width freely adjustable (relative & absolute)
angle between arrow tail and wing
optional draw arrow in new layer
optional filled or not filled head
optional notch in arrow head
optional delete used path
optional draw double headed arrow

Usage:
Create a path (usually <B>) with the head of the arrow (first anchor point) and the end of the tail (second anchor point). Then call the script which adds itself to the "Tools" menu (I use <AltGr+P> as the shortcut as "Pfeil" is the german word for arrow).

ToDo:

Write documentation (any one can help me with that and knows how to?)
Open for suggestions
Enable a more angularly arrow

Calendar maker

saulgoode — Mon, 09 Nov 2009 14:10:26 +0100

The script I've written adds two layers to an image which overlay the active layer with dates and a grid of lines producing a calendar for the specified month. It is not so much intended to create a complete calendar, but to be used as a tool in creating calendars. The command appears in the menus as "Filters->Render->Calendar..."

The options presented in the dialog are:
* Month - the month to be used
* Year - the year to be used
* Sunday first - if checked then Sunday is the first day of the week, otherwise Monday
* Font - the font to be used
* Fontsize - The size of the numbers used for the dates. 100% will use the largest possible
* Right justify - If checked then the date will be right-justified in a field two characters wide
* Border width - determines how thick the lines of the grid will be (can be "0" for no grid)
* Border color - color used for grid (note: FG color is used for the text)
* Date position - the alignment of the date number within its box

The month and year are not generated on the image; they should be added to the image manually if desired. For reference, the month and year appear in the layer names of the newly created layers.

EDIT: When called from the PDB, the script will return a list containing the "dates" layerID and the "grid" layerID.

EDIT2: I have updated the script and added a "Layout" option which offers the following treatments of the dates:

* Allow 6 weeks (resizing text for optimal fit)
* Force 6 weeks (use six rows of weeks in all cases, even for a 4-week February)
* Wrap week 6 to week 1 (the approach proposed by wbool)
* Wrap week 6 to week 5 (and if needed compressing two days into a single cell)

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...

Spaced V-Guides

jboulais — Fri, 16 Oct 2009 15:55:12 +0200

This script creates a series of V-Guides in the image at the user defined spacing. The user also specifies if the guides should start from the left, center, or right side of the image.
