script-fu

Implements a new version of smart sharpening (redux) combined with separate sharpen to give better results. Thanks to Michael Kolodny for working on this.

Tutorial: http://www.gimpguru.org/Tutorials/SmartSharpening2/

Updated to work with Guimp 2.8.

script-fu-simple-contrast-mask adds a contrast mask layer above the current active layer. A contrast mask brightens the dark parts of an image and darkens the bright parts. This serves to enhance details.

The script is called "simple" because it does not ask any questions. It assumes defaults for all parameters. Specifically, the radius for the Gaussian blur is set to one percent of the shortest dimension of the image (width or height). The user can adjust the blending level after creation by adjusting the opacity in the layers dialog.

This script is used to draw user defined or library parametric curves.
A simple java like math language is used to define curves or families of curves in GIMP layers. These can be exported to animated GIF's, SVG path, or included in GIMP images.

This script-fu makes a sky with millions sparkling stars in a new layer. The layer's dimensions, the star's spikes' length and the flare intensity can be changed. The script is based on this tutorial.
This script is useful for create Space Art images, because the stars are convincing.
Good creating !

A simple script to generate a wood grain pattern. You can control for the dimensions of the resultant pattern. Results are generated in a new layer in the active image.

Version two (sf-will-wood-gradient.scm) allows you to control banding frequency, and specify your own colours

This script set's guide at the "Rule of Thirds" lines.

This little bit of Script-Fu converts all images of a specified extension in a single folder to greyscale .gbr files. script-fu popup prompts you for the folder containing the images, and which extension to filter on.

Brushes are created in the same folder as the images, using the original filenames (but with .gbr as the extension instead of frex. .jpg).

Tested in Windows XP with GIMP 2.6 - not tested in other environments or versions, but as this script is very bare bones, it should work on any GIMP version from at least 2.2 up (not sure about earlier).

A simple script to make the edges of a selection or layer glow with the selected colour. The script will act on the active selection first, and if it cannot find that, the alpha channel of the current layer. All changes are made to a separate layer so you can duplicate, mask and move them around to your heart's content.

Resize-match-dpi is a GIMP Script-Fu script to resize or scale an image along with scaling the DPI. If we scan a 4.75″ x 4.70″ image at 300 DPI with a pixel resolution of 1425 x 1409 and we want to scale it down to 1280×1266, most programs will rescale the image but not touch the DPI. This means when the image is viewed or printed it will appear too small (4.27″ x 4.22″). This script scales the DPI to match the new pixel resolution so it will still appear as 4.75″ x 4.70″. Comments are greatly appreciated.

Version 0.9.6

Just getting this up, so the description will be short for now. Double HSV Film Grain was originally a work-around that simulates Photoshop's film grain filter. It has become more than that, though. Simple to use, it has a few features that go beyond simple noise filters. There is the option to either compress the layers down to the original, or keep the three separate working layers to be manipulated individually. There is also an option to limit the working layers to just two noise layers.

Still testing it for bugs, so any input would be appreciated.
