Make gradient from panoramics photographs

Giuseppe — Tue, 07 Jul 2009 12:33:13 +0200

With this script is easy to create gradients that they simulate a sunset or a natural landscape. You take a photo panoramic, it selects a thin vertical strip and it rotates it in counter-clockwise direction. You read the maximum width of the image and insert it (width / 2) like number of segments in the dialog box of the plugin.

Examples of images created with the plugin

Sample Gradient from Image

ffaat — Fri, 01 May 2009 00:51:13 +0200

This script compliments my "Sample Gradient Along a Path" script and was originally developed to generate the gradients bundled here. This script simply scales the image to be 1 px high and samples across it, so it only works correctly with horizontal gratent images.

You can however create some interesting gradients with other images. For example, an image that is 1/2 black and 1/2 white diagonally will creat a gratent that blends linearly from black to white!

Please note the script registers under the Gradient Menu (from the gradient dialog).

This version has been updated from the original to support alpha in the gradient as well.

Four-corner gradient

Version 2.4

This Script-Fu creates a completely new image having an RGB and/or HSV gradient in two directions - both horizontally and vertically - based on the colors you specify for the four corners. The layer name includes the parameters to support reproducibility.

Superceded as of 4/26/09 by 2-Dimensional Gradient.

Version 2.4: layer name color parameters shown in hex to facilitate copying into color widget. Thanks to Saul Goode for code that lets me enable this feature.
Version 2.2: layer name includes all parameters except width and height, to facilitate reproducibility.
Version 2.0: defaults to most efficient execution sequence; adds cycling.

Tip: Because the logic of this script involves processing one column or row at a time, you may want to test on a smaller image until you find a desirable gradient, then create a larger image using the same settings.

If you choose RGB for both directions or HSV for both directions, the sequence does not matter, so you might as well let the program choose the most efficient direction.

If you mix RGB in one direction with HSV in the other, the processing sequence - RGB first or HSV first - will affect the appearance of your resulting image. If you've mixed them, you may want to try forcing a particular sequence for applying the gradients.

Once you've saved this Script-Fu in your Script-Fu directory, you will find it filed under Filters > Render > Gradients > 4-corner Gradient 2.0...

Known issue: The script may occasionally quit with an error when setting the foreground color. Re-running the script with the same parameters seems to fix the problem.

Known issue: As of GIMP 2.6.6, the programming interface provided by GIMP does not support scripting control over HSV gradient directionality (clockwise vs. counter-clockwise hue). Therefore, the choice of the directionality of such gradients may appear arbitrary - and may even be arbitrary. Occasionally, you may find that certain uses of the HSV settings in the Four-corner gradient Script-Fu may result in two adjacent rows or columns of pixels following the opposite hue directionality. There is nothing to be done about this at this time except, if you find the resulting image not useful, to try other settings.

The image in my profile was created from Four-corner gradient version 2.0 Script-Fu with settings: 85 85 ff0000 00ff12 00bfff ffaf14 HSV No cycling RGB No cycling Left/right edges first.

60's Text Effect Script (Rev. 2.2)

PhotoMaster — Tue, 24 Mar 2009 21:12:10 +0100

This script will create psychedelic 1960's text. I created this script from my tutorial of the same name. I didn't merge the layers in the script, as I did in the tutorial, because you can change the blend modes of the different layers for different appearance.

Rev. 2.0 - added compatability for Gimp 2.4.x

Rev. 2.1 and 2.2 - Added gradient controls.

Gradient-to-gradient Gradient

Version 1.0.2

This script-fu creates a completely new image having an RGB and/or HSV gradient vertically between any two GIMP gradient patterns.

Note that this script-fu has a repeating loop, so the wider you make this image, the longer the script will take to run.

Find in Filters > Render > Gradients > Gradient to gradient...
