Move, Scale, and Rotate using paths as reference

This is a collection of four scripts which help with aligning layers for HDR and mask workflow, as well as simply scaling, moving, or rotating layers.

Vector Path

This is a vector path generator script with a few modes and options. Visit Home Page for details and download.

Vector Path Plugin

Path Blend

A script that will blend a gradient between two paths, so long as each path has the same number of segments.

It registers under Filters->Render->Path Blend.

You have to select two paths (they must be different and have the same number of segments) and one gradient. The order of the paths corresponds to the direction of the gradient (From the first path To the second path.

path-arrow-heads

A plugin to add arrow heads to possibly curved path lines to relieve the frustration caused by all these straight-arrow scripts.

See http://gimp-path-tools.sourceforge.net/decorations.shtml

Path-Waves

Python plugin that draws a path of waves that follows another path used as reference. Paths can be stroked or mixed to produce fillable selections.


The python file is in this SourceForge project: http://gimp-path-tools.sourceforge.net/

Slinky

Slinky is a python plugin that generates a sine wave following an existing path. The sine wave can be spread between two paths to create a coil perspective around another object.

Slinky is available here: http://gimp-slinky.sourceforge.net/

Curve Bend Between Paths

This is a simplified front end to the curve bend script to help in straightening a distorted image. Create two paths with a maximum of 17 nodes each (drawn from left to right) tracing the existing image top and bottom curve, and it the script will calculate the curve bend parameters and run it to straighten the image.

After running the script, you can crop as desired, or perform further correction by shearing, or rotating the image by 90 degrees, drawing two new paths and running the script again

Image in sample was provided by lontarm at gimptalk.

Fractalize Path

This script will take the active path and fractalize it, using a random midpoint displacement algorithm, with the displacement proportionate to the length between nodes. Also the nodes don't move.

Parameters are:

Measure Active Path

Returns the length of the active path in pixels via gimp_message. A message will appear in the status bar, unless the Error Console is opne - in that case the message will be directed to the Console.

Filters->Measure->Active Path

Tested with 2.6.6 on Ubuntu 8.10 and Win XP.
