In menu: Filters/Animation/Lightning Like Zeus (bg)...
Various versions and comments on Gimpchat.

This version:
Creates 5 lightning strike frames based on active path (you need to have an active path defined).
You don't need to install vector-to-line-stroke.py for proper operation (restored: 'gimp-edit-stroke-vectors' instead 'python-fu-vector-to-line-stroke' and 'colorize-hsl' instead of 'colorify').
Script use your selected active layer as background and remove it for you after it's done so that you're left with animation frames ready to export to gif/webp.
Note: Don't use black for 'Colorize HSL'.

Round Corners

 Round Corners - Ver. 0.4


Author: Markku Koppinen [aka: Ottia Tuota]

 On the author's website - it's here.

 More information and discussion at gimp-forum.net here.

 In menu: in the Paths tab, right-click a path and follow the links Tools > Modify path > Round corners.

Plugin to round path corners: Replace the corners by round arcs.
The path is assumed to consist of straight line segments.
Note: If you use a selection, out-of-canvas anchors are taken to be outside of the selection.
If you need to include out-of-canvas anchors in the selection, you have to enlarge the canvas temporarily first.

Example: With default input values the plugin did this:

 About the inputs:

Where to set the arc ends.

It offers two choices: the default is "Use fixed distance from vertices", and the other one I skip now entirely.
The value for 'distance' is input in the next field. The picture shows the meaning of "distance":


Distance of arc ends from vertices (pixels)

The list of the built-in shapes is:

    close to vertex
    through vertex
    one-parametric custom shape - set parameter value below

Parameter for custom shape

But in addition to these preset shapes, you may use any custom value: choose the option "one-parametric custom shape" and input some value for the parameter (default is 0.5).
For instance, you may want to try arcs flatter than circular but not quite straight; try then parameter=0.3, for example.
Any float number can be used, even negative (but not in fractional form unfortunately).

The built-in shapes are shown in pictures:

How to use the selection?

Which allows the user to make roundings only in some part of the path, keeping the rest untouched (just about).
About this I give one example. Suppose you have a path as on the left below. You want to round the corners but want to preserve the long arc.
Running the plugin as such would lose the arc (the plugin assumes that the path consists of straight edges and ignores all curvatures). You can protect the long arc as follows:
 (1) Create a new anchor; (2) make a selection; (3) call the plugin with "Round the corners only inside the selection."

BorderBox Ver.1.6

 MrQ BorderBox.

Author: MareroQ
Preview: Claude Lion [cli345],
Tabs: J.F. Garcia [arakne].


It creates frames with very different decorations.
The frame is created using paths (which can be used for additional decoration).
Uses additional interactive effects (invoking the plug-in with a preview of changing selected parameters).

The missing plugins (apply-canvas.exe, bump-map.exe, cubism.exe, engrave.exe, felimage-noise.exe, mosaic.exe, noise-generator.exe, noise-spread.exe, pixelize.exe, video.exe, voronoi.exe) from GIMP 2.8.22 work fine in GIMP 2.10 & Windows10_64bit and can be downloaded from this page or searched on GimpChat.

In menu: Filters → Decor → BorderBox...
