This script-fu (created mainly from the script "add-bevel.scm" which is installed by default) adds to an existing layer, a layer composed of squares or rectangles (size of your choice) in shades of gray but with bevels. The goal is to facilitate the creation of pavements with a little "volume". arfff. Difficult to explain -_-'

This script-fu rotates an image -/+ 26.57 degrees to help to make an isometric roof. There are some little options to resize, to cut the semi-transparent pixels, to merge down.
I don't know if this script will be very useful. It is for me, so I am sharing.

This is a very simple script for method of image processing othen used by myself - splitting picture into a two assembled layers: colors and grain. This gives us a very lot of capabilities of changing picture without making a hard artefacts inside it.
Suppose the current layer has a tile-based image (e.g. the tileset for a game). This script will transpose all tiles, so that the tile at the position (1,0) will end at (0,1).
Very useful if you have your sprite sheet as a tall strip of frames (one on top of the other), but you need it as a horizontal strip (with frames side-by-side, as required by Game Maker). With this plugin, you can transpose the frames to convert from one format to another.
This script will rotate an existing image about the X, Y and Z axes. It will also include a magnification factor so you can scale your image while rotating.
The inputs are the angles to rotate the image around the X, Y, and Z axes. Some values (usually high X and Y values) will result in a very distorted picture, regardless of what other inputs you have. If you get one of those, just undo and try again. That's just the way math works, folks!
sprite-tape converts multiple "frames" (think animation frames) one per layer to an image of an array of "frames" in a single layer with a specified gutter between frames. sprite_tape-0.4 differs from 0.3 in the way that the gutter between frames is created.
