14.15.1. Overview

Figure 17.352. An example of a rendered maze.

Filter “Maze” applied

This filter generates a random black and white maze pattern. The result completely overwrites the previous contents of the active layer. A typical example is shown below. Can you find the route from the center to the edge?

14.15.2. Activating the filter

This filter is found in the image window menu under Filters → Render → Pattern → Maze….

14.15.3. Options

Figure 17.353. “Maze” filter options

Presets, Preview, Split view, Use selection as input

	Note
	These options are described in Section 2, “Common Features”.

Width, Height

These sliders control how many pathways the maze should have. The lower the values for width and height, the more paths you will get. The same happens if you increase the number of pieces in the Width and Height Pieces fields. The result won't really look like a maze unless the width and height are equal.

Algorithm type

You can choose between these two algorithms for maze: Depth first and Prim's algorithm. Only a computer scientist can tell the difference between them.

Tileable

If you want to use it in a pattern, you can make the maze tileable by checking this check-button.

Seed

You can specify a seed for the random number generator, or ask the program to generate one for you. Unless you need to later reproduce exactly the same maze, you might as well have the program do it.

Foreground color, Background color

You can choose colors for the maze and its background. Defaults are Toolbox colors.

Clipping

The result of this filter can be larger than the original image. With the default Adjust option, the layer will be automatically resized as necessary when the filter is applied. With the Clip option the result will be clipped to the layer boundary.
