Exploring the available decoration types
TikZ has decorations that change a path, also called morphing a path. This will be our next topic.
Other decorations replace a path with symbols; we will see them later in this section.
To summarize and compare, we will provide some figures containing several drawings or paths. The figure caption will include the options used for each path, always in order from top to bottom. You can find the code for each figure on GitHub and on TikZ.org on the page for this chapter.
Morphing paths
Morphing means modifying a path to become, for example, a zigzag or jagged line. We will distinguish between linear and curvy morphing. We have to load the corresponding library in the preamble by using \usetikzlibrary{decorations.pathmorphing}.
The decorations of this library have optional values, such as these:
amplitude: Determines how much the changed path goes above and below the original pathsegment length: The length of such a decoration...
