Overview of this book

In this first-of-its-kind TikZ book, you’ll embark on a journey to discover the fascinating realm of TikZ—what it’s about, the philosophy behind it, and what sets it apart from other graphics libraries. From installation procedures to the intricacies of its syntax, this comprehensive guide will help you use TikZ to create flawless graphics to captivate your audience in theses, articles, or books. You’ll learn all the details starting with drawing nodes, edges, and arrows and arranging them with perfect alignment. As you explore advanced features, you’ll gain proficiency in using colors and transparency for filling and shading, and clipping image parts. You’ll learn to define TikZ styles and work with coordinate calculations and transformations. That’s not all! You’ll work with layers, overlays, absolute positioning, and adding special decorations and take it a step further using add-on packages for drawing diagrams, charts, and plots. By the end of this TikZ book, you’ll have mastered the finer details of image creation, enabling you to achieve visually stunning graphics with great precision.

Pre- and post-actions for using a path multiple times

We can have an arbitrarily complex path we want to use several times. TikZ provides an efficient way that spares us repeating coordinates.

Let’s look at the following path from Figure 7.4 from the previous chapter:

\draw[orange, line width=3mm]
  (90:2) -- (210:2) -- (330:2) -- cycle;

This draws an orange triangle:

Let’s say we want to draw this path several times with different colors and line widths to get a nice striped effect. The straightforward way to do this is by repeating the \draw command, like so:

\draw[red, line width=5mm]
  (90:2) -- (210:2) -- (330:2) -- cycle;
\draw[orange, line width=3mm]
  (90:2) -- (210:2) -- (330:2) -- cycle;
\draw[yellow, line width=1mm]
  (90:2) -- (210:2) -- (330:2) -- cycle;

Those three commands give us the following triangle in a mix of red, orange...
