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.

Understanding decorations

The TikZ syntax can be pretty verbose. That’s particularly the case with decorations. Even adding arrow tips along a path can be wordy. As this is an excellent example of what TikZ decorations can do for us, let’s try this.

Let’s create an arrow from (0,0) to (2,0). We can do this with the following code:

\draw[-stealth] (0,0) -- (2,0);

We have an arrow tip at the end of the path, but we also want to have arrow tips along the way. First, we must load the decorations.markings library:

\usetikzlibrary{decorations.markings}

Then, we must choose the decorate option as postaction, with a decoration type of markings, in steps of 0.2 between positions 0.2 and 1:

\draw[-stealth, postaction = decorate,
  decoration = {markings,
  mark = between positions 0.2 and 1 step 0.2
  with {\arrow{stealth}}}]
    (0,0) -- (2,0);

The syntax will be explained in detail later in this chapter...
