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.

Using transparency

When you draw anything new that overlaps with previously drawn objects, it simply paints over it so that you cannot see what’s behind it anymore. The PDF standard supports partially transparent colors that allow seeing what’s behind them.

A code is worth a thousand words, so let’s have an example. We will draw water, which is naturally transparent. And we’ll draw a duck, which is naturally in the water.

To have some waves in the water, we load the decorations.pathmorphing library that we used in the previous chapter:

\usetikzlibrary{decorations.pathmorphing}

TikZ has libraries and packages for everything useful and much silly stuff, so of course, there’s...
