Modern SVG

Chapter 3. Beyond Straight Lines

From SVG Text Layout

Baselines ensure that glyphs are positioned to create a pleasing line of text. However, we’ve already said that, in graphical layout, you don’t always want text to display in perfectly straight lines. Sometimes it’s fun to make text move out of those boring lines and into more complex curves—circles, spirals, around the edges of various objects, and so forth.

This chapter introduces the <textPath> element, which allows you to use SVG path geometry to describe complex text layouts.

Creating Curved Text

We’ve shown (in Chapter 5 in SVG Text Layout) how you can position and rotate individual characters. For some simple designs, that’s enough. Example 3-1 spaces the letters of the word “Sunrise” in a semicircle, each letter positioned every 30° and rotated to match, as shown in Figure 3-1.
