The Text Along Path tool allows you to draw a Text path along another existing path. For instance, you could create a Line Segment, warp it using the Move Bezier Point tool and then draw the text path along this curve. Here’s an example.
The are several construction options available when creating a Text Along Path. You can retain or delete the path along which you draw the new Text path. By default, the text is drawn starting at the beginning of the path, but you can change the offset so that it’s drawn further along the path (the X Offset) or even above or below the path (the Y Offset). You can also draw the text using the current Font Size of the currently selected paint set or you can dynamically size it.
