EVO HTML to PDF Converter allows you to add text with various fonts to a PDF document. A text element is represented in API by a EvoPdfTextElement object.
You can add text elements using the fonts installed in system, fonts from local file system and standard PDF fonts. You can also add vertical text and text stamps to PDF, render the text in a given box or flow the text on multiple pages.
