The ImageGear API provides content editing functionality for creating, accessing, and editing PDF page content objects. With this API you can work with a page's content as a list of objects, such as images, text, forms. You can retain, modify, and save their data and properties.

Document font support includes:

• Listing the fonts available in the host system and finding a system font that matches a PDF font
• Creating a font from the system font and encoding as well as from the specified attributes
• Changing a font's information
• Editing and embedding a font in the document
• Both single and multiple byte fonts are supported

For a demonstration of how to add a text element to the content of a PDF, see our PDFContentAddText sample on github. This example demonstrates creating a font, using the content in a PDF, and creating a text element.
