PDFs are embedded using a standard anchor element tag that links an image to the PDF file. When the image is tapped, it opens the PDF in a new window where the reader can pan and zoom-in.
Note: When including PDFs, keep in mind the maximum overall book size of 2GB. Larger PDFs may also cause poor performance on some devices.
The tag references the PDF file and the image is nested in the anchor element.
