Q:

PDFTron SDK provides option to add bookmarks in PDF document which is really good. Is there any option to change font size of these bookmarks? I can see an option in PDF reader tool but I want to make it default small size.

The PDFs are opened by our customers using the web browser, mostly IE9 and Chrome. Also customers open the PDF using Acrobat Reader.

A:

Although the PDF format allows one to specify the color of Bookmark text, as well as whether the text is bold and/or italicized, it does not allow one to specify font size.

For details, please see PDF ISO Specification (32000-1:2008), 12.3.3 "Document Outline", tables 153 and 154.
