When converting PDF documents to SVG, jPDFWeb will try and preserve fonts using the following logic:
Any embedded font present in the PDF document will be extracted and embedded in the ouput SVG files as WAF fonts.
Any of the 14 standard PDF fonts
For any of the 14 standard fonts referred by name, the corresponding standard font (Qoppa’s own font) will be embedded in the SVG.
Other referenced fonts
For any other font that is referred by name but that is not embedded in the PDF document, jPDFWeb will try and find a matching font among the operating system fonts of the server running the library, otherwise it will default to a standard font.
