Examples of com.lowagie.text.exceptions.UnsupportedPdfException

com.lowagie.text.exceptions.UnsupportedPdfException
Typed exception used when opening an existing PDF document. Gets thrown when the document isn't a valid PDF document according to iText, but it's different from the InvalidPdfException in the sense that it may be an iText limitation (most of the times it isn't but you might have bumped into something that has been added to the PDF specs, but that isn't supported in iText yet). @since 2.1.5
