PdfParser will throw an exception with error code ePdfError_NoPdfFile it the file is no valid PDF file. Though if you open the PDF using PdfMemDocument you will get this exception which you could catch.
A static method is not available, but could easily be added. I am not sure if
it is needed as you most likely will want to open the PDF with PdfMemDocument
anyways. So a static method would first parse the PDF file to see if it is
valid and than again in PdfMemDocument to read it. I think it is better to
parse only once in PdfMemDocument and throw an exception if the file is
invalid.
