I need a list of all the possible error codes that can be returned from PDFToImageConverter.
Specifically, I am getting the value 2 returned when trying to convert a couple PDFs.
==========================
PDFToImageConverter does return following error codes,

//Return 0 is indicate the conversion success,
//Return -1 is indicate the parameters error,
//Return 1 is indicate the "File open error" or "Invalid PDF file",
//Return 2 is indicate the "Open Password-protected PDF file"
//Other values are indicate an unknown error,

==========================
The error is 2, but the PDF file is not password protected. Any ideas?
I tried passing both NULL, and empty string in the password parameters, but still got error 2.
==========================
