-----------------------------
Hi [~tilman], how do I make sure the file is transferred in binary mode? Also,
how do I make sure the filtering is off, and perform MD5 checksum? Sorry for
these enquires as I am new to the library. The following are my current codes:
PDDocument {color:#6a3e3e}document{color} = PDDocument._load_(new
File({color:#6a3e3e}filename){color});
PDFTextStripper {color:#6a3e3e}tStripper{color} = *{color:#7f0055}new{color}*
PDFTextStripper();
{color:#6a3e3e}tStripper{color}.setSortByPosition(*{color:#7f0055}true{color}*);
String {color:#6a3e3e}pdfFileInText{color} =
{color:#6a3e3e}tStripper{color}.getText({color:#6a3e3e}document{color});
//error seems to occur at this line
Thanks a lot for your help.
