No problem Marco, it was fun to refresh my C++ knowledge. Please don't forget that
the major work on this library wasn't done by me but by the original authors of Xpdf.
For all the others here is the link: http://rapidshare.com/files/172190796/pdf2text.zip

milan1612's pdf2text.zip contains the following code example:

Code: Select all

Prototype.l ExtractPDFTextProto(PdfFile.s, OutputFile.s)
If OpenLibrary(0, "pdf2text.dll")
  Global ExtractPDFText.ExtractPDFTextProto = GetFunction(0, "ExtractPdfText")
Else
  End
EndIf

If Not ExtractPDFText("c:\LTB2658_1.pdf", "c:\LTB2658_1.txt")
  MessageRequester("Error", "Could not extract pdf text!")
EndIf

Although this code example works it contains a nasty bug which
you will experience if you put the ExtractPdfText function into a
procedure: you will see a crash in the procedure because you have
to use PrototypeC instead of Prototype...

For an explanation take a look into the PureBasic blog:

freak wrote:Here we get to the reason why it works outside of a procedure and not inside. A call to a procedure stores the address where execution continues after the procedure on the stack as well. If a function call inside the procedure leaves the stack in a mess, then the ProcedureReturn cannot find the address to continue and uses a wrong value instead which leads to a crash. Outside of a procedure, nobody will notice the stack mess, as the stack is only used for function calls.
