Hello!

I've problems with DAExtractPageText on few pdf files.
The first problem you can find in this file here:
http://www.is-soft.de/brochure.pdf
Here i can't extract the german umlauts like � or � for example.
From a link like http://www... i get only httpwww... What's that?
The pdf file was made with a very old pdf tool and pdf version 1.1 ;-)
The second problem are files like this one:
http://www.is-soft.de/invoice.pdf
There is text but no embedded fonts... I can't extract anything.
If anybody here have few advices for me in this case i would be very happy!
Thanks a lot in advance!

Below there's my code...

    QP := TiSEDQuickPDF.Create;
    try
       QP.UnlockKey('*****************************');
       dafh := QP.DAOpenFile(FName,'');
       x    := QP.DAGetPageCount(dafh);
       STR := '';

       lstr := 0;
       strges := '';
       i1 := 1;

       for i := 1 to x Do
       begin
          dapr := QP.DAFindPage(dafh,i);
          STR := QP.DAExtractPageText(dafh,dapr,0);
          strges := strges + STR + #10#13 + #10#13;
          lstr := lstr + Length(Trim(STR));
       end;
       QP.DACloseFile(dafh);
    finally
       QP.Free;
    end;

I've been using the "GetPageText(3)" function and it returns the backslashes properly (/). However, I have found that I can only read text if it's a standard font (Arial/ Courier or Times-Roman). Embedded fonts return nothing, but I only tested subsetted fonts.

I have not tested umlauts, so I can't comment on those.

Hi Ingo,

I have the same problem... also with a INVOICE

iSED LastErrorCode report "401 Could not open input file"

I have try to included a font (Courier or Arial), but not work,
If i open the INVOICE with Acrobat and save it, i can extract text with iSED or Pdftext

have you find something new or find a fix to PdfText?

Regard

Hi!

I only know that it ahve something to do with using the pdftools FreePDF and/or PDFCreator (they're working with GhostScript). Documents created with acrobat or something else in this price section don't have this problem.
