Hi Jean-Luc!

I've made similar experiences. I can only extract the text from my special document with GetPageText(4). Parameter 0 and 3 aren't working. Wonder why but i'm happy that it runs now with your help! Thanks a lot!

Cheers,
Ingo]]> Wed, 03 Sep 2008 01:38:16 +0000 http://www.quickpdf.org/forum/problem-with-textextraction-from-ocrpdf_topic931_post4446.html#4446 <![CDATA[Problem with textextraction from ocr-pdf : Hi again, I&#039;ve traced the...]]> http://www.quickpdf.org/forum/problem-with-textextraction-from-ocrpdf_topic931_post4445.html#4445 Author: DELBEKE

Hi again,
I've traced the program to understand the différence.
 
The text contained in your files is Unicoded, The method for extract the text with parameter 0/1 ( the parameter 0 and 1 are strictkly identical) do'nt use the rendering engine and ca'nt extract the Ansi string. This shoud be an improvement.

Hi Ingo
 
I've tested with GetPageText(Parameter)
With Parameter 0 and 1, no text extraction. Others works correctly.
 
Strange

Hi Jean-Luc!

This is already a help - I'll try the "normal" extract function ;-)

Cheers,

Hi Ingo
I have not try with the direct access functions. Today it is to late for me to have a try. And tomorrow , i will not be able to test. So i'll see that later, but i' ll dot it.

Hi Jean-Luc!
 
How are you using the extract function?
My code still doesn't work. If you want to look:
   QP := TiSEDQuickPDF.Create;
   try
       QP.UnlockKey('mycode');
       dafh := QP.DAOpenFile(fneu,'');
       x    := QP.DAGetPageCount(dafh);
       STR  := '';
       ProgressBar1.Min := 0;
       ProgressBar1.Max := x;
       verztxt := fneu + '.txt';
       AssignFile(cf,verztxt);
       Rewrite(cf);
       for i := 1 to x Do
       begin
          ProgressBar1.Position := i;
          ProgressBar1.Repaint;
          dapr := QP.DAFindPage(dafh,i);
          QP.CombineLayers;
          STR  := QP.DAExtractPageText(dafh,dapr,0);      
          WriteLn(cf, '   ');
          WriteLn(cf, ' page ' + IntToStr(i) + ' from ' + IntToStr(x) + ' ');
          WriteLn(cf, '   ');
          WriteLn(cf,Trim(STR));
       end;
       CloseFile(cf);
    finally
       QP.DACloseFile(dafh);
       QP.Free;
       ProgressBar1.Position := 0;
       Screen.Cursor := Save_Cursor;  { Always restore to normal }
    end;
 
Thanks a lot!
 
Cheers,
Ingo

Hi Jean-Luc!
 
I'm in England actually - so this late answer.
I'll try it with combine layers. Thanks a lot.
If you have any enhancements for the library please send it first to me. I'll always implement it and then i send the whole package to Michel and he upload it for new testing for the members.
 
Cheers and best regards,
Ingo

Hi Ingo.
No problem for me, it works perfectly.
In your document, the text is on an separate layer. Try to use the CombineLayers function before then GetPageText function
I've made some enhancements for this function, perhaps, you missed this post http://www.quickpdf.org/forum/forum_posts.asp?TID=923
In the meanwhile, i've made more enhancements for the annotations functions and send them to Michel, but it seem to be on hollidays.
For now, i am working on a digital signing funtion, but i have somes difficulties whith Delphi (i've just begin with delphi on july).
