Hi There,

I'm having a few issues with GetPageText(4), the one that returns each word and its quads. Several of the "words" still contain spaces in them, or they repeat themselves constantly. This issue doesn't happen if I extract a single line with GetPageText(3).

Here is some example output:

By Line:
"EOFGEO+Palatino-Roman",#000000,12.29,119.3814,705.3093,492.3365,705.3093,492.3365,717.7753,119.3814,717.7753,"nature, and thereby - or so he thought - freedom. Later, Bentham"

Is this a known issue? I'm tempted to do string processing and compare the two outputs but would prefer not to. Any guidance appreciated.]]> Tue, 30 May 2006 02:39:40 +0000 http://www.quickpdf.org/forum/extract-text_topic423_post1890.html#1890 <![CDATA[Extract text : &#034;...why did you write QP.Free...]]> http://www.quickpdf.org/forum/extract-text_topic423_post1889.html#1889 Author: Ingo

"...why did you write QP.Free two times?..."

Hi Quicker!

I've done it to prevent memory-problems.
Each 100 pages i'm starting new. So i can extract any document.

Best regards,
Ingo

Hi Ulrich,
why did you write QP.Free two times?

Hi Ingo,

thanks for your help but unfortunatly it doesn't work. It still cannot extract the word 'Test'. It only extracts the additional information:

"BAAAAA+TimesNewRomanPSMT",#000000,12.00,56.7000,776.6920,77.4240,776.6920,77.4240,784.7920,56.7000,784.7920,""

Also when I save the file and reload it bofore then it cannot extract anything (That's why I have set it in comments oin the code below).

here's the code I use (based on code of one of your former postings)

FName := 'c:\temp\test4.pdf';
QP := TiSEDQuickPDF.Create;
try
    QP.UnlockKey('');
    dafh := QP.DAOpenFile(FName, '');
    //QP.SaveToFile(FName);
    //dafh := QP.DAOpenFile(FName, '');
    x := QP.DAGetPageCount(dafh);
    STR := '';

    AssignFile(cf, FName + '_ex2.txt');
    Rewrite(cf);

    i1 := 1;
    pc := 0;

    for i := 1 to x do
    begin
      dapr := QP.DAFindPage(dafh, i);
      STR := QP.DAExtractPageText(dafh, dapr, 3);
      WriteLn(cf, Trim(STR));
      pc := pc + 1;
      if (pc = 100) then
      begin
        pc := 0;
        QP.DACloseFile(dafh);
        QP.Free;
        QP := TiSEDQuickPDF.Create;
        QP.UnlockKey('');
        dafh := QP.DAOpenFile(FName, '');
      end;
    end;
    QP.DACloseFile(dafh);
    CloseFile(cf);
finally
    QP.Free;
end;

Do you have any additional idea? As far as I have seen from looking on the code it seems that QuickPDF has problems this text, where the single letters are referenced objects (?)

I have emailed my test-PDF to you.

Ulrich]]> Mon, 29 May 2006 09:50:51 +0000 http://www.quickpdf.org/forum/extract-text_topic423_post1883.html#1883 <![CDATA[Extract text : Hi Quicker! I didn&#039;t get...]]> http://www.quickpdf.org/forum/extract-text_topic423_post1882.html#1882 Author: Ingo

Hi Quicker!

I didn't get any files from you.
Put them anywhere online and i'll see.
I think what i've written to Ulrich would help you, too.

Best regards,
Ingo

Hi Ulrich!

I've done the same with Word and the PDFCreator.
Extraction is possible:
First LoadFromFile
then SaveToFile //only to be sure that the file is readable with quickpdf
again LoadFromFile //the same saved file
then DAExtractPageText //with option 3!!!

Best regards,
Ingo
