Hi,

SetFillColor and DrawBox API functions does not work, when PDF file is accessed using QP.DAOpen("xxx.pdf") API function , but they work, if file is loaded using  QP.LoadFromFile("aaa.pdf");

Please let me know, if you have any solution for this, I want to make SetFillColor, DrawBox functions to work,when file is accessed using DAOpen().

I am using:  DEBENU PDF Library version: 12.11 ,win32 API and C/C++.

Regards
Lakkan.

Hi Lakkan,

you should NEVER mix DA- and non-DA-functions.
This won't work...
Please read about DaOpenFile:

Hi Ingo,

Thanks for your information.

I require to implement FillColor and DrawBox functions, after opening the file with DAOpen API.

Are there any alternate DA functions, which fills the color  and draw the box in DAOpen Mode.

Please let me know, if you have any information on that.

Regards
Lakkan

Hi Lakkan,

there aren't alternate DA functions for this.
In your case you should avoid DAOpen.
Use the similar LoadFromFile.
The DA-functions were made long ago - the library couldn't handle large files proper in the past...
Today you shouldn't need the DA-functions anymore.
Cheers,
Ingo

Hi
I've prepared code below:

var
  QP: TDebenuPDFLibrary;
begin
  dlgSave.FileName := 'Rotated.pdf';
  if dlgSave.Execute then
  begin
    QP := TDebenuPDFLibrary.Create;
    try
      if QP.UnlockKey(edtLicenseKey.Text) = 1 then
      begin
        QP.SetPageSize('A4');
        QP.SetOrigin(1);
        QP.SetMeasurementUnits(1);

        QP.SetFillColor(230, 230, 230);

        QP.DrawBox(10, 10, 10, 10, 1);
        QP.CompressContent;
        QP.SaveToFile(dlgSave.FileName);
      end else
        MessageDlg('The license key is invalid or has expired.', mtError, [mbOK], 0);
    finally
      QP.Free;
    end;
  end;
end;

It seems, calling the command SetFillColor with those parameters doesn't cause drawing gray square like it should be done. Is there something am I doing wrong? I am very beginner with QuickPDF Library.

Hi MyNameIsMyName,

did you read all about SetFillColor?
No... you didn't ;-)
http://www.debenu.com/docs/pdf_library_reference/SetFillColor.php
The values representing the colours has a range from 0 up to 1 ( SetFillColor(1,1,1) means black ).

Cheers and welcome here,
Ingo
Cheers,
Ingo
