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.

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;

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
