Hello Andrew, Ingo,

thank you for help!

Now it works.
I think my fault was not to use the function "DAFindPage".

Thank's again!

You need to be using the following code.  As Ingo mentions the DA functions should only be used with other DA functions.  

  fh := QP.DAOpenFile(fn, '');
  ph := QP.DAFindPage(fh, 1);
  width := QP.DAGetPageWidth(fh, ph);

You might find it easier to use the non-DA functions which also support much more functionality.

  rey := QP.LoadFromFile(fn, '');
  if (ret = 1) then
  begin
    QP.SelectPage(1);
    QP.SetMeasurementUnits(2);
    pageWidth := QP.PageWidth();
  end;

Also by default QPL always has a single 1 page document loaded in memory and this is why QP.PageWidth is returning 8.5.

You might find it useful to read parts of the Developer Guide PDF that comes with QPL.

Andrew.

Hi Gini!

Please keep in mind never mix da- and non-da-functions.
A DALoad... isn't a real load so the non-da-function PageWidt won't get a correct result.

Cheers and welcome here,
Ingo

Hello all!

I've problems to get the page width and height of different existing documents
of different page sizes (as Adobe Reader confirms).


Using PageWidth (with measure unit "Inch") I allways get 8.5
Using DAGetPageWidth I allways get 0.0

maybe there is something wrong in my code (Delphi XE2):


handle := fPDFLib.DAOpenFileReadOnly( fn, '' );
fPDFLib.SetMeasurementUnits( 2 );
if ( fPDFLib.SelectPage( 1 ) = 1 ) then
   docWidth := fPDFLib.PageWidth;

OR
docWidth := fPDFLib.DAGetPageWidth( handle, 1 );



Have anyone an idea what is going wrong?

Thank's!
Cheers, Ginidat
