Hi!

You can try something similar to the following code:

   try
      QP.UnlockKey('...');
      QP.LoadFromFile(ipfliste[di]); //fneu);
      pmax := QP.PageCount;
      Form1.Label1.Caption := title;
      QP.CombineLayers;
      test_stream := TMemoryStream.Create;
      QP.RenderPageToStream(zoom,page,1,test_stream,1,0);
      Form1.Show;
   finally
      QP.Free; 
   end;

   Form1.Repaint;

   try
      test_stream.Seek(0,0);
      jpg := TJPEGImage.Create;
      jpg.LoadFromStream (test_stream);
      Form1.Image1.Picture.Assign(jpg);
      Form1.Caption := title;
      Form1.Label1.Caption := 'Document 1 of ' + IntToStr(rcount);
      Form1.Label3.Caption := 'Page 1 of ' + IntToStr(pmax);

   finally
      Form1.Show;
      test_stream.Free;
      jpg.Free;
      result := 0;
   end;

I don't use ActiveX. If you wanna use it
you should change from RenderPageToStream
to RenderPageToFile.

As file you can choose jpeg or bmp for example
and this image you can display in your image component.

Here is the online reference:

And please tell me how to render into stream when I used ActiveX. Is it possible and how?
In manual is information for RenderPageToStream: This function is only available in the Delphi edition.

Hi!

"SetViewerPreferences" has nothing to do with YOUR pdf-viewer.
SetViewerPreferences on a loaded document before SaveToFile will manipulate a pdf-reader while displaying your document.
With SetViewerPreferences for example it's possible to determine that your document shall be opened on the third page and that the reader-menu shall be hidden.
If you've done the SaveToFile and opened the document with a pdf-reader the starting page will be the third one and the menu will be hidden.

Cheers, Ingo

O.K. I can render to Image or PaintBox now, but tell me how to use SetViewerPreferences?
I really dont understand how work QuickPDF library. I thought that I can use it as visual component for preview PDF files with Toolbars for zoom, moving, etc. ?

Thank you

Hi hloch!

Why you didn't use the search-function above (with the advanced option)?
Here are two helpful links for you:
http://www.quickpdf.org/forum/a-pdf-viewer-built-using-powerbasic-and-quick-pdf_topic1050.html
http://www.quickpdf.org/forum/pdf-view_topic329.html

Normally it goes this way:
Get each page - convert pagecontent to stream - convert stream to jpeg - load the jpeg into an imagecomponent - ...

Cheers and welcome here,
Ingo
