PDF Viewer SDK Rendering Engine

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   In Delphi, the following results in the Viewer displaying black pages.The correct number of pages is displayed, so the PDF is loaded.

DPVActiveX1.DQPLSetDPLRFileName(ExtractFilePath(Application.exename)+ '\DebenuPDFRendererDLL1015.dll');

Rendererint := DPVActiveX1.DQPLSelectRenderer(3);

Selecting 1 or 2 as the renderer works, but the quality is poor.

I have verified that the DLL's and OCX are in the application's directory.

TIA for any hints.

John

	Hi John, ExtractFilePath should extract the path WITH the ending backslash. So you've two backslashes and the dll won't be found. Cheers and welcome here, Ingo Edited by Ingo - 22 Jul 14 at 12:05PM
	Cheers, Ingo

	Ingo, Thanks for the help. Unfortunately, I tried it without the additional backslash with the same results. BUT, it is even more embarrassing! I had inadvertently deleted the rendering DLL when I uninstalled the viewer trial and went to the licensed version. Its always the pennies that hold up the dollar!!! Thanks again. Your help pointed me in the right direction. All is working well. John
