Font handling

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

   While handling PDF documents with the library I often add texts with different fonts. I saw that using AddTrueTypeFont returns me an incremental ID value even if the document was closed and changed or even if I add the same font several time in the same document. Does this mean that all the font I added are still in memory even if the document was closed? Is there any function I must call to free the library resources after one document is closed?
Thank you,
Giorgio

	Hi Giorgio, if the document you've worked on was closed you should call an ending Library.Free to wipe out the memory. Here you can read about the functionality: http://www.debenu.com/docs/pdf_library_reference/AddTrueTypeFont.php Here's the demo-link to test/try the functions with the library: http://www.quickpdflibrary.com/blog/2009/10/a-customizable-demo-for-quick-pdf-library/ Cheers and welcome here, Ingo
	Cheers, Ingo

	Hi Ingo and thank you for your reply, but: 1- I am using the Activex version, do you mean I must use CreateObject method for each document I open and destroy the class instance after having processed it? 2 - My program is running on a server and processin continuously PDF files, loading and freeing the library for each file found should drive to an unnecessary overload for the system... Have I misunderstood something? Thank you Giorgio
