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:

Here's the demo-link to test/try the functions with the library:

Cheers and welcome here,

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

ad. 1

do you also close entire process ?

ad .2

my programs run and process 2000 PDF, after that user close programs,

Each file is processed by separate ObjCreate, but I do not have such problem,

Which one DevEnv you are using ?
