Comments

The user calls this function to override the default path of the PDF initialization directories. This allows the user to choose which PDF runtime library his or her application loads at runtime.

The default PDF initialization directories path is stored in the system registry key: "HKEY_LOCAL_MACHINE\SOFTWARE\LEAD Technologies, Inc.\Pdf\GS_LIB"

If you call this function with an empty string (length = 0), then the engine will look for the PDF initialization files in the default PDF initialization directories path (specified by the registry key).

The new path must both exist prior to calling the function and contain the Lib, Font, and Resource directories for the PDF Filter. If either of the above is not true, the engine fails and returns an error when the user attempts to load a PDF file.
