This topic briefly describes driver configuration for several of the tools provided. There's also additional information available in the source code headers for each class in the wwPDF.prg file that contains all of these classes.

• Adobe Distiller and wwDistiller
  
• GhostScript and wwGhostScript
  
• XFRX and wwXFRX
  
• AmyUni and wwAmyUni
  
• ActivePdf and wwActivePdf
  

Web Connection provides a group of wwPDF classes each of which implements one of the specific drivers or engines. The classes are functionally compatible and the main value of these classes is to provide easy, interchangeable pluggability.

To faciliate this process we recommend that you never hardcode the name of the class but rather use a #DEFINE. Web Connection (in wconnect.h) defines:

#DEFINE WWC_WWPDF               wwDistiller

You can override this to match your class in WCONNECT_OVERRIDE.H (or whereever you choose if it's not a Web Connection application). The override looks like this:

#UNDEFINE WWC_WWPDF  
#DEFINE WWC_WWPDF                  wwXFRX
*#DEFINE WWC_WWPDF               	wwDistiller
*#DEFINE WWC_WWPDF               	wwGhostScript
