PDF Editor Layer
PDF Editor Layer provides the most versatile and extensive functionality in the PDF-XChange Editor SDK and PDF-XChange Core API SDK. It includes all of the PDF-XChange Core API SDK and all of the other layers functionality and also provides access to the Editor level UI. This layer includes the usage of the Operations that provide a versatile problem solving mechanism that is integrated in the Editor. Also, the User Interface itself can be customized and handled appropriately by listening to the Events and redefining the command handlers.
After you've added the PDF-XChange Editor ActiveX Control on your form, you gain access to the IPXV_Control interface that is basically, the wrapper around the IPXV_MainFrame interface with plenty of useful methods and properties that ease the overall SDK usage.
