Process(LEADDocument,IList<PageAlignment>) Method

Summary

Performs field processing on the LEADDocument object.

Syntax

C++/CLI

Python

public void Process( 
   LEADDocument leadDoc, 
   IList<PageAlignment> formAlignment 
)

public:  
   void Process( 
      LEADDocument^ leadDoc, 
      IList<PageAlignment^>^ formAlignment 
   )

def Process(self,leadDoc,formAlignment):

Parameters

leadDoc

The LEADDocument object.

formAlignment

A value that indicates the Form Alignment. It aligns the Master Form's fields to this form field. If it is null, the fields will be aligned based on the image resolution.
