Load Method

Summary

Loads this PDFFile object and populate its pages collection and document properties.

Syntax

C++/CLI

Java

Python

public void Load()

public void load();

public: 
void Load();

def Load(self):

Remarks

This method will load the PDF file set in FileName (using the password set in Password if the PDF file is secured) and populate the following properties:

The Pages property will contain a list of PDFFilePage for each page in the PDF file.
The DocumentProperties property will contain the properties of the PDF file.

This method will fail with an exception if the file in FileName is not a valid PDF file. However, it is possible to use the name of a Postscript file in FileName, and then call the Distill method (but in such a situation, do not call Load).
