Summary

Gets or sets the 1-based index of the last page associated with this PDFPageRangeFromStream.

Syntax

C++/CLI

Java

Python

public int LastPageNumber

public int LastPageNumber;

public: 
property int LastPageNumber;

LastPageNumber (PDFPageRangeFromStream)

Property Value

An integer number indicating the last page to merge using PDFFile.MergeFiles(PDFPageRangeFromStream[],Stream). You can set this value to -1, which indicates the last page in the file. Otherwise, this value should be greater than or equal to PDFPageRangeFromStream.FirstPageNumber.

Remarks

The first page to merge is indicated by PDFPageRangeFromStream.FirstPageNumber.

This property indicates the last page that would be merged. So, if you wish to merge pages 1 and 2, set PDFPageRangeFromStream.FirstPageNumber to 1 and LastPageNumber to 2.

If you wish to merge only one page (for example 3), you would set PDFPageRangeFromStream.FirstPageNumber and LastPageNumber to 3.
