Return Values

Sample XML string will look like the following:

<?xml version="1.0" encoding="utf-8" ?>
<Hyperlink id="1" page="0" left="50" top="80" right="370" bottom="100" url="http://www.bcltechnologies.com/"/>
<Hyperlink id="2" page="1" left="60" top="90" right="380" bottom="120" url="http://www.pdfonline.com/"/>
<Hyperlink id="3" page="3" left="70" top="100" right="390" bottom="120" url="http://www.bcltechnologies.com/"/>


Note: New attributes can be added to Hyperlink element if needed.
Assumption: The user needs to know how to parse data from an XML string.

For those who are familiar with ExtractAllHyperlinks from the PDFProcessor object, note that this version of ExtractAllHyperlinks from the PDFProcessorHandle object does not take an optional password argument for working with encrypted PDF files. If and when PDFProcessorHandle is enhanced to support processing of encrypted PDF files, the password required will be taken by OpenFile or OpenMem at the time the PDFProcessorHandle is obtained.

Example Usage in VBScript

Set oProcessor = CreateObject("easyPDF.PDFProcessor.8")

Set oProcessorHandle = oProcessor.OpenFile("C:\test\input.pdf", "C:\test\input.pdf")

hyperlinks = oProcessorHandle.ExtractAllHyperlinks

MsgBox hyperlinks

Example Usage in VB.NET

Dim oProcessor As PDFProcessor = New PDFProcessor
Dim oProcessorHandle As PDFProcessorHandle = oProcessor.OpenFile("C:\test\input.pdf", "C:\test\input.pdf")
   Dim hyperlinks As String = oProcessorHandle.ExtractAllHyperlinks()

Example Usage in C#

PDFProcessor oProcessor = new PDFProcessor();
PDFProcessorHandle oProcessorHandle = oProcessor.OpenFile(@"C:\test\input.pdf", @"C:\test\input.pdf", null);
   string hyperlinks = oProcessorHandle.ExtractAllHyperlinks();
