Quick Start: Converting a PDF document to PostScript using the web service API

The following C# example converts a PDF document called loan.pdf to a PostScript document called loan.ps. (See Converting PDF Documents to PostScript.)

/*

 * Ensure that you create a .NET client assembly that uses 

 * base64 encoding. This is required to populate a BLOB 

 * object with data or retrieve data from a BLOB object.

 * 

 * For information, see "Invoking LiveCycle ES using Base64 Encoding" 

 * in Programming with LiveCycle ES
