Quick Start: Converting a PDF document to JPEG files using the Java API

The following Java code example converts a PDF document called Loan.pdf to a set of JPEG files and stores them in the C:\Adobe directory. Each file is named tempFile[index].jpg, where the first image file is named tempFile0.jpg. (See Converting PDF Documents to Image Formats.)

/*

 * This Java Quick Start uses the following JAR files

 * 1. adobe-convertpdf-client.jar

 * 2. adobe-livecycle-client.jar

 * 3. adobe-usermanager-client.jar

 * 4. adobe-utilities.jar

 * 5. jbossall-client.jar (use a different JAR file if LiveCycle ES is not deployed on JBoss)

 * 

 *  These JAR files are located in the following path:

 * <install directory>/Adobe/LiveCycle8/LiveCycle_ES_SDK/client-libs

 * 

 * For complete details about the location of these JAR files, 

 * see "Including LiveCycle ES library files" in Programming

 * with LiveCycle ES
