 *

 * PDF/X-5n starter:

 * Create PDF/X-5n conforming output with an image and DeviceN color

 *

 * Required software: PDFlib/PDFlib+PDI/PPS 9.1

 * Required data: font file, image file, n-colorant ('xCLR') ICC output

 *                intent profile

 *               

 * This program uses an n-colorant ICC output intent profile. As there are no

 * freely distributable n-colorant ICC profiles available for download, this

 * example program is disabled by default. To use this program put an

 * n-colorant ICC profile into the "extra_input" directory and assign its

 * name to the "profilename" variable below.

 *

 * This example is not run by default from the Ant build.xml file and can be

 * executed either specifically by invoking "ant starter_pdfx5n" or together

 * with the other topics that require extra configuration by invoking "ant

 * run-extra-topics".
