// This example demostrates adding of barcode together with some custom images (e.g. target marks) to PDF document.
// Also shows the manual calculation of barcode size from inches to pixels and document units (points).
// Task: place Code39 barcode of 2" x 3/8" size at 2" from top-right corner and two target marks at 1" from top-right and bottom-left corners.
