Using Digimarc watermarks to identify bitmaps
A Digimarc watermark embeds copyright details, contact information, and image attributes in an image. A watermark makes subtle changes
to the brightness of pixels in an image. These changes cannot be readily seen; however, at high magnification, you might notice changes in
the brightness of some pixels. Digimarc watermarks aren’t affected by normal editing, printing, and scanning.
Detecting watermarks
When you open an image in Corel DESIGNER, you can check for a watermark. If a watermark is present, a copyright symbol appears on the
title bar. You can find information about the watermarked image by reading the embedded message and by linking to the contact profile in
the Digimarc database.
