Embedding watermarks
In Corel DESIGNER, you can also embed Digimarc watermarks in images. First, you must obtain a unique Creator ID by subscribing to
Digimarc’s online service. The Creator ID includes contact details, such as name, phone number, address, email, and web addresses.
Once you have a Creator ID, you can embed a watermark in an image. You can specify the copyright year, image attributes, and the
durability of a watermark. You can also specify the target output method for an image, such as print or the web.
Digimarc watermarks do not prevent unauthorized image use or copyright infringement. But the watermarks do communicate copyright
claims. They also provide contact information for those who want to use or license an image.
For more information about Digimarc, see www.digimarc.com.

Combine all objects with the background before adding a watermark. For more information about combining objects with the

Removing dust and scratch marks from bitmaps
You can quickly improve the appearance of a bitmap by removing dust and scratch marks. The dust and scratch filter works by eliminating
the contrast between pixels that exceed the contrast threshold you set. You can set a radius to determine how many pixels are affected by
