Using the signal strength meter

The signal strength meter helps you determine whether a watermark is durable enough to survive the intended use of the image. The signal strength meter is available only for images containing watermarks that you yourself have embedded.

Digimarc recommends that you check the signal strength meter before publishing your images. For example, if you often compress watermarked images for inclusion in a Web site, check the meter before posting the images. You can also use the signal strength meter to gauge the effectiveness of different Watermark Durability settings that you are experimenting with.

To check the signal strength meter:

Choose Filter > Digimarc > Read Watermark. The signal strength meter appears at the bottom of the dialog box.

You can also display the meter automatically by selecting Verify while embedding the watermark. (See Embedding digital watermarks.)
