Keep in mind the following considerations before embedding a digital watermark in your image.
Color variation The image must contain some degree of variation or randomness in color to embed the watermark effectively and imperceptibly. The image cannot consist mostly or entirely of a single flat color.
Pixel dimensions The Digimarc technology requires a minimum number of pixels to work. Digimarc recommends the following minimum pixel dimensions for the image to be watermarked:
• 100 pixels by 100 pixels if you don't expect the image to be modified or compressed prior to its actual use.
