Abstract:
1. A method of encoding a watermark into an image for rendering on an image output device, the image output device associated with a pixel grid including a first predetermined number of substantially equally spaced pixels in a first direction, and a second predetermined number of substantially equally spaced pixels in a second direction for rendering the image, the method comprising: a) generating a pixel data representation of the image for rendering on the image output device; b) modulating the pixel spacing of one of the first predetermined number of pixels and the second predetermined number of pixels to encode the watermark within a rendering of the pixel data representation using the image output device; and, c) one of rendering the image including the encoded watermark, further processing the pixel data representation of the image including the encoded watermark, and storing the pixel data representation of the image including the encoded watermark.
