The capacity of the watermark is the same as the capacity of the image. This could, of course, result in massive changes to the appearance of the image, but change in the appearance of the image has never been prohibited in "watermarking".

Note: the number of bytes per array location is 1 for uint8, 2 for uint16, and 8 for double.

the capacity is the size of your image, i mean the number of bits in your watermark
