Features

  1. Using a text to stamp
  2. you can rotate the stamp in any rotate
  3. add watermark to any html elements,so you can add different watermarks in a web page

Defact

  1. watermark will set the position of the element for relative which contain the watermark
  2. when you set abnormal options of the wartemark like font:'226px serif',rotate:13/24*Math.PI.the watermark will only show a part of it and you could fix the issue by set yOffset which control the start point of the text.
