Hi, I was reading the spec part about ImageData [1].
1) I noticed that createImageData() is explicit that it represent a transparent black rectangle. The constructor for ImageData is not that explicit. 2) The last step of the 2nd constructor that takes an Uint8ClampedArray says: " • Return a new ImageData object whose width is sw, whose height is height, and whose data is source.” Is data a reference to the original source or a copy of source? For the former, there might be two ImageData objects referencing the same ByteArray. How would that be useful? Greetings, Dirk [1] http://www.whatwg.org/specs/web-apps/current-work/multipage/the-canvas-element.html#dfnReturnLink-7 (4.12.4.2.16 Pixel manipulation)
