The bag's picture above, don't know if canvas painting, my question is:

The lattice of upload pictures, how do I use the mouse to control the size of it and put the position? Is also implemented using canvas? Open source projects have ready

Directly with canvas words is relatively easy to control, operate the image coordinates, according to the movement of the mouse

The picture of the bag is used as the background, upload images using a drag and drop support, rotation, scaling of plug-in, record the location, Angle and zoom multiples
