The Image Manipulator is a viewer that can be used to transform an image based on the value of a signal. It allows you to either move, rotate, scale and/or transparentize an image using so called manipulations. By combining images, signals and manipulations a user is able to create new viewers to be used in a layout.
A move manipulation can be used to change an images X and Y position using pixels.
