Usage

Overview

zoomer automatically generates a video from a picture. It starts at the full picture and then zooms into the first point. Then zooms out and into the next point, etc. At the moment of reaching a point, zoomer will write a text (e.g. a name).

zoomer needs a picture (bigger is better) and a data file to define the points to be zoomed into.
