| - | Usually, when you see formats as (.mp4) it means that you have a set of images and a sound file tied together. Movies produced by the Map Viewer follow the same definition. The user is required to load the maps (which are going to be the images in the movie) he wants to display and then configure the viewer main area as if it was the movie itself. Transformations (zoom, pan) are kept on the movie, as well as histogram curves, palettes for each images and transparency. | + | Usually, when you see formats as (.mp4) it means that you have a set of images and a sound file tied together.
