AnimatedClip
Multi image formats (GIF and TIFF) demo using RasterPlayer
This example demonstrates how to use RasterPlayer class to show animated GIFs or multipage TIFFs.
It can be compiled as "GUI" or "GUI MT". In the second case RasterPlayer can work in the same thread or opening a new thread. This can be defined with SetMT() method.
