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.
