PedrozaThumbnail Extension
Hello! Here I present to you my fourth extension ever created! This extension provides tools to extract thumbnails from an image or a video.
Background
There isn’t a deep background for this extension as the previous one. It all started when a friend asked me how to get the thumbnail of a video to use it in his app, and I told him that I could try a way, and here it is! I hope you can find it useful. If you find how to make it better, please let me know so I can learn from it!

For reference of the classes used in this extension, please consider reading the Android Developer’s Reference for Android about the ThumbnailUtils class.

Blocks for getting a thumbnail with 150x150 pixels in size and 100 percent quality from an image displayed in an Image1 component when clicking Button1.
