Detailed Description

BitmapImage is the basic runtime primitive to load, hold, and convert image data in memory.

Each image has width, height, pixel format, image data in memory, and can contain mipmap images.

To display an image, you must create a texture instance from that image. When you do so, you must transfer the ownership of the image to the texture instance using com.rightware.kanzi.TextureBuilder.
