TilePicture class

A container for either a ui.Picture (a recorded sequence of drawing commands) or a ui.Image (raw pixel data).

This class is used to represent a rendered map tile. It can be created from either a picture or a bitmap, and it handles the disposal of the underlying graphics resources. It is crucial to call dispose when the tile is no longer needed.
