Low Level Coordinate System for WPF Annotations

Note: This topic is for Document/Medical only.

The coordinates for defining and positioning LEADTOOLS annotations are stored in floating point values that are translated to device coordinates only when the annotations are displayed. Each annotation object is defined and positioned relative to its container. The root container sets the frame of reference. This system provides flexibility in storing and transporting annotations. You can set the root container's width and height to arbitrary measurements, such as 1000 by 1000, that you adjust when applying the container's annotations to a bitmap image.
