Comments

You can create a region either by using one of the LEAD functions. Or you can use the tools in the image viewer that draws different shapes of regions, which are:

• Nudge tools region.

• Rectangle region.

• Elliptical region.

• Circurlare region.

• Square region.

• Polygon region.

• Free hand region.

• [18] Magic wand (contiguous color) region

• Color range region.

Tools for drawing regions can be added to the viewer by calling L_DispContainerAddAction, and can be set by calling L_DispContainerSetAction.

For more information about how to create a region using the medical viewer tools. Refer to Creating a Bitmap Region Inside the Image Viewer.
