Package: zen_api.lm.acquisition.v2

Message `RegionContour`#

General data contract for all region contour types.

Field	Number	Type	Presence	Description
`name`	1	`string`	singular	The region contour name.
`region_ellipse`	10	zen_api.lm.acquisition.v2.RegionEllipse	oneof `subtype`
`region_rectangle`	11	zen_api.lm.acquisition.v2.RegionRectangle	oneof `subtype`
`region_polygon`	12	zen_api.lm.acquisition.v2.RegionPolygon	oneof `subtype`

Represents an elliptical region defined by a bounding rectangle.

Field	Number	Type	Presence	Description
`bounding_box`	1	zen_api.lm.acquisition.v2.RegionRect	singular	The rectangle that defines the bounding box of the ellipse. The ellipse is fully contained within this rectangle. The ZenApi.LM.Acquisition.V2.RegionRect specifies the position and size of the bounding rectangle using four values: X (left), Y (top), Width, and Height. For example, a rectangle with X = 10, Y = 20, Width = 100, and Height = 50 defines an ellipse centered at (60, 45) with a horizontal radius of 50 and a vertical radius of 25.

Represents a polygonal region defined by an ordered list of vertices.

Field	Number	Type	Presence	Description
`points`	1	zen_api.lm.acquisition.v2.RegionPoint	repeated	The ordered list of ZenApi.LM.Acquisition.V2.RegionPoint instances that define the vertices of the polygon. Each point specifies an (X, Y) coordinate in the region's coordinate space. The polygon is formed by connecting each consecutive point in the list, and finally connecting the last point back to the first to close the shape.

Represents a rectangular region within the scan area.

Field	Number	Type	Presence	Description
`rectangle`	1	zen_api.lm.acquisition.v2.RegionRect	singular	The ZenApi.LM.Acquisition.V2.RegionRect that defines the position and size of the rectangular region within the scan area.
