Table 10.38-1. Outline Definition Macro Attributes

Attribute Name	Tag	Type	Attribute Description
Outline Shape Type	(0018,1630)	1	Type of shape of the outline. Enumerated Values: RECTANGULAR CIRCULAR POLYGONAL See Section 10.38.1.1.
Outline Left Vertical Edge	(0018,1631)	1C	X-coordinate in mm of the left edge of the rectangular outline (parallel to the y-axis of the coordinate system). Required if Outline Shape Type (0018,1630) is RECTANGULAR. See Section 10.38.1.2.
Outline Right Vertical Edge	(0018,1632)	1C	X-coordinate in mm of the right edge of the rectangular outline (parallel to the y-axis of the coordinate system). Required if Outline Shape Type (0018,1630) is RECTANGULAR. See Section 10.38.1.2.
Outline Upper Horizontal Edge	(0018,1633)	1C	Y-coordinate in mm of the upper edge of the rectangular outline (parallel to the x-axis of the coordinate system). Required if Outline Shape Type (0018,1630) is RECTANGULAR. See Section 10.38.1.2.
Outline Lower Horizontal Edge	(0018,1634)	1C	Y-coordinate in mm of the lower edge of the rectangular outline (parallel to the x-axis of the coordinate system). Required if Outline Shape Type (0018,1630) is RECTANGULAR. See Section 10.38.1.2.
Center of Circular Outline	(0018,1635)	1C	Location (x,y) in mm of the center of the circular outline. Required if Outline Shape Type (0018,1630) is CIRCULAR. See Section 10.38.1.2.
Diameter of Circular Outline	(0018,1636)	1C	Diameter in mm of the circular outline. Required if Outline Shape Type (0018,1630) is CIRCULAR. See Section 10.38.1.2.
Number of Polygonal Vertices	(0018,1637)	1C	Number of Vertices in Vertices of the Polygonal Outline (0018,1638). Required if Outline Shape Type (0018,1630) is POLYGONAL.
Vertices of the Polygonal Outline	(0018,1638)	1C	A data stream of pairs of x and y in mm. Polygonal outlines are implicitly closed from the last vertex to the origin vertex and all edges shall be non-intersecting except at the vertices. Any given vertex shall occur only once in the data stream. Required if Outline Shape Type (0018,1630) is POLYGONAL. The number of pairs in this data stream shall equal the value of Number of Polygonal Vertices (0018,1637). See Section 10.38.1.2.

10.38.1 Outline Definition Macro Attribute Description
