Whether or not the closed graphics element is displayed as filled (in some unspecified manner that shall be distinguishable from an outline) or as an outline. See Section C.10.5.1.2.
Enumerated Values:
- Y
-
yes
- N
-
no
Required if Graphic Data (0070,0022) is "closed", that is Graphic Type (0070,0023) is CIRCLE or ELLIPSE, or Graphic Type (0070,0023) is POLYLINE or INTERPOLATED and the first data point is the same as the last data point.
Section C.10.5.1.2
C.10.5.1.2 Graphic Data and Graphic Type
Graphic Data (0070,0022) contains the points in the graphic annotation, each dimension for the first point, followed by dimensions for second point, etc. For a two dimensional curve: X1, Y1, X2, Y2, etc. The first (X) dimension corresponds to the image or Specified Displayed Area column (horizontal offset), and the second (Y) dimension corresponds to the image or Specified Displayed Area row (vertical offset). The Value Representation of all components of the N-tuple shall be the same. The image or Specified Displayed Area relative drawing space is defined in Graphic Annotation Units (0070,0005).
If Graphic Type (0070,0023) is POINT, then two values (one point) shall be specified and the single point specified is to be drawn.
If Graphic Type (0070,0023) is POLYLINE, then the points are to be interpreted as an n-tuple list of end points between which straight lines are to be drawn.
If Graphic Type (0070,0023) is INTERPOLATED, then the points are to be interpreted as an n-tuple list of end points between which some form of implementation dependent curved lines are to be drawn. The rendered line shall pass through all the specified points.
If Graphic Type (0070,0023) is CIRCLE, then exactly two points shall be present; the first point is to be interpreted as the center and the second point as a point on the circumference of a circle, some form of implementation dependent representation of which is to be drawn.
If Graphic Type (0070,0023) is ELLIPSE, then exactly four points shall be present; the first two points are to be interpreted as the endpoints of the major axis and the second two points as the endpoints of the minor axis of an ellipse, some form of implementation dependent representation of which is to be drawn.
The notion of "open" or "closed" has no inherent meaning in the context of an arbitrary graphic, other than in the condition for the presence of Graphic Filled (0070,0024). The graphic has no semantic notion of an associated observation such as a region of interest, except that which the unformatted text in the same Item may describe.
The choice of pixel value used to represent the graphic on a display is defined in the Graphic Layer Module.
