Primitive (pr) Resources

prGraphicStyle

This resource specifies the id of a GraphicStyle object used to determine the attributes of the the graphics primitive. If set to NullObjId a default graphicstyle will apply to the primitive. This may be either the default Workstation graphicstyle or a graphicstyle determined in some other way.

Default: NullObjId

prPolyType

This resource of type NhlTPolyType specifies the type of the graphic primitive. Currently there are three choices:

Polyline

The graphics primitive will be rendered as a series of connected lines. You define the line attributes by setting resources whose names begin with gsLine... in the associated graphic style object.

Polygon

The graphics primitive will be rendered as an edge consisting of closed series of connected lines enclosing a filled area. You define the edge attributes by setting resources whose names begin with gsEdge... in the associated graphic style object. Likewise, you define the fill attributes by setting resources whose names begin with gsFill....

Polymarker

The graphics primitive will be rendered as a series of marker symbols drawn at each of the coordinate points. You define the marker attributes by setting resources whose names begin with gsMarker... in the associated graphic style object.

Default: Polyline

prXArray

This array resource specifies the data space X coordinates of the points that define the graphic primitive.

Default: NULL

prYArray

This array resource specifies the data space Y coordinates of the points that define the graphic primitive.

Default: NULL
