GPCR2 - Circle 2

GPCR2 (center, radius)

Purpose

Use GPCR2 to insert a Circle 2 structure element into the open structure following the element pointer or to replace the element pointed at by the element pointer with a Circle 2 structure element depending on the current edit mode.

GPCR2 draws a line and uses the polyline attributes.

GPCR2 is identified as GDP 1005.

Note:

Not all GDPs are supported on all workstations. Use the Inquire List of Generalized Drawing Primitives (GPQGD) subroutine to determine the GDPs supported by an opened workstation. See also the workstation description in The graPHIGS Programming Interface: Technical Reference

Parameters

center -- specified by user, 2 short floating-point numbers (MC)

Center of circle.

radius -- specified by user, short floating-point number (MC)

Radius of circle (>=0)

Error Codes

5: FUNCTION REQUIRES STATE STOP OR NROP (NOT STCL)
582: RADIUS SPECIFIED < ZERO
