GPQMR - Inquire Polymarker Representation

GPQMR (wsid, index, type, errind, mtype, msize, color)

Purpose

Use GPQMR to inquire the current attribute values in the specified entry in the polymarker bundle table of the specified workstation.

If the inquired information is available, then the graPHIGS API sets the error indicator to zero and returns the values in the output parameters. If the inquired information is unavailable, then the error indicator (errind) contains an error number indicating the reason, and the values returned in the output parameters are unpredictable.

Parameters

wsid -- specified by user, fullword integer

Workstation identifier.

index -- specified by user, fullword integer

Polymarker bundle table index (>=1)

type -- specified by user, fullword integer

Type of returned values (1=SET )

errind -- returned by the graPHIGS API, fullword integer

Error indicator. If the error indicator is zero, the request has been completed. Otherwise, one of the following errors exists:

25: SPECIFIED WORKSTATION DOES NOT EXIST
35: WORKSTATION HAS ONLY INPUT CAPABILITIES
43: BUNDLE INDEX EXCEEDS WORKSTATION TABLE CAPACITY
60: BUNDLE INDEX VALUE < ONE
526: REQUESTED DATA NOT AVAILABLE FOR THIS FUNCTION
534: TYPE VALUE IS INVALID

mtype -- returned by the graPHIGS API, fullword integer

Marker type in the specified entry.

msize -- returned by the graPHIGS API, short floating-point number

Marker size scale factor in the specified entry.

color -- returned by the graPHIGS API, fullword integer

Polymarker color index in the specified entry.

Note:

Direct polymarker color returns error indicator 526

Error Codes

None
