INQUIRE EDGE REPRESENTATION PLUS

PQEDP


CALL SEQUENCE

CALL PQEDP	(WKID, EDI, CCSBSZ, TYPE, ERRIND, EDFLAG, EDTYPE, EWIDTH, CTYPE,COLI,NCC,COLR)

INPUT PARAMETERS

INTEGER WKID
Workstation identifier
INTEGER EDI
Edge index
INTEGER CCSBSZ
Colour component specification buffer size
INTEGER TYPE
Type of return value(PSET,PREALI)

OUTPUT PARAMETERS

INTEGER ERRIND
Error indicator
INTEGER EDFLAG
Edge flag (POFF,PON)
INTEGER EDTYPE
Edge type
RREAL EWIDTH
Edge scale factor
INTEGER CTYPE
Colour type
INTEGER COLI
Colour index
INTEGER NCC
Number of components of colour value
RREAL COLR(CCSBSZ)
Colour components

PHIGS STATE

(PHOP, WSOP,*,*)

EFFECT

Returns the components contained in the specified edge representation of the edge table in workstation WKID's workstation state list. If the data is available, error indicator is returned as 0.

If the inquired information is available, the error indicator is returned as 0 and values are returned in the output parameters.

If the specified edge index is not present in the edge bundle table, and the specified type of returned value is REALIZED, the representation for edge index 1 is returned.

If the inquired information is not available, the values returned in the output parameters are implementation dependent and the error indicator is set to one of the following error numbers to indicate the reason for non-availability:

ERRORS

3
Ignoring function, function requires state (PHOP, WSOP,*,*)
54
Ignoring function, the specified workstation is not open
59
Ignoring function, the specified workstation does not have output capability (i.e. the workstation category is neither OUTPUT, OUTIN, nor MO)
100
Ignoring function, the bundle index value is less than one
101
Ignoring function, the specified representation has not been definded
