SET POLYMARKER COLOUR(3P+)  —  Kubota Pacfic Computer Inc. (29 February 1991)

NAME

SET POLYMARKER COLOUR − create a structure element to set the current polymarker colour

SYNOPSIS

C Syntax

void
pset_marker_colr ( colour )
Pgcolr∗colour;polymarker colour

Required PHIGS Operating States

(PHOP, ∗, STOP, ∗)

DESCRIPTION

Purpose

SET POLYMARKER COLOUR creates a structure element to set the current polymarker colour. 

When the current polymarker colour Aspect Source Flag ASF is set to INDIVIDUAL, the current value of this attribute applies to the following output primitives:

• POLYMARKER

• POLYMARKER 3

C Input Parameters

colourPolymarker colour. Pgcolr is defined as:

typedef struct {
Pint type;/∗ indirect, RGB, CIE, HSV, HLS ∗/
union {
   Pintindex;/∗ colour table index ∗/
   struct {
Pfloatx; /∗ red, hue, etc. ∗/
Pfloaty; /∗ green, saturation, lightness, etc. ∗/
Pfloatz; /∗ blue, value, saturation, etc. ∗/
   } general;
} val;
} Pgcolr;

Execution

Depending on the edit mode, a SET POLYMARKER COLOUR element with the value polymarker colour in the specified colour model is inserted into the open structure after the element pointer or it replaces the element pointed at by the element pointer. The element pointer is then updated to point to this SET POLYMARKER COLOUR element. 

When the current polymarker colour ASF is set to INDIVIDUAL, marker output primitives that follow in the structure network are drawn using the current polymarker colour. 

When the current polymarker colour ASF is set to BUNDLED, the polymarker colour is taken from the workstation extended representation indicated by the current polymarker index.  In this case, the polymarker colour set with SET POLYMARKER COLOUR has no effect. 

The standard PHIGS function SET POLYMARKER COLOUR INDEX is equivalent to calling to SET POLYMARKER COLOUR with type INDIRECT. 

ERRORS

005Ignoring function, function requires state (PHOP, ∗, STOP, ∗)
