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

This is a SunPHIGS Extension function based on PHIGS+ and is not part of the PHIGS standard.

C Input Parameters

All of the following data types are predefined in phigs.h.

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;

FORTRAN Input Parameters

All of the following data types are predefined in phigs77.h.

COLMOD
The colour model. The predefined values are:

0PINDIRColour Index Specified
1PRGBRed, Green, and Blue
2PCIECIE Colour Model
3PHSVHue, Saturation, and Value
4PHLSHue, Lightness, and Saturation

ICOLR
An integer index into the workstation colour table for determining the polymarker colour. This value is only used if COLMOD is equal to PINDIR.

COLR(3)
An array of reals containing the polymarker colour. This array is unused if COLMOD is equal to PINDIR.

COLR(1) = Red, Hue, etc.
COLR(2) = Green, Saturation, Lightness, etc.
COLR(3) = Blue, Value, Saturation, etc.

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 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, which 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, ∗)
