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

NAME

SET TEXT COLOUR − create a structure element to set the text colour attribute

SYNOPSIS

C Syntax

void
pset_text_colr ( colour )
Pgcolr∗colour;text colour

Required PHIGS Operating States

(PHOP, ∗, STOP, ∗)

DESCRIPTION

Purpose

SET TEXT COLOUR creates a structure element to set the text colour attribute.

When the current interior shading method Aspect Source Flag (ASF) is set to INDIVIDUAL, the current value of this attribute applies to the following output primitives:

• TEXT

• TEXT 3

• ANNOTATION TEXT RELATIVE

• ANNOTATION TEXT RELATIVE 3

C Input Parameters

colourText colour. Pgcolr is defined as:

typedef struct {
Pint type;/∗ indirect, RGB, CIE, HSV, HLS ∗/
union {
   Pintind;/∗ 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 TEXT COLOUR element with the value text 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 TEXT COLOUR element.

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

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

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

ERRORS

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