.SH DESCRIPTION
.SS Purpose
\s-2SET TEXT COLOUR\s+2 creates a structure element to set the text
colour attribute.
.LP
When the current interior shading
method Aspect Source Flag
(\s-2ASF\s+2) is set to \s-2INDIVIDUAL\s+2, the current value of
this attribute applies to the following output primitives:

Text colour. Pgcolr is defined as:

.nf
.sp .4
typedef struct {
.sp .2
Pint type; /* indirect, RGB, CIE, HSV, HLS */
union {
Pint ind; /* colour table index */
struct {
Pfloat x; /* red, hue, etc. */
Pfloat y; /* green, saturation, lightness, etc. */
Pfloat z; /* blue, value, saturation, etc. */
} general;
} val;
} Pgcolr;
.fi
.SS Execution
Depending on the edit mode, a \s-2SET TEXT COLOUR\s+2 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 \s-2SET TEXT COLOUR\s+2 element.
.LP
When the current text colour \s-2ASF\s+2 is set to
\s-2INDIVIDUAL\s+2, text output primitives
that follow in
the structure network are drawn using the current
text colour.
.LP
When the current text colour \s-2ASF\s+2 is set to \s-2BUNDLED\s+2,
the text colour is taken from the
workstation extended representation indicated by the current text index.
In this case, the text colour
set with \s-2SET TEXT COLOUR\s+2 has no effect.
.LP
The standard \s-2PHIGS\s+2 function \s-2SET TEXT COLOUR INDEX\s+2
is equivalent to calling to \s-2SET TEXT COLOUR\s+2 with type
\s-2INDIRECT\s+2.
