gsxtxt



PURPOSE

Writes annotated text using the rtfont format.

C SYNTAX

int gsxtxt_ (x, y, number, text)

int *x, *y, *number;
char *text;

FORTRAN SYNTAX

INTEGER function gsxtxt (x, y, number, text)

INTEGER x, y, number
CHARACTER*n text

PASCAL SYNTAX

FUNCTION gsxtxt_ (

VAR x, y, number: INTEGER;
VAR text: ARRAY [1..k] of CHAR
): INTEGER [PUBLIC];

DESCRIPTION

The gsxtxt subroutine displays the specified text string using the rtfont
format.  Only those full or partial characters that fall within the clip box
specified by the gsxtat subroutine are displayed.  In addition, since there is
no default rtfont defined for use by the GSL, the gsxtat subroutine must be
called to set all relevant attributes before the first call to this subroutine.

The relevant attributes are:

  o xtext foreground color
  o xtext background color
  o xtext logical operation
  o xtext clip box
  o xtext current rtfont file
  o plane mask
  o color map.

GSXTXT(3g,L)                AIX Technical Reference                GSXTXT(3g,L)



x, y              Define the baseline position for writing the text.

number            Indicates the number of bytes to write from the text string.

text              Contains the ASCII codes for the characters to write, as an
                  array.

For Pascal, the application must declare the array passed as being fixed length
and declare the routine as accepting an array of that length; the k in the
routine declaration must be a constant.

RETURN VALUE

GS_SUCC  Successful.

Since the text is either displayed or clipped in any case, the gsxtxt
subroutine always completes with a successful return code.
