text_precision(3G)

NAME

text_precision − select how text will be drawn.

SYNOPSIS

C Syntax:

void text_precision(fildes,precision);
int fildes, precision;

FORTRAN77 Syntax:

subroutine text_precision(fildes,precision)
integer*4 fildes,precision

Pascal Syntax:

procedure text_precision(fildes,precision:integer);

DESCRIPTION

Input Parameters

fildes Integer file descriptor returned by gopen when an I/O path to a graphics device is opened.

precision One of the values

STRING_TEXT
CHARACTER_TEXT
STROKE_TEXT

Discussion

Text_precision selects the method by which subsequent text strings are drawn. If STRING_TEXT is selected, the device’s text capabilities are used. Hardware text generation, in general, provides only limited approximations to the actual text-size attributes which may have been set. Text attributes for hardware text may need to be set directly on the device by sending escape codes using a GESCAPE call. Consult the device’s reference manual for a list of these escape codes.

STROKE_TEXT causes characters to be drawn at a higher precision than hardware text, but at a slower rate on some devices.

Currently, STROKE_TEXT precision is used for CHARACTER_TEXT precision.

DEFAULTS

precision = STROKE_TEXT
