.SH NAME
XmbTextEscapement, XwcTextEscapement, Xutf8TextEscapement \- obtain the escapement of text
.SH SYNTAX
.HP
int XmbTextEscapement\^(\^XFontSet \fIfont_set\fP\^, char *\fIstring\fP\^, int
\fInum_bytes\fP\^);
.HP
int XwcTextEscapement\^(\^XFontSet \fIfont_set\fP\^, wchar_t *\fIstring\fP\^,

.HP
int Xutf8TextEscapement\^(\^XFontSet \fIfont_set\fP\^, char *\fIstring\fP\^,
int \fInum_bytes\fP\^);
.SH ARGUMENTS
.IP \fIfont_set\fP 1i
Specifies the font set.
.IP \fInum_bytes\fP 1i
Specifies the number of bytes in the string argument.
.IP \fInum_wchars\fP 1i
Specifies the number of characters in the string argument.
.IP \fIstring\fP 1i
Specifies the character string.
.SH DESCRIPTION
The
.ZN XmbTextEscapement ,
.ZN XwcTextEscapement
and
.ZN Xutf8TextEscapement
functions return the escapement in pixels of the specified string as a value,
using the fonts loaded for the specified font set.
The escapement is the distance in pixels in the primary draw
direction from the drawing origin to the origin of the next character to
be drawn, assuming that the rendering of the next character is not
dependent on the supplied string.
.LP
Regardless of the character rendering order,
the escapement is always positive.
.LP
The function
.ZN Xutf8TextEscapement
is an extension introduced by The XFree86 Project, Inc. in their 4.0.2
release. Its presence is
indicated by the macro
.ZN X_HAVE_UTF8_STRING .
