+.SH ARGUMENTS
+.IP \fIdirection_return\fP 1i

+Specifies the connection to the X server.
+.IP \fIfont_ID\fP 1i
+Specifies either the font ID or the
+.ZN GContext
+ID that contains the font.
+.IP \fIfont_ascent_return\fP 1i
+Returns the font ascent.
+.IP \fIfont_descent_return\fP 1i
+Returns the font descent.
+.IP \fIfont_struct\fP 1i
+Specifies the
+.ZN XFontStruct
+structure.
+.IP \fInchars\fP 1i
+Specifies the number of characters in the character string.
+.IP \fIstring\fP 1i
+Specifies the character string.
+.IP \fIoverall_return\fP 1i
+Returns the overall size in the specified
+.ZN XCharStruct
+structure.
+.SH DESCRIPTION
+The
+.ZN XTextExtents
+and
+.ZN XTextExtents16
+functions
+perform the size computation locally and, thereby,
+avoid the round-trip overhead of
+.ZN XQueryTextExtents
+and
+.ZN XQueryTextExtents16 .
+Both functions return an
+.ZN XCharStruct
+structure, whose members are set to the values as follows.
+.LP
+The ascent member is set to the maximum of the ascent metrics of all
+characters in the string.
+The descent member is set to the maximum of the descent metrics.
+The width member is set to the sum of the character-width metrics of all
+characters in the string.
+For each character in the string,
+let W be the sum of the character-width metrics of all characters preceding
+it in the string.
+Let L be the left-side-bearing metric of the character plus W.
+Let R be the right-side-bearing metric of the character plus W.
+The lbearing member is set to the minimum L of all characters in the string.
+The rbearing member is set to the maximum R.
+.LP
+For fonts defined with linear indexing rather than 2-byte matrix indexing,
+each
+.ZN XChar2b
+structure is interpreted as a 16-bit number with byte1 as the
+most significant byte.
+If the font has no defined default character,
+undefined characters in the string are taken to have all zero metrics.
+.LP
+The
+.ZN XQueryTextExtents
+and
+.ZN XQueryTextExtents16
+functions return the bounding box of the specified 8-bit and 16-bit
+character string in the specified font or the font contained in the
+specified GC.
+These functions query the X server and, therefore, suffer the round-trip
+overhead that is avoided by
+.ZN XTextExtents
+and
+.ZN XTextExtents16 .
+Both functions return a
+.ZN XCharStruct
+structure, whose members are set to the values as follows.
+.LP
+The ascent member is set to the maximum of the ascent metrics
+of all characters in the string.
+The descent member is set to the maximum of the descent metrics.
+The width member is set to the sum of the character-width metrics
+of all characters in the string.
+For each character in the string,
+let W be the sum of the character-width metrics of all characters preceding
+it in the string.
+Let L be the left-side-bearing metric of the character plus W.
+Let R be the right-side-bearing metric of the character plus W.
+The lbearing member is set to the minimum L of all characters in the string.
+The rbearing member is set to the maximum R.
+.LP
+For fonts defined with linear indexing rather than 2-byte matrix indexing,
+each
+.ZN XChar2b
+structure is interpreted as a 16-bit number with byte1 as the
+most significant byte.
+If the font has no defined default character,
+undefined characters in the string are taken to have all zero metrics.
+.LP
+Characters with all zero metrics are ignored.
+If the font has no defined default_char,
+the undefined characters in the string are also ignored.
+.LP
+.ZN XQueryTextExtents
+and
+.ZN XQueryTextExtents16
+can generate
+.ZN BadFont
+and
+.ZN BadGC
+errors.
+.SH DIAGNOSTICS
+.TP 1i
+.ZN BadFont
+A value for a Font or GContext argument does not name a defined Font.
+.TP 1i
+.ZN BadGC
+A value for a GContext argument does not name a defined GContext.
