STRINGSIZE(2) STRINGSIZE(2) NAME stringsize, stringwidth, stringnwidth, runestringsize, runestringwidth, runestringnwidth - graphical size of strings SYNOPSIS #include <u.h> #include <libc.h> #include <draw.h> Point stringsize(Font *f, char *s) int stringwidth(Font *f, char *s) int stringnwidth(Font *f, char *s, int n) Point runestringsize(Font *f, Rune *s) int runestringwidth(Font *f, Rune *s) int runestringnwidth(Font *f, Rune *s, int n) DESCRIPTION These routines compute the geometrical extent of character strings when drawn on the display. The most straightfor- ward, stringsize, returns a Point representing the vector from upper left to lower right of the NUL-terminated string s drawn in font f. Stringwidth returns just the x component. Stringnwidth returns the width of the first n characters of s. The routines beginning with rune are analogous, but accept an array of runes rather than UTF-encoded bytes. FILES /lib/font/bit directory of fonts SOURCE /sys/src/libdraw SEE ALSO addpt(2), cachechars(2), subfont(2), draw(2), draw(3), image(6), font(6) DIAGNOSTICS Because strings are loaded dynamically, these routines may generate I/O to the server and produce calls to the graphics error function.
