.SH NAME
TTF_SetDirection \- Set a global direction to be used for text shaping\[char46]
.SH SYNOPSIS
.nf
.B #include \(dqSDL3_ttf/SDL_ttf.h\(dq
.PP
.BI "int TTF_SetDirection(int direction); /* hb_direction_t */
.fi
.SH DEPRECATED
This function expects an hb_direction_t value, from HarfBuzz, cast to an
int, and affects all fonts globally\[char46] Please use

.BR TTF_SetFontDirection
() instead, which uses an enum
supplied by SDL_ttf itself and operates on a per-font basis\[char46]

This is a global setting; fonts will favor a value set with

.BR TTF_SetFontDirection
(), but if they have not had
one explicitly set, they will use the value specified here\[char46]

The default value is
.BR HB_DIRECTION_LTR
(left-to-right text flow)\[char46]

.SH FUNCTION PARAMETERS
.TP
.I direction
an hb_direction_t value\[char46]
.SH RETURN VALUE
Returns 0, or -1 if SDL_ttf is not compiled with HarfBuzz support\[char46]

.SH AVAILABILITY
This function is available since SDL_ttf 3\[char46]0\[char46]0\[char46]
