al_get_text_dimensions(3)                            al_get_text_dimensions(3)

NAME
       al_get_text_dimensions - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro_font.h>

              void al_get_text_dimensions(const ALLEGRO_FONT *f,
                 char const *text,
                 int *bbx, int *bby, int *bbw, int *bbh)

DESCRIPTION
       Sometimes, the al_get_text_width(3) and al_get_font_line_height(3)
       functions are not enough for exact text placement, so this function
       returns some additional information.

       Returned variables (all in pixel):

       o x, y - Offset to upper left corner of bounding box.

       o w, h - Dimensions of bounding box.

       Note that glyphs may go to the left and upwards of the X, in which case
       x and y will have negative values.
