NAME

ALLEGRO_GLYPH - Allegro 5 API

SYNOPSIS

#include <allegro5/allegro_font.h>
typedef struct ALLEGRO_GLYPH ALLEGRO_GLYPH;

DESCRIPTION

A structure containing the properties of a character in a font.

typedef struct ALLEGRO_GLYPH {
   ALLEGRO_BITMAP *bitmap;   // the bitmap the character is on
   int x;                    // the x position of the glyph on bitmap
   int y;                    // the y position of the glyph on bitmap
   int w;                    // the width of the glyph in pixels
   int h;                    // the height of the glyph in pixels
   int kerning;              // pixels of kerning (see below)
   int offset_x;             // x offset to draw the glyph at
   int offset_y;             // y offset to draw the glyph at
   int advance;              // number of pixels to advance after this character
} ALLEGRO_GLYPH;

bitmap may be a sub-bitmap in the case of color fonts. Bitmap can also be NULL in which case nothing should be drawn (sometimes true for whitespace characters in TTF fonts).

kerning should be added to the x position you draw to if you want your text kerned and depends on which codepoints al_get_glyph(3) was called with.

Glyphs are tightly packed onto the bitmap, so you need to add offset_x and offset_y to your draw position for the text to look right.

advance is the number of pixels to add to your x position to advance to the next character in a string and includes kerning.
