Member Variables

  • float ascent - Ascent (number of pixels above the baseline).
  • bool distance_field - If true distance field hint is enabled.
  • BitmapFont fallback - The fallback font.
  • float height - Total font height (ascent plus descent) in pixels.

Description

Renders text using \*.fnt fonts containing texture atlases. Supports distance fields. For using vector font files like TTF directly, see DynamicFont.

Member Function Description

Adds a character to the font, where character is the unicode value, texture is the texture index, rect is the region in the texture (in pixels!), align is the (optional) alignment for the character and advance is the (optional) advance.

  • void add_kerning_pair ( int char_a, int char_b, int kerning )

Adds a kerning pair to the BitmapFont as a difference. Kerning pairs are special cases where a typeface advance is determined by the next character.

  • void add_texture ( Texture texture )

Adds a texture to the BitmapFont.

  • void clear ( )

Clears all the font data and settings.

Creates a BitmapFont from the \*.fnt file at path.

Returns the size of a character, optionally taking kerning into account if the next character is provided.

  • int get_kerning_pair ( int char_a, int char_b ) const

Returns a kerning pair as a difference.

Returns the font atlas texture at index idx.

  • int get_texture_count ( ) const

Returns the number of textures in the BitmapFont atlas.
