Font contains an unicode compatible character set, as well as the ability to draw it with variable width, ascent, descent and kerning. For creating fonts from TTF files (or other font formats), see the editor support for fonts. TODO check wikipedia for graph of ascent/baseline/descent/height/etc.
- void set_height ( real px )
Set the total font height (ascent plus descent) in pixels.
- real get_height ( ) const
Return the total font height (ascent plus descent) in pixels.
- void set_ascent ( real px )
Set the font ascent (number of pixels above the baseline).
- real get_ascent ( ) const
Return the font ascent (number of pixels above the baseline).
- real get_descent ( ) const
Return the font descent (number of pixels below the baseline).
Add a kerning pair to the font as a difference. Kerning pairs are special cases where a typeface advance is determined by the next character.
Return a kerning pair as a difference. Kerning pairs are special cases where a typeface advance is determined by the next character.
- void add_texture ( Texture texture )
Add a texture to the font.
- void add_char ( int character, int texture, Rect2 rect, Vector2 align=Vector2(0,0), real advance=-1 )
Add 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.
Return the size of a character, optionally taking kerning into account if the next character is provided.
Return the size of a string, taking kerning and advance into account.
- void clear ( )
Clear all the font data.
- void draw ( RID canvas_item, Vector2 pos, String string, Color modulate=Color(1,1,1,1), int clip_w=-1 ) const
Draw "string" into a canvas item using the font at a given "pos" position, with "modulate" color, and optionally clipping the width. "pos" specifies te baseline, not the top. To draw from the top, //ascent// must be added to the Y axis.
- real draw_char ( RID canvas_item, Vector2 pos, int char, int next=-1, Color modulate=Color(1,1,1,1) ) const
Draw character "char" into a canvas item using the font at a given "pos" position, with "modulate" color, and optionally kerning if "next" is apassed. clipping the width. "pos" specifies te baseline, not the top. To draw from the top, //ascent// must be added to the Y axis. The width used by the character is returned, making this function useful for drawing strings character by character.
