Creates a new, empty font cache entry resource.
RID _create_font_linked_variation(font_rid: RID) virtual 🔗
Optional, implement if font supports extra spacing or baseline offset.
Creates a new variation existing font which is reusing the same glyph cache and font data.
RID _create_shaped_text(direction: Direction, orientation: Orientation) virtual required 🔗
Creates a new buffer for complex text layout, with the given direction and orientation.
void _draw_hex_code_box(canvas: RID, size: int, pos: Vector2, index: int, color: Color) virtual const 🔗
Draws box displaying character hexadecimal code.
void _font_clear_glyphs(font_rid: RID, size: Vector2i) virtual required 🔗
Removes all rendered glyph information from the cache entry.
void _font_clear_kerning_map(font_rid: RID, size: int) virtual 🔗
