interface Luna::VG::IFontAtlas : public virtual Interface

Base type

• Interface

Member functions

• virtual void clear()=0

  Removes all glyphs in the font atlas, but keeps the internal storage, so that they can be reused to store new glyphs.

• virtual Font::IFontFile * get_font(u32 *index)=0

  Gets the font file data bound to this font atlas.

• virtual void set_font(Font::IFontFile *font, u32 index)=0

  Sets the font bound to this font atlas. The will reset the font atlas.

• virtual R< RHI::IBuffer * > get_shape_buffer()=0

  Gets the shape buffer that stores the glyph contour commands.

• virtual Span< const f32 > get_shape_points()=0

  Gets the shape points data.

• virtual void get_glyph(usize codepoint, usize first_shape_point, usize num_shape_points, RectF *bounding_rect)=0

  Queries the information of the specified glyph, and optionally packs the glyph to this atlas if it is not packed yet.
