Classes
struct	fl::gfx::Canvas< RGB_T >
	Simple rectangular canvas for graphics operations Combines a pixel buffer with dimensions for cache-optimal drawing. More...
struct	fl::gfx::CanvasMapped< RGB_T >
	XYMap-backed canvas for non-rectangular or remapped layouts. More...

Namespaces
namespace	fl
	Base definition for an LED controller.
namespace	fl::gfx

Enumerations
enum class	fl::gfx::LineCap { fl::gfx::FLAT , fl::gfx::ROUND , fl::gfx::SQUARE }
	Line cap styles for stroke operations. More...
