Implementations

impl<'a> SuperBlitter<'a>

fn new( bounds: &IntRect, clip_rect: &ScreenIntRect, blitter: &'a mut dyn Blitter, ) -> Option<Self>

fn flush(&mut self)

Once runs contains a complete supersampled row, flush() blits it out through the wrapped blitter.

Trait Implementations

impl Blitter for SuperBlitter<'_>

fn blit_h(&mut self, x: u32, y: u32, width: NonZeroU32)

Blits a row of pixels, with location and width specified in supersampled coordinates.

fn blit_anti_h( &mut self, _x: u32, _y: u32, _antialias: &mut [u8], _runs: &mut [Option<NonZeroU16>], )

Blits a horizontal run of antialiased pixels.

fn blit_v(&mut self, _x: u32, _y: u32, _height: NonZeroU32, _alpha: u8)

Blits a vertical run of pixels with a constant alpha value.

fn blit_anti_h2(&mut self, _x: u32, _y: u32, _alpha0: u8, _alpha1: u8)

fn blit_anti_v2(&mut self, _x: u32, _y: u32, _alpha0: u8, _alpha1: u8)

fn blit_rect(&mut self, _rect: &ScreenIntRect)

Blits a solid rectangle one or more pixels wide.

fn blit_mask(&mut self, _mask: &Mask, _clip: &ScreenIntRect)

Blits a pattern of pixels defined by a rectangle-clipped mask.

impl Drop for SuperBlitter<'_>

fn drop(&mut self)

Executes the destructor for this type.
