Struct blit::BlitBuffer

pub struct BlitBuffer { /* private fields */ }

A data structure holding a color and a mask buffer to make blitting on a buffer real fast.

Implementations

impl BlitBuffer

pub fn from_buffer<S>(src: &[u32], width: S, alpha_treshold: u8) -> Self

where S: ToPrimitive,

Create a instance from a buffer of RGBA data packed in a single u32.

It’s assumed that the alpha channel in the resulting pixel is properly set. The alpha treshold is the offset point at which an alpha value will be used as either a transparent pixel or a colored one.

pub fn from_iter<I, S>(iter: I, width: S, alpha_treshold: u8) -> Self

where I: Iterator<Item = u32>, S: ToPrimitive,

Create a instance from a iterator of RGBA data packed in a single u32.

It’s assumed that the alpha channel in the resulting pixel is properly set. The alpha treshold is the offset point at which an alpha value will be used as either a transparent pixel or a colored one.

pub fn width(&self) -> u32

Width of the buffer in pixels.

pub fn height(&self) -> u32

Height of the buffer in pixels.

pub fn size(&self) -> Size

Size of the blitbuffer in pixels.

pub fn pixels(&self) -> &[u32]

Get a reference to the pixel data.

pub fn pixels_mut(&mut self) -> &mut [u32]

Get a mutable reference to the pixel data.
