Struct PixelView 

pub struct PixelView<'a> { /* private fields */ }

A read-only view of somebody else’s pixels, for Canvas::copy_from.

Implementations

impl<'a> PixelView<'a>

pub fn new(pixels: &'a [u32], size: Size, stride: u32) -> Option<PixelView<'a>>

Wraps a pixel slice. Returns None if pixels is too small for the geometry, or if stride is narrower than size.width.

pub fn from_frame(frame: &'a Frame<'_>) -> Option<PixelView<'a>>

Borrows a frame’s pixels for reading.

pub const fn size(&self) -> Size

Visible extent.

pub fn row(&self, y: i32, x0: i32, x1: i32) -> Option<&[u32]>

The pixels of row y from x0 to x1, or None if that span falls outside the view.
