Struct ImageAccessorWrap 

pub struct ImageAccessorWrap<'a, const PIX_WIDTH: usize, WX: WrapMode, WY: WrapMode> { /* private fields */ }

Image accessor with tiling: wraps coordinates using WrapMode policies.

Port of C++ image_accessor_wrap<PixFmt, WrapX, WrapY>.

Implementations

impl<'a, const PIX_WIDTH: usize, WX: WrapMode, WY: WrapMode> ImageAccessorWrap<'a, PIX_WIDTH, WX, WY>

pub fn new(rbuf: &'a RowAccessor) -> Self

Trait Implementations

impl<const PIX_WIDTH: usize, WX: WrapMode, WY: WrapMode> ImageSource for ImageAccessorWrap<'_, PIX_WIDTH, WX, WY>

fn span(&mut self, x: i32, y: i32, len: u32) -> &[u8]

Begin reading a span at (x, y) with len pixels. Returns first pixel.

fn next_x(&mut self) -> &[u8]

Advance to the next pixel in the x direction.

fn next_y(&mut self) -> &[u8]

Advance to the next row (y+1), resetting x to the span start.
