Struct ImageAccessorClip 

pub struct ImageAccessorClip<'a, const PIX_WIDTH: usize> { /* private fields */ }

Image accessor with clipping: returns a background color for out-of-bounds pixels.

Port of C++ image_accessor_clip<PixFmt>.

Implementations

impl<'a, const PIX_WIDTH: usize> ImageAccessorClip<'a, PIX_WIDTH>

pub fn new(rbuf: &'a RowAccessor, bk_color: &[u8]) -> Self

pub fn set_background(&mut self, bk_color: &[u8])

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

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

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

Trait Implementations

impl<const PIX_WIDTH: usize> ImageSource for ImageAccessorClip<'_, PIX_WIDTH>

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.
