Struct Tile 

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

An immutable strided view over a region of pixels.

Implementations

impl<'a> Tile<'a>

pub fn new( region: Region, pixel: PixelFormat, stride: usize, data: &'a [u8], ) -> Result<Self>

Wrap data as a tile covering region.

stride is the distance in bytes between the starts of consecutive rows, and must be at least region.width * pixel.bytes_per_pixel().

Errors

Returns PixelsError::InvalidArgument if stride is shorter than one packed row, or if data is too small to cover region at stride.

pub const fn region(&self) -> Region

The region of the image this tile covers.

pub const fn pixel(&self) -> PixelFormat

The pixel format of the samples in this tile.

pub const fn stride(&self) -> usize

Distance in bytes between the starts of consecutive rows.

pub const fn row_bytes(&self) -> usize

Packed length in bytes of one row of this tile.

pub fn row(&self, y: u32) -> Option<&'a [u8]>

The row at image coordinate y, or None if outside the region.

pub fn rows(&self) -> impl Iterator<Item = &'a [u8]> + '_

The tile’s rows, top to bottom.

Trait Implementations

impl<'a> Clone for Tile<'a>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Copy for Tile<'a>

impl<'a> Debug for Tile<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
