Struct exr::block::chunk::TileCoordinates

pub struct TileCoordinates {
    pub tile_index: Vec2<usize>,
    pub level_index: Vec2<usize>,
}

Indicates the position and resolution level of a TileBlock or DeepTileBlock.

Fields

tile_index: Vec2<usize>

Index of the tile, not pixel position.

level_index: Vec2<usize>

Index of the Mip/Rip level.

Implementations

impl TileCoordinates

pub fn write<W: Write>(&self, write: &mut W) -> UnitResult

Without validation, write this instance to the byte stream.

pub fn read(read: &mut impl Read) -> Result<Self>

Read the value without validating.

pub fn to_data_indices( &self, tile_size: Vec2<usize>, max: Vec2<usize> ) -> Result<IntegerBounds>

The indices which can be used to index into the arrays of a data window. These coordinates are only valid inside the corresponding one header. Will start at 0 and always be positive.

pub fn to_absolute_indices( &self, tile_size: Vec2<usize>, data_window: IntegerBounds ) -> Result<IntegerBounds>

Absolute coordinates inside the global 2D space of a file, may be negative.

pub fn is_largest_resolution_level(&self) -> bool

Returns if this is the original resolution or a smaller copy.

Trait Implementations

impl Clone for TileCoordinates

fn clone(&self) -> TileCoordinates

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TileCoordinates

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

Formats the value using the given formatter.

impl Hash for TileCoordinates

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<TileCoordinates> for TileCoordinates

fn eq(&self, other: &TileCoordinates) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
