Struct exr::meta::attribute::TileDescription

pub struct TileDescription {
    pub tile_size: Vec2<usize>,
    pub level_mode: LevelMode,
    pub rounding_mode: RoundingMode,
}

Describes how the layer is divided into tiles. Specifies the size of each tile in the image and whether this image contains multiple resolution levels.

Fields

tile_size: Vec2<usize>

The size of each tile. Stays the same number of pixels across all levels.

level_mode: LevelMode

Whether to also store smaller versions of the image.

rounding_mode: RoundingMode

Whether to round up or down when calculating Mip/Rip levels.

Implementations

impl TileDescription

pub fn byte_size() -> usize

Number of bytes this would consume in an exr file.

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

Without validation, write this instance to the byte stream.

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

Read the value without validating.

pub fn validate(&self) -> UnitResult

Validate this instance.

Trait Implementations

impl Clone for TileDescription

fn clone(&self) -> TileDescription

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TileDescription

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

Formats the value using the given formatter.

impl Hash for TileDescription

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<TileDescription> for TileDescription

fn eq(&self, other: &TileDescription) -> 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.
