Struct exr::meta::attributes::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.

Methods

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) -> PassiveResult

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) -> PassiveResult

Validate this instance.
