Struct exr::block::BlockIndex

pub struct BlockIndex {
    pub layer: usize,
    pub pixel_position: Vec2<usize>,
    pub pixel_size: Vec2<usize>,
    pub level: Vec2<usize>,
}

Specifies where a block of pixel data should be placed in the actual image. This is a globally unique identifier which includes the layer, level index, and pixel location.

Fields

layer: usize

Index of the layer.

pixel_position: Vec2<usize>

Index of the top left pixel from the block within the data window.

pixel_size: Vec2<usize>

Number of pixels in this block, extending to the right and downwards. Stays the same across all resolution levels.

level: Vec2<usize>

Index of the mip or rip level in the image.

Trait Implementations

impl Clone for BlockIndex

fn clone(&self) -> BlockIndex

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BlockIndex

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

Formats the value using the given formatter.

impl Hash for BlockIndex

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<BlockIndex> for BlockIndex

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