Struct exr::block::lines::LineIndex

pub struct LineIndex {
    pub layer: usize,
    pub channel: usize,
    pub level: Vec2<usize>,
    pub position: Vec2<usize>,
    pub sample_count: usize,
}

Specifies where a row of pixels lies inside an image. This is a globally unique identifier which includes the layer, channel index, and pixel location.

Fields

layer: usize

Index of the layer.

channel: usize

The channel index of the layer.

level: Vec2<usize>

Index of the mip or rip level in the image.

position: Vec2<usize>

Position of the most left pixel of the row.

sample_count: usize

The width of the line; the number of samples in this row, that is, the number of f16, f32, or u32 values.

Implementations

impl LineIndex

pub fn lines_in_block( block: BlockIndex, channels: &ChannelList, ) -> impl Iterator<Item = (Range<usize>, LineIndex)>

Iterates the lines of this block index in interleaved fashion: For each line in this block, this iterator steps once through each channel. This is how lines are stored in a pixel data block.

Does not check whether self.layer_index, self.level, self.size and self.position are valid indices.__

Trait Implementations

impl Clone for LineIndex

fn clone(&self) -> LineIndex

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LineIndex

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

Formats the value using the given formatter.

impl Hash for LineIndex

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 for LineIndex

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

Tests for self and other values to be equal, and is used by ==.

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

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