Struct exr::image::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>

Pixel position of the bottom left corner of the block.

pixel_size: Vec2<usize>

Pixel size of the block.

level: Vec2<usize>

Index of the mip or rip level in the image.

Methods

impl BlockIndex

#[must_use] pub fn line_indices(
    &self,
    header: &Header
) -> 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
