Struct exr::block::lines::LineIndex[−][src]

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

Expand description

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.__
