Struct exr::meta::attribute::Preview

source · [−]

pub struct Preview {
    pub size: Vec2<usize>,
    pub pixel_data: Vec<i8>,
}

Expand description

A small rgba image of i8 values that approximates the real exr image.

Fields

size: Vec2<usize>

The dimensions of the preview image.

pixel_data: Vec<i8>

An array with a length of 4 × width × height. The pixels are stored in LineOrder::Increasing. Each pixel consists of the four u8 values red, green, blue, alpha.

Implementations

source

impl Preview

source

pub fn byte_size(&self) -> usize
