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

Number of bytes this would consume in an exr file.

source

pub fn write<W: Write>(&self, write: &mut W) -> UnitResult

Without validation, write this instance to the byte stream.

source

pub fn read<R: Read>(read: &mut R) -> Result<Self>

Read the value without validating.

source

pub fn validate(&self, strict: bool) -> UnitResult

Validate this instance.
