Struct exr::meta::attribute::Preview

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

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

impl Preview

pub fn byte_size(&self) -> usize

Number of bytes this would consume in an exr file.

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

Without validation, write this instance to the byte stream.

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

Read the value without validating.

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

Validate this instance.

Trait Implementations

impl Clone for Preview

fn clone(&self) -> Preview

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Preview

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

Formats the value using the given formatter.

impl PartialEq for Preview

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Eq for Preview
