Struct exr::meta::attribute::Preview[−][src]

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

impl Preview[src]

pub fn byte_size(&self) -> usize[src]

Number of bytes this would consume in an exr file.

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

Without validation, write this instance to the byte stream.

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

Read the value without validating.

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

Validate this instance.
