Enum exr::block::samples::Sample

pub enum Sample {
    F16(f16),
    F32(f32),
    U32(u32),
}

A single red, green, blue, or alpha value.

Variants

F16(f16)

A 16-bit float sample.

F32(f32)

A 32-bit float sample.

U32(u32)

An unsigned integer sample.

Implementations

impl Sample

pub fn f32(f32: f32) -> Self

Create a sample containing a 32-bit float.

pub fn f16(f16: f16) -> Self

Create a sample containing a 16-bit float.

pub fn u32(u32: u32) -> Self

Create a sample containing a 32-bit integer.

pub fn to_f16(self) -> f16

Convert the sample to an f16 value. This has lower precision than f32. Note: An f32 can only represent integers up to 1024 as precise as a u32 could.

pub fn to_f32(self) -> f32

Convert the sample to an f32 value. Note: An f32 can only represent integers up to 8388608 as precise as a u32 could.

pub fn to_u32(self) -> u32

Convert the sample to a u32. Rounds floats to integers the same way that 3.1 as u32 does.

pub fn is_nan(self) -> bool

Is this value not a number?

pub fn is_zero(&self) -> bool

Is this value zero or negative zero?

Trait Implementations

impl Clone for Sample

fn clone(&self) -> Sample
