}

1D LUT. values holds length * 3 interleaved RGB values.

Fields

direction: TransformDirection

The transform direction.

values: Vec<f32>

Interleaved RGB values (length * 3).

input_half_domain: bool

If true, entries are indexed by half-float bit patterns (65536 entries).

output_raw_halfs: bool

If true, values are stored as raw half-float bit patterns when written.

hue_adjust: Lut1DHueAdjust

The hue adjustment applied after the LUT.

interpolation: Interpolation

The interpolation.

file_output_bit_depth: BitDepth

Bit depth used to scale the values when written to a file.

metadata: FormatMetadata

Format metadata.

Implementations

impl Lut1DTransform

pub fn new(length: usize, half_domain: bool) -> Self

Identity LUT of the given length. With half_domain, the length must be 65536 and entries are indexed by half-float bit patterns.

pub fn length(&self) -> usize

Number of entries.

pub fn set_length(&mut self, length: usize)

Resize and reset to identity.

pub fn value(&self, index: usize) -> [f32; 3]

RGB value at index (panics if out of bounds).

pub fn set_value(&mut self, index: usize, r: f32, g: f32, b: f32)

Set the RGB value at index (panics if out of bounds).

Trait Implementations

impl BuildOps for Lut1DTransform

fn build_ops( &self, ops: &mut OpVec, _config: &Config, _context: &Context, dir: TransformDirection, ) -> Result<()>

Append the ops implementing self to ops. dir is the direction requested by the caller; implementations must combine it with the transform’s own direction (self.direction.combine(dir)).

impl Clone for Lut1DTransform

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Lut1DTransform

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

Formats the value using the given formatter.

impl Default for Lut1DTransform

fn default() -> Self

Returns the “default value” for a type.

impl Display for Lut1DTransform

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

Formats the value using the given formatter.

impl From<Lut1DTransform> for Transform

fn from(t: Lut1DTransform) -> Self

Converts to this type from the input type.

impl PartialEq for Lut1DTransform

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

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for Lut1DTransform

impl Validate for Lut1DTransform

fn validate(&self) -> Result<()>

Return an error if the parameters are invalid.
