Struct ColorTransform

pub struct ColorTransform { /* private fields */ }

Color transformation from a color encoding to another.

Implementations

impl ColorTransform

pub fn builder() -> ColorTransformBuilder

Creates a new ColorTransform builder.

pub fn new( from: &ColorEncodingWithProfile, to: &ColorEncodingWithProfile, oim: &OpsinInverseMatrix, tone_mapping: &ToneMapping, ) -> Result<Self>

Prepares a color transformation.

Errors

This function will return an error if it cannot prepare such color transformation.

pub fn xyb_to_enum( xyb_rendering_intent: RenderingIntent, encoding: &EnumColourEncoding, oim: &OpsinInverseMatrix, tone_mapping: &ToneMapping, ) -> Result<Self>

Prepares a color transformation from XYB color encoding.

Errors

This function will return an error if it cannot prepare such color transformation.

pub fn is_noop(&self) -> bool

pub fn input_channels(&self) -> usize

pub fn output_channels(&self) -> usize

pub fn run<Cms: ColorManagementSystem + ?Sized>( &self, channels: &mut [&mut [f32]], cms: &Cms, ) -> Result<usize>

Performs the prepared color transformation on the samples.

Returns the number of final channels after transformation.

channels are planar sample data, all having the same length.

Errors

This function will return an error if it encountered ICC to ICC operation and the provided CMS cannot handle it.

pub fn run_with_threads<Cms: ColorManagementSystem + Sync + ?Sized>( &self, channels: &mut [&mut [f32]], cms: &Cms, pool: &JxlThreadPool, ) -> Result<usize>

Performs the prepared color transformation on the samples with the thread pool.

Returns the number of final channels after transformation.

channels are planar sample data, all having the same length.

Errors

This function will return an error if it encountered ICC to ICC operation and the provided CMS cannot handle it.
