Declares additional transformation options

Fields

rendering_intent: RenderingIntent

allow_use_cicp_transfer: bool

If set it will try to use Transfer Characteristics from CICP on transform. This might be more precise and faster.

prefer_fixed_point: bool

Prefers fixed point where implemented as default. Most of the applications actually do not need floating point.

Do not change it if you’re not sure that extreme precision is required, in most cases it is a simple way to spend energy to warming up environment a little.

Q2.13 for RGB->XYZ->RGB is used. LUT interpolation use Q0.15.

interpolation_method: InterpolationMethod

Interpolation method for 3D LUT

This parameter has no effect on LAB/XYZ interpolation and scene linear RGB.

Technically, it should be assumed to perform cube dividing interpolation:

• Source colorspace is gamma-encoded (discards scene linear RGB and XYZ).
• Colorspace is uniform.
• Colorspace has linear scaling (discards LAB).
• Interpolation doesn’t shift hues (discards LAB).

For LAB, XYZ and scene linear RGB trilinear/quadlinear always in force.

barycentric_weight_scale: BarycentricWeightScale

Barycentric weights scale.

This value controls LUT weights precision.

allow_extended_range_rgb_xyz: bool

For floating points transform, it will try to detect gamma function on Matrix Shaper profiles. If gamma function is found, then it will be used instead of LUT table. This allows to work with excellent precision with extended range, at a cost of execution time.

Trait Implementations

impl Clone for TransformOptions

fn clone(&self) -> TransformOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TransformOptions

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

Formats the value using the given formatter.

impl Default for TransformOptions

fn default() -> Self

Returns the “default value” for a type.

impl Hash for TransformOptions

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for TransformOptions

fn cmp(&self, other: &TransformOptions) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for TransformOptions

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for TransformOptions

fn partial_cmp(&self, other: &TransformOptions) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
