Struct Processor 

pub struct Processor { /* private fields */ }

A color processor.

Implementations

impl Processor

pub fn from_ops(ops: OpVec) -> Self

Build a processor from an op list.

pub fn from_transform( config: &Config, context: &Context, transform: &Transform, dir: TransformDirection, ) -> Result<Self>

Build a processor for transform in dir, using config and context to resolve color spaces, looks and files.

pub fn ops(&self) -> &[OpRc]

The (unoptimized) ops.

pub fn is_no_op(&self) -> bool

True if the processor does nothing.

pub fn has_channel_crosstalk(&self) -> bool

True if an output channel depends on other input channels.

pub fn cache_id(&self) -> String

Cache identifier: a hash of the op cache ids. As in OCIO, it is computed even for a no-op processor, so that different lists of identity ops do not share the same id (the config processor cache reuses a processor having the same id).

pub fn processor_metadata(&self) -> &ProcessorMetadata

Files and looks used to build the processor.

pub fn format_metadata(&self) -> &FormatMetadata

Metadata of the group transform the processor was built from.

pub fn num_transforms(&self) -> usize

Number of transforms of the source group transform (0 if not a group).

pub fn transform_format_metadata(&self, index: usize) -> Option<&FormatMetadata>

Metadata of the transform at index of the source group transform.

pub fn create_group_transform(&self) -> GroupTransform

Convert the ops back to transforms.

pub fn is_dynamic(&self) -> bool

True if any op has a dynamic property.

pub fn has_dynamic_property(&self, ty: DynamicPropertyType) -> bool

True if an op has a dynamic property of the given type.

pub fn dynamic_property( &self, ty: DynamicPropertyType, ) -> Option<DynamicProperty>

The dynamic property of the given type (shared by all ops using it).

pub fn optimized(&self, flags: OptimizationFlags) -> Processor

Processor with optimized ops.

pub fn default_cpu_processor(&self) -> CpuProcessor

CPU processor with the default optimization.

pub fn optimized_cpu_processor(&self, flags: OptimizationFlags) -> CpuProcessor

CPU processor with the given optimization.

pub fn optimized_cpu_processor_with_bit_depths( &self, input: BitDepth, output: BitDepth, flags: OptimizationFlags, ) -> CpuProcessor

CPU processor with bit depths. Images are converted according to their own bit depth in apply; when they have the processor bit depths, the first / last 1D LUTs are rendered as OCIO does for these bit depths (look-up of the input code values, rounding of the scaled output).

impl Processor

pub fn default_gpu_processor(&self) -> Result<Arc<GpuProcessor>>

GPU processor with the default optimization.

pub fn optimized_gpu_processor( &self, flags: OptimizationFlags, ) -> Result<Arc<GpuProcessor>>

GPU processor with the given optimization (the processors are cached by optimization flags).

pub fn optimized_legacy_gpu_processor( &self, flags: OptimizationFlags, edgelen: u32, ) -> Result<Arc<GpuProcessor>>

Legacy GPU processor (OCIO v1 approach): the ops not supported by the legacy shaders (the 1D and 3D LUTs and the ops in between) are baked into a single 3D LUT of edge length edgelen.

Trait Implementations

impl Clone for Processor

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 Processor

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

Formats the value using the given formatter.
