Implementations

impl Processor

pub fn builder() -> ProcessorBuilder

Creates a new builder-pattern struct instance to construct Processor objects.

This method returns an instance of ProcessorBuilder which can be used to create Processor objects.

pub fn buffer(&self) -> Option<Buffer>

Returns the (cache) buffer the processor is rendering into, another way of getting to the same pixel data is calling gegl_node_blit with flags indicating that we want caching and accept dirty data.

Returns

the Buffer rendered into.

pub fn set_level(&self, level: i32)

pub fn set_rectangle(&self, rectangle: &Rectangle)

Change the rectangle a Processor is working on.

rectangle

the new Rectangle the processor shold work on or NULL to make it work on all data in the buffer.

pub fn set_scale(&self, scale: f64)

pub fn work(&self) -> Option<f64>

Do an iteration of work for the processor.

Returns TRUE if there is more work to be done.

---

GeglProcessor *processor = gegl_node_new_processor (node, &roi); double progress;

while (gegl_processor_work (processor, &progress)) g_warning (“f%% complete”, progress); g_object_unref (processor);

Returns

progress

a location to store the (estimated) percentage complete.

pub fn chunksize(&self) -> i32

pub fn set_node(&self, node: Option<&Node>)

pub fn progress(&self) -> f64

pub fn set_progress(&self, progress: f64)

pub fn connect_node_notify<F: Fn(&Self) + 'static>( &self, f: F ) -> SignalHandlerId

pub fn connect_progress_notify<F: Fn(&Self) + 'static>( &self, f: F ) -> SignalHandlerId

pub fn connect_rectangle_notify<F: Fn(&Self) + 'static>( &self, f: F ) -> SignalHandlerId

Trait Implementations

impl Clone for Processor

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the object. Dropping the object will decrement it again.

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.

impl HasParamSpec for Processor

type ParamSpec = ParamSpecObject

type SetValue = Processor

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str) -> ParamSpecObjectBuilder<'_, Processor>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for Processor

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

Hashes the memory address of this object.

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 Processor

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

Comparison for two GObjects.

Compares the memory addresses of the provided objects.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl ParentClassIs for Processor

type Parent = Object

impl<OT: ObjectType> PartialEq<OT> for Processor

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

Equality for two GObjects.

Two GObjects are equal if their memory addresses are equal.

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

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

impl<OT: ObjectType> PartialOrd<OT> for Processor

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

Partial comparison for two GObjects.

Compares the memory addresses of the provided objects.

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl StaticType for Processor

fn static_type() -> Type

Returns the type identifier of Self.
