where T: Read + Seek,

pub fn from_data(data: impl Into<RCHandle<SkData>>) -> Option<Codec<'static>>

pub fn from_data_with_decoders( data: impl Into<RCHandle<SkData>>, decoders: &[Handle<SkCodecs_Decoder>], ) -> Option<Codec<'static>>

pub fn get_pixels_with_options( &mut self, info: &Handle<SkImageInfo>, pixels: &mut [u8], row_bytes: usize, options: Option<&Options>, ) -> SkCodec_Result

pub unsafe fn get_pixels( &mut self, info: &Handle<SkImageInfo>, pixels: *mut c_void, row_bytes: usize, ) -> SkCodec_Result

👎Deprecated since 0.33.1: Use the safe variant get_pixels_with_options().

Blanket Implementations§

source§

impl<T> Any for T
where T: 'static + ?Sized,

source§

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more
source§

impl<T> Borrow<T> for T
where T: ?Sized,

source§

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more
source§

impl<T> BorrowMut<T> for T
where T: ?Sized,

source§

fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. Read more
§

impl<T> Downcast for T
where T: Any,

§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.
§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.
§

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.
§

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.
