SKFrontBufferedManagedStream Class

Definition

A read-only stream that buffers the specified first chunk of bytes.

public class SKFrontBufferedManagedStream : SkiaSharp.SKAbstractManagedStream
Inheritance

Remarks

This is useful for decoding images using streams that are not seekable, since SKCodec needs to read the first few bytes to determine the codec to use.

Constructors

SKFrontBufferedManagedStream(SKStream, Int32)

Creates a new instance of SKFrontBufferedStream that wraps the specified stream.

SKFrontBufferedManagedStream(SKStream, Int32, Boolean)

Creates a new instance of SKFrontBufferedStream that wraps the specified stream.

SKFrontBufferedManagedStream(Stream, Int32)

Creates a new instance of SKFrontBufferedStream that wraps the specified stream.

SKFrontBufferedManagedStream(Stream, Int32, Boolean)

Creates a new instance of SKFrontBufferedStream that wraps the specified stream.

Properties

Handle

Gets or sets the handle to the underlying native object.

(Inherited from SKObject)
HasLength

Gets a value indicating whether this stream can report it's total length.

(Inherited from SKStream)
HasPosition

Gets a value indicating whether this stream can report it's current position.

(Inherited from SKStream)
IgnorePublicDispose

Gets or sets a value indicating whether the call the public Dispose() should be no-op.

(Inherited from SKNativeObject)
IsAtEnd

Gets a value indicating whether all the bytes in the stream have been read.

(Inherited from SKStream)
IsDisposed

Gets or sets a value indicating whether the object has already been disposed.

(Inherited from SKNativeObject)
Length

Gets the total length of the stream. If this is not supported, the length will be reported as 0.

(Inherited from SKStream)
OwnsHandle

Gets a value indicating whether this object should destroy the underlying native object.

(Inherited from SKObject)
Position

Gets the current position in the stream. If this is not supported, the position will be reported as 0.
