SKData Class
Definition
Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
The SKData holds an immutable data buffer.
public class SKData : SkiaSharp.SKObject
- Inheritance
Remarks
Not only is the data immutable, but the actual pointer that is returned by the Data property is guaranteed to always be the same for the life of this instance.
The AsStream() method can be used to return a Stream that wraps this SKData and allows for .NET APIs to scan the contents of the SKData as a stream.
Properties
Data |
Gets a pointer to the data wrapped by this SKData. |
Empty |
Gets a reference to the empty data instance. |
Handle |
Gets or sets the handle to the underlying native object. (Inherited from SKObject) |

Gets or sets a value indicating whether the call the public Dispose() should be no-op. (Inherited from SKNativeObject) |
IsDisposed |
Gets or sets a value indicating whether the object has already been disposed. (Inherited from SKNativeObject) |
IsEmpty |
Gets a value indicating whether or not the data is empty. |
OwnsHandle |
Gets a value indicating whether this object should destroy the underlying native object. (Inherited from SKObject) |
Size |
Gets the size of this data object in bytes. |
Span |
Methods
AsSpan() |
Returns a span that wraps the underlying data. |
AsStream() | |
AsStream(Boolean) | |

Create(IntPtr, Int32, SKDataReleaseDelegate, Object) |
Returns a new SKData instance with reference to the specified data. |
Create(SKStream) |
Returns a new SKData instance with a copy of the data from the stream. |
Create(SKStream, Int32) |
Returns a new SKData instance with a copy of the data from the stream. |
Create(SKStream, Int64) |
Returns a new SKData instance with a copy of the data from the stream. |
Create(SKStream, UInt64) |
Returns a new SKData instance with a copy of the data from the stream. |
Create(Stream) |
Returns a new SKData instance with a copy of the data from the stream. |
Create(Stream, Int32) |
Returns a new SKData instance with a copy of the data from the stream. |
Create(Stream, Int64) |

Create(Stream, UInt64) |
Returns a new SKData instance with a copy of the data from the stream. |
Create(String) |
Returns a new SKData instance with the data from the file. |
Create(UInt64) |

Dispose() |
Releases all resources used by this SKNativeObject. (Inherited from SKNativeObject) |
Dispose(Boolean) |
Releases the resources associated with the data. If this SKData was created with one of the SkiaSharp.SKData.FromMallocMemory(System.IntPtr,System.UInt64) methods, then the operating system's "free" method will be called on the data. |
