BitmapDataExtensionsClone(IReadableBitmapData, KnownPixelFormat, IDitherer) Method
Gets the clone of the specified source with identical size and the specified pixelFormat, using an optional ditherer.

static member Clone :
source : IReadableBitmapData *
pixelFormat : KnownPixelFormat *
ditherer : IDitherer -> IReadWriteBitmapData
- source IReadableBitmapData
- An IReadableBitmapData instance to be cloned.
- pixelFormat KnownPixelFormat
- The desired pixel format of the result.
- ditherer IDitherer
- The ditherer to be used. Might be ignored if pixelFormat represents an at least 24 bits-per-pixel size.
IReadWriteBitmapDataAn
IReadWriteBitmapData instance that represents the clone of the specified
source.In Visual Basic and C#, you can call this method as an instance method on any object of type
IReadableBitmapData. When you use instance method syntax to call this method, omit the first parameter. For more information, see
Extension Methods (Visual Basic) or
Extension Methods (C# Programming Guide).
This method adjusts the degree of parallelization automatically, blocks the caller, and does not support cancellation or reporting progress. You can use
the
Clone(IReadableBitmapData, KnownPixelFormat, IQuantizer, IDitherer, ParallelConfig) overload to configure these, while still executing the method synchronously. Alternatively, use
the
BeginClone(IReadableBitmapData, KnownPixelFormat, IQuantizer, IDitherer, NullableRectangle, AsyncConfig) or
CloneAsync(IReadableBitmapData, KnownPixelFormat, IQuantizer, IDitherer, NullableRectangle, TaskConfig)
(in .NET Framework 4.0 and above) methods to perform the operation asynchronously.
If pixelFormat can represent a narrower set of colors, then the result will be automatically quantized to its color space.
To use dithering a ditherer must be explicitly specified.
Color depth can be preserved if the target format can represent the colors of the source format without losing information.
See the
Examples section of the
ConvertPixelFormat(Image, PixelFormat, IQuantizer?, IDitherer?)extension method
for some examples. The
ConvertPixelFormat extensions work the same way
for
Images
as the
Clone extensions for
IReadableBitmapData instances.
