BitmapDataExtensionsClone(IReadableBitmapData, KnownPixelFormat, Palette) Method
Gets the clone of the specified source with identical size and the specified pixelFormat and palette.

static member Clone :
source : IReadableBitmapData *
pixelFormat : KnownPixelFormat *
palette : Palette -> IReadWriteBitmapData
- source IReadableBitmapData
- An IReadableBitmapData instance to be cloned.
- pixelFormat KnownPixelFormat
- The desired pixel format of the result.
- palette Palette
- If pixelFormat is an indexed format, then specifies the desired Palette of the returned IReadWriteBitmapData instance.
It determines also the BackColor and AlphaThreshold properties of the result.
If , then the target palette is taken from source if it also has a palette of no more entries than the target indexed format can have;
otherwise, a default palette will be used based on pixelFormat.
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. Use the
BeginClone(IReadableBitmapData, KnownPixelFormat, Palette, NullableRectangle, AsyncConfig)
or
CloneAsync(IReadableBitmapData, KnownPixelFormat, Palette, NullableRectangle, TaskConfig) (in .NET Framework 4.0 and above) methods for asynchronous call and to adjust parallelization, set up cancellation and for reporting progress.
This overload automatically quantizes colors if pixelFormat represents a narrower set of colors than source PixelFormat.
To use a custom quantizer use the overloads with an IQuantizer parameter.
Color depth of wide-color formats (Format16bppGrayScale, Format48bppRgb, Format64bppArgb, Format64bppPArgb)
can be preserved only between the same pixel formats. If they are different, then colors might be quantized to 32bpp ones during the operation.
See the
Examples section of the
ConvertPixelFormat(Image, PixelFormat, Color[], Color, byte) extension method
for some examples. The
ConvertPixelFormat extensions work the same way
for
Images
as the
Clone extensions for
IReadableBitmapData instances.
