Parameters

buffer  Array2DT

An Array2D<T> to be used as the underlying buffer for the returned IReadWriteBitmapData.

pixelWidth  Int32

The width of the bitmap data to create in pixels.

pixelFormatInfo  PixelFormatInfo

A PixelFormatInfo instance that describes the pixel format.

rowGetColor  FuncICustomBitmapDataRowT, Int32, Color32

A delegate that can get the 32-bit color of a pixel in a row of the bitmap data. If pixelFormatInfo represents a wider format it is recommended to use the CreateBitmapDataT(Array2DT, Int32, CustomBitmapDataConfig) overload instead. If , then the returned instance will be write-only (can be cast to IWritableBitmapData).

rowSetColor  ActionICustomBitmapDataRowT, Int32, Color32

A delegate that can set the color of a pixel from a Color32 value in a row of the bitmap data. If pixelFormatInfo represents a wider format it is recommended to use the CreateBitmapDataT(Array2DT, Int32, CustomBitmapDataConfig) overload instead. If , then the returned instance will be read-only (can be cast to IReadableBitmapData).

backColor  Color32  (Optional)

For pixel formats without alpha gradient support specifies the BackColor value of the returned IReadWriteBitmapData instance. It does not affect the actual returned bitmap content. See the Remarks section of the CreateBitmapData(Size, KnownPixelFormat, WorkingColorSpace, Color32, Byte) overload for details. The alpha value (Color32.A field) of the specified background color is ignored. This parameter is optional.
Default value: The default value of the Color32 type, which has the same RGB values as Black.

alphaThreshold  Byte  (Optional)

For pixel formats without alpha gradient support specifies the AlphaThreshold value of the returned IReadWriteBitmapData instance. See the Remarks section of the CreateBitmapData(Size, KnownPixelFormat, WorkingColorSpace, Color32, Byte) overload for details. This parameter is optional.
Default value: 128.

disposeCallback  Action  (Optional)

A delegate to be called when the returned IReadWriteBitmapData is disposed or finalized. This parameter is optional.
Default value: .

Type Parameters

T

The type of the elements in buffer.
