BitmapDataFactoryCreateBitmapDataT(ArraySectionT, Size, Int32, PixelFormatInfo, FuncICustomBitmapDataRowT, Int32, Color32, ActionICustomBitmapDataRowT, Int32, Color32, Color32, Byte, Action) Method

Creates an IReadWriteBitmapData instance with a custom non-indexed pixel format wrapping the specified buffer and using the specified parameters.
See the Remarks section of the CreateBitmapDataT(T, Size, Int32, PixelFormatInfo, FuncICustomBitmapDataRowT, Int32, Color32, ActionICustomBitmapDataRowT, Int32, Color32, Color32, Byte, Action) overload for details.

Parameters

buffer ArraySectionT: An ArraySection<T> to be used as the underlying buffer for the returned IReadWriteBitmapData. It can be larger than it is required for the specified parameters.
size Size: The size of the bitmap data to create in pixels.
stride Int32: The size of a row in bytes. It allows to have some padding at the end of each row.
pixelFormatInfo PixelFormatInfo: A PixelFormatInfo instance that describes the pixel format.
rowGetColor FuncICustomBitmapDataRowT, Int32, Color32: A delegate that can get the color of a pixel in a row of the bitmap data.
rowSetColor ActionICustomBitmapDataRowT, Int32, Color32: A delegate that can set the color of a pixel in a row of the bitmap data.
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.

Return Value

IReadWriteBitmapData
An IReadWriteBitmapData instance wrapping the specified buffer and using the provided parameters.

Exceptions

ArgumentNullException	buffer is Null -or- rowGetColor or rowSetColor is .
ArgumentOutOfRangeException	size has a zero or negative width or height -or- stride is too small for the specified width and pixelFormatInfo.
ArgumentException	buffer is too small for the specified size, pixelFormatInfo and stride -or- stride is not a multiple of the size of T -or- pixelFormatInfo is indexed or its BitsPerPixel is 0.
