-> IReadWriteBitmapData 

Parameters

buffer  IntPtr

The memory address to be used as the underlying buffer for the returned IReadWriteBitmapData. Make sure there is enough allocated memory for the specified size, stride and pixelFormatInfo; otherwise, accessing pixels may corrupt memory or throw an AccessViolationException. If it points to managed memory make sure it is pinned until the returned bitmap data is disposed.

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. It can be negative for bottom-up layout (ie. when buffer points to the first pixel of the bottom row).

pixelFormatInfo  PixelFormatInfo

A PixelFormatInfo instance that describes the pixel format.

rowGetColorIndex  FuncICustomBitmapDataRow, Int32, Int32

A delegate that can get the color index of a pixel in a row of the bitmap data. If , then the returned instance will be write-only (can be cast to IWritableBitmapData).

rowSetColorIndex  ActionICustomBitmapDataRow, Int32, Int32

A delegate that can set the color index of a pixel in a row of the bitmap data. If , then the returned instance will be read-only (can be cast to IReadableBitmapData).

palette  Palette  (Optional)

Specifies the desired Palette of the returned IReadWriteBitmapData instance. It determines also the BackColor and AlphaThreshold properties of the result. This parameter is optional.
Default value: .

trySetPaletteCallback  FuncPalette, Boolean  (Optional)

A delegate to be called when the palette is attempted to be replaced by the TrySetPalette method. If buffer belongs to some custom bitmap implementation, it can be used to update its original palette. This parameter is optional.
Default value: .

disposeCallback  Action  (Optional)

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

Return Value
