row
The zero-based row number of the pixel.
column
The zero-based column number of the pixel.
data
Pointer to an unmanaged memory buffer that contains the pixel data to set. This buffer should contain ((BitsPerPixel + 7) / 8) bytes.
dataSize
Size of the data unmanaged memory buffer.
Changes the data of the specified pixel by copying from an unmanaged memory buffer.

   int dataSize
) 

Parameters

row
The zero-based row number of the pixel.
column
The zero-based column number of the pixel.
data
Pointer to an unmanaged memory buffer that contains the pixel data to set. This buffer should contain ((BitsPerPixel + 7) / 8) bytes.
dataSize
Size of the data unmanaged memory buffer.

Example

For an example, refer to GetPixelData.

Remarks

No transformations are performed on the pixel data.

This method should be called only for 8, 16, 24, 32, 48 and 64-bit images.

Use the GetPixelData method to get data of a specified pixel.
