virtual int SetRowColumn( 
   int row,
   int column,
   array<byte>^ buffer,
   int bufferIndex,
   int bufferCount
) 

Parameters

row

The number of the row to update. The first row is 0, and the last row is 1 less than the image height.

column

The column offset within the row to update. The first column offset is 0, and the last column offset is 1 less than the image width.

buffer

Buffer containing the image data.

bufferIndex

0-based index into the buffer. This is the start location of output data.

bufferCount

Number of bytes to copy to the buffer.

Return Value

The data is copied exactly as it is stored in the buffer.

By using this low-level method to update any part of a row, you can write a procedure that updates a single pixel or a rectangular area within the image.
