 function Leadtools.RasterImage.SetPixelData(Int32,Int32,IntPtr,Int32)(  
   row , 
   column , 
   data , 
   dataSize  
) 
public: 
void SetPixelData(  
   int row, 
   int column, 
   IntPtr data, 
   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.

Remarks

The image memory must be locked when you use this method. Normally, you can call Access to lock the memory before starting an operation that uses this method. Then call Release when the operation is finished.

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.
