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.
