Changes the color value of the specified pixel.
Public Sub SetPixel( _
ByVal row As Integer, _
ByVal column As Integer, _
ByVal color As RasterColor _
The zero-based row number of the pixel.
The zero-based column number of the pixel.
The color to assign to the pixel. If the image has 32 or 64-bits per pixel, the alpha value of this parameter is used in the pixel data.
This method uses image coordinates to specify the pixel. Therefore, you must account for the view perspective of the image. If you specify a pixel that is outside the image or outside the region (if the image has one), this method throws an exception.
Use the GetPixel method to get the color value of a certain pixel.
For 32 and 64-bit images, an alpha value is also available in the image. This method will use the alpha value in color (A). For 32-bit images, this will be the exact byte value of the alpha for the pixel. For 64-bit images, the alpha is 16-bit and since RasterColor.A is an 8-bit value, the alpha is normalized from its 16-bit value to 8-bit. For other bits/pixel values, the method is identical to returned from SetPixelColor.
This method supports unsigned data images, but not signed ones.
The SetPixel function can use the Extended Grayscale mask. For more information, refer to Grayscale Images
