To offset an image a certain number of pixels in the X and/or Y direction use this special process. Specify:
Horizontal Offset: (Pixels) Offset in the X axis
Vertical Offset: (Pixels) Offset in the Y axis
Background Color = Background color of the new image. This is an integer value
BackColor = Red + Green*256 + Blue*256*256 (Red, Green and Blue are 8 bits each)
For example, = (R=51, G=193, B = 172) = 51 + 193*256 + 172*256*256 = 11321651
