(Offset correction value) = ｛ （Maximum number of interpolatable pixels） － （Sampling cycle after dropping
the fractional portion）×GX｝÷ 2
Example 2 Sampling points
First point:
Second point:
Third point:
254th point:
255th point:
* Pixels 32386 to 32512 are not used.
This produces a slightly off-center scaled-up image shifted to the left.
To realize more natural-looking scaling up, the correction function is utilized.
Example of simple offset correction (using Example 2 described earlier)
Since the offset value in the X direction must be an integer, it is set to 63 (oct) 3F (hex).
Likewise, the offset value in the Y direction is set to 63 (oct)
[Offset correction example]
pixel points are evened out from the center.
generable sampling point.

The offset correction function adds an offset to the first sampling point so that unused
Move the first sampling point to move all the sampling points to the center.
Offset half of the difference between the last sampling point (255th point) and the last
