There are 62 horizontal and 32 vertical control points used to define a 62 × 32 map on the input image. Users can choose to define all 62 horizontal points and 32 vertical points for a custom map of source points. Users can also choose to define a number of horizontal points and vertical points in the ranges 2 to 62 and 2 to 32, respectively. In the latter case, all points remain equidistant. For unequal distribution, the former mode must be used.
The total number of points in the user-defined table cannot exceed the number of points in the control point map. A 62 × 32 control point map is most optimal and provides 1984 points. Because the warp table represents the whole output rectangle, the table must have at least 2 rows and 2 columns. The points in the warp table must monotonically increase in the left-to-right and top-to-bottom directions (that is, points cannot crisscross each other). If any of these conditions is violated, the command will return failure.
