| Method | Defines how the raster image is to be adjusted. For each
option, the adjustment is made by defining points on the image, followed by
monument points in the design file. The number of points required varies with
the option used.
- Align (Move, Scale)
— Two points (only) are required and scaling is uniform along
the x- and y-axes.
- Similitude (Move, Scale, Rotate)
— Requires a minimum of two points. Where more than two points
are entered, a best fit is produced from the points. If more than two points
are entered, then the source and destination points may not line up.
- Affine (Move, Scale, Rotate, Skew)
— Requires a minimum of three points and then produces a
best fit. If more than three points are entered, the source and destination
points may not line up.
- Clear Last Point
— Clears the last data point placed. Successive clicking
of the Clear Last Point button clears previous points in the reverse order
to that in which they were placed. That is, the last point placed is the first
one cleared. This lets you delete incorrectly placed points without losing
previous correct points.
