Transform Menu
Repeat Last
Applies the most recently used transformation to the current selection. The options window for the transformation, if there is one, is not shown.
Basic
Set Level
Sets the height of the selected squares to a specific value.
Raise By One
Increases the height of the selected squares by one unit (13 metres). There is
no options window for this transform.
Lower By One
Decreases the height of the selected squares by one unit (13 metres). There is
no options window for this transform.
Gradient
Creates a smooth slope over the selected squares. The options window allows you
to specify the height of the slope at the corners of the bounding rectangle of
the selection.
Fill
Selected squares that are less than the specified height are changed to be
that height. Selected squares that are already higher are not affected.
Level Off
Selected squares that are greater than the specified height are changed to be
that height. Selected squares that are already lower are not affected.
Scale
Changes the height of the selected squares by the specified percentage. The
base height is used as a zero reference point for the scaling. For example, if
you wanted to double the size of a mountain, and the base of the mountain was
3 units (39 metres) above sea level, you would enter 200% for the scaling
factor and 3 units as the base height.
Samples
Roughen
Randomly changes the height of the selected squares by either increasing
the height by one, decreasing by one or not changing the height.
