Define here the maximum and step parameters
controlling the ruler (in the tools menu).
Rotate
Max sets the range of angle values accepted by the ruler,
to rotate objects. Clicking on the ruler extreme left, the
object is rotated by
-Max. Clicking on the ruler
extreme right, the object is rotated by
Max.
Max must be positive.
The rotation angle applied to the object, when clicking on the
ruler, increases from the extreme left to the extreme right
(from
-Max to
+Max), in a step by step way.
The width of each step, starting from the center to the extremes,
is defined by
Step.
For example, when
Step is set to
Max,
only two angles are recognized:
-Max on the left
(negative) side and
+Max on the right (positive)
side of the ruler. When
Step is 0, the angle
changes continuously from one extreme to the other.
Step cannot exceed
Max, otherwise the extreme
values would never be reached (the central value is always 0).
Move
Max sets the range of length values accepted by the ruler,
to move objects. Clicking on the ruler extreme left, the
object is moved by
-Max. Clicking on the ruler
extreme right, the object is moved by
Max.
Max must be positive.
The translation length applied to the object, when clicking on
the ruler, increases from the extreme left to the extreme right
(from
-Max to
+Max), in a step by step way.
The width of each step, starting from the center to the extremes,
is defined by
Step.
For example, when
Step is set to
Max,
only two lengths are recognized:
-Max on the left
(negative) side and
+Max on the right (positive)
side of the ruler. When
Step is 0, the length
changes continuously from one extreme to the other.
Step cannot exceed
Max, otherwise the extreme
values would never be reached (the central value is always 0).
Scale
Max sets the range of factor values accepted by the ruler,
to scale objects. Clicking on the ruler extreme left, the object
is scaled by
1 / Max. Clicking on the ruler extreme right,
the object is scaled by
Max.
Max must be larger than 1.
For example, when
Step is set to
Max - 1,
only two factors are recognized:
1 / Max on the left
side and
Max on the right side of the ruler. When
Step is 0, the factor changes continuously
from one extreme to the other.
Step cannot exceed
Max - 1, otherwise the extreme
values would never be reached (the central value is always 1).
