- Ruler

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).
