Scaling an Object
Pressing Mouse-Button-1 in any of the points surrounding the selected
object, invokes the commands to scale the object.
The method in which rectangles and polygon type objects are scaled is the
same. Circles are slightly different.
Scaling Rectangles and Polygons
- Points 1,3,6 and 8
- Allow scaling in both the x- and y- planes. The anchor position for
the scaling calculation is the diagonally opposite corner.
- Points 2 and 7
- Allow scaling in the y-plane only. The anchor position for the
scaling calculation is the y-coordinate of the opposite side of the
bounding-box.
- Points 4 and 5
- Allow scaling in the x-plane only. The anchor position for the
scaling calculation is the x-coordinate of the opposite side of the
bounding-box.
Scaling Circles

- Points 1,3,6 and 8
- These carry out no function on circles. This is in order to preserve
the aspect-ratio.
- Point 2
- If this point is selected, point 8 is the anchor point for the
scaling function. The circle is scaled in accordance with movements
in the y-direction.
- Point 4
- As with Point 2, but with scaling in accordance with movements
in the x-direction.
- Point 5
- If this point is selected, point 1 is the anchor point for the
scaling function. The circle is scaled in accordance with movements
in the x-direction.
- Point 7
- As with Point 5, but with scaling in accordance with movements
in the y-direction.
