56 Manipulating Objects
Dragging from an edge handle resizes in one dimension, by moving that
edge. Dragging from a corner handle resizes in two dimensions, by
moving two edges.
To resize freely:
Drag from a corner (or line end) handle.
To constrain an object's dimensions when resizing:
Hold the Shift key down and drag from a corner (or line end)
handle.
For shapes, this has the effect of keeping a square as a square, a circle as
a circle, etc.
For pictures, dimensions are constrained on dragging a corner
handle. Use Shift-drag to resize a picture freely.
To resize about the object centre instead, press the Ctrl key as you
drag edge or corner handles; Ctrl+Shift+drag to for a constrained
resize about the object centre.
You can also make fine resizing adjustments from the Transform
tab.
