This dialog is used to show and set the values of position, size, rotation and other parameters of the selected object. Although you can use mouse-dragging to change the position, size and rotation, it allows you to do in a precise way.

Position
This determines the position of the object relative to the top-left of the slide.

Size
It gives the current dimension of the object in local unit.

Original size
It shows the original width and height of the object in local. This is only for images. If it is valid, you can click Reset button to reset current size of the object to the original one.

Rotation
It determines the rotation angle of the object in degrees.

Lock aspect ratio
It determines whether the aspect ratio of the object is locked. If this option is checked, the aspect ratio will be kept when you resize the object using corner-dragging handles. In addition, you can keep its aspect ratio when you hold SHIFT key during resizing the object even if this option is not checked. However, if you use middle-dragging handles to resize the object, this option does not take effect.
