Image Rotation, Perspective and Key Frame Dialog Box

Rotation of the Camera Window is controlled by moving the cursor over the small circle located in the upper left hand corner of the Camera Window, holding down the left mouse button and moving the mouse to cause rotation. The cursor will change to a small curved line with arrows on each end to indicate that the Camera Window may be rotated. Accurate rotation is difficult using the cursor method. It is recommended for accurate rotations and for rotations of greater then 360 degrees that the second Camera Control method be used. This is the Set Key Frame Options dialog box that appears when the right mouse button is pressed while the cursor is over the Camera Window. The section about Key frames will make the title of the dialog box clear.

Figure 4 Rotation

The second method for controlling the Camera Window is by through the Set KeyFrames Options dialog box which is brought up by right clicking anywhere in the Camera Window.

Figure 4 shows the KeyFrame Options Dialog Box. The Horizontal Position (X) , Vertical Position (Y), and Width of the Camera Window are shown here as pixel values. These values may be changed by highlighting them with the mouse by holding the left key down while moving over the field and then entering the desired values.

The Rotation field controls the angle the Camera Window is to be rotated to. 360 represents a complete rotation for more than a full rotation use values larger than 360 for example setting the Rotation to 720 will cause two ration between the Key Frames.

The third way to control the position of the Camera windows is to use the Right and Left Arrow keys on the keyboard. Each depression of the key causes the Camera Window to move a single pixel in the indicated direction.

Creating Perspective Effects

The Perspective tool is used as an extension of the Camera Window control.  Rotation of the Camera Window is controlled by moving the cursor over the small circle located in the upper left hand corner of the Camera Window, holding down the left mouse button and moving the mouse to cause rotation. The cursor will change to a small curved line with arrows on each end to indicate that the Camera Window may be rotated.  See the Rotation Reference page. 

Once you have the rotate icon hold the Control key down and the Perspective Cursor will appear.  Now moving the cursor forward and backward will change the shape of the square to a trapezoid representing perspective.  The short side of the trapezoid representing the tilt of the perspective toward the image.
