curve handles always rest on a straight line through the point and are always
equidistant from the point.
Smooth Point : A smooth point connects two curved lines to form a ●
continuous curve. The curve handles always rest on a straight line through
the point, but they can be distanced independently.
Corner Point : A corner point connects two straight lines, a straight line ●
and a curved line, or two noncontinuous curved lines. With curved lines, the
corner point’s curve handles can be manipulated independently, usually to
form a sharp transition between the two segments.
To change the character of a line segment, use one of the following buttons:
Straight Segment : Makes the active segment straight. ●
Curved Segment : Makes the active segment curved. ●
You can also change point and segment types with the Item > 
Point/Segment Type submenu.
Creating special effects with clipping paths
Various options in the Clipping tab let you invert a clipping path or specify
whether a picture is clipped using outside edges only, or whether the picture is
contained within its box. You can create special effects such as making visible
regions transparent and transparent regions visible, allowing holes within a
path, cropping the picture to the edges of the picture box, or removing portions
of the clipping path that fall outside the box borders.
Working with alpha masks
Unlike clipping paths, which produce a smooth edge primarily used for
separating a foreground image from a background image, alpha masks can
include transparency information to subtly blend a foreground image into a new
background. To work with alpha masks in QuarkXPress, you must first create an
alpha mask in an image-editing application such as Adobe Photoshop. You can
then use the alpha mask in QuarkXPress.
