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 Style > 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 hard 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.
