Using embedded clipping paths
You can use image-editing applications to embed paths and alpha channels in an image.
If a picture storing this information is imported into QuarkXPress, you can access the path
and channel information using the Clipping tab in the Modify dialog boxon Windows ,
or the Clipping tab of the Measurements paletteon MAC OS X.
TIFFs and PSDs can have embedded paths and alpha channels. EPS, BMP, JPEG, PCX, and
PICT files can only have embedded paths.
Manipulating clipping paths
After you apply a clipping path, choose Item > Edit > Clipping Path to enable clipping
path editing. Then choose one of the following tools: The Select Point tool , the Add
Point tool , the Remove Point tool , and the Convert Point tool . For more
information, see "Tools."
You can also manipulate clipping paths with the controls in the Measurements palette.
To change a point from one type to another, use one of the following three buttons:
•
Symmetrical Point : A symmetrical point connects two curved lines to form a
continuous curve. The result is similar to a smooth point, but the 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.
