10.0

file contains more than one embedded alpha channel. Note that using a clipping path
around an alpha channel will create a hard edge rather than a blended effect. If you want
a semi-opaque blend, use an alpha mask. (See "Working with alpha masks.")
• Choose Non-White Areas to create a clipping path based on the picture's subject.
Depending on the image and the value in the Threshold field, the clipping path will
outline a non-white figure within a larger white or near-white image (or vice versa). The
Non-White Areas option works best when the unwanted parts of the image are much
lighter than the subject itself (or vice versa).
• Choose Picture Bounds to clip a picture around the rectangular "canvas area" of the
imported picture file. This includes any white background areas saved with the original
picture file. Enter values in the Top, Left, Bottom, and Right fields to determine the outset
of the clipping path from the picture's boundaries. Positive values increase the outset, and
negative values decrease the outset.
Clipping tab of the Modify dialog box
The green path in the Preview area corresponds to the clipping path, and the blue outline
corresponds to the picture box.
