Inset Frame Shrinks the resulting clipping path relative to the clipping path defined by the Threshold and Tolerance
values. Unlike Threshold and Tolerance, the Inset Frame value does not take lightness values into account; instead,
it uniformly shrinks the shape of the clipping path. Adjusting the Inset Frame value slightly may help hide stray pixels
that could not be eliminated by using the Threshold and Tolerance values. Enter a negative value to make the
resulting clipping path larger than the clipping path defined by the Threshold and Tolerance values.
Inset frame at -0p1 (left) and 0p3 (right)
Invert Switches the visible and hidden areas, by starting the clipping path with the darkest tones.
Include Inside Edges Makes areas transparent if they exist inside the original clipping path, and if their lightness
values are within the Threshold and Tolerance ranges. By default, the Clipping Path command makes only the outer
areas transparent, so use Include Inside Edges to correctly represent “holes” in a graphic. This option works best
when the brightness levels of areas you want to make transparent don’t match any areas that must be visible. For
example, if you choose Include Inside Edges for a graphic of silver eyeglasses, and the lenses become transparent,
very light areas of the eyeglass frame may also become transparent. If areas become transparent when that wasn’t
your intent, try adjusting the Threshold, Tolerance, and Inset Frame values.
Restrict to Frame Creates a clipping path that stops at the visible edge of the graphic. This can result in a simpler path
when you use the graphic’s frame to crop the graphic.
Use High Resolution Image Calculates transparent areas using the actual file, for maximum precision. Deselect this
option to calculate transparency based on the screen display resolution, which is faster but less precise. This option
isn’t available if you chose Alpha Channel, because InDesign always uses an alpha channel at its actual resolution.
