Runaround tab of Picture dialog box, showing runaround preview
(Mac OS X only): To apply text runaround to a picture box in front of a text box, select
the picture box, use the Runaround tab of the Measurements palette.
Fine-tuning a runaround path
When you choose Auto Image, Embedded Path, Alpha Channel, Non-White Areas,
or Same As Clipping from the Type drop-down menu (Item > Runaround) (Windows),
or the Runaround tab of the Measurements palette (Mac OS X), the following fields
let you manipulate the runaround path:
1
Outset changes the size of the runaround path. Positive values result in a runaround
path that is further from the original setting, negative values decrease the amount of
image included in the runaround path.
2
Noise lets you specify the smallest allowable closed path. Any closed path smaller than
the noise value is ignored. Noise values are useful for cleaning up runaround paths
and making them easier to output.
3
Smoothness lets you control path accuracy. A lower value creates a more complex
path with a greater number of points. A higher value creates a less accurate path.
4
Threshold determines how "white" is defined. All pixels defined as "white" are excluded.
For example, if the Threshold value is 20%, and a pixel's gray value is below or at
20%, the pixel will be considered "white" and excluded from the runaround path.
Editing a runaround path
To adjust a runaround path, check Runaround (Item > Edit). The runaround path
displays as a magenta outline. You can then edit the path as you would any Bézier
object.
