l Disable rewriting: Check to prevent a field that has already been written in to accept any further ink data. This is
useful only if forms are sometimes partially processed or are processed multiple times until all mandatory fields (or a
final field) are completed. The rewriting is only disabled after the pen has been docked (in a different session), which
means there is no warning when writing on a non-rewrite field.
Considerations
There are some important considerations when using the capture field object in a PlanetPress Design document:
l Capture Fields should always be set to print on top of any other object and should not be hidden. Placing another object
over a Capture Field may cause unexpected behaviors in reading pen data.
l Capture Fields are complex and ink-intensive. They consume a fair amount of ink and take a lot of time to process
when present. This means it is recommended only to use fields when necessary, and not to make it any larger than you
need it.
l When you add one or more Capture Fields to a page, a copyright notice automatically appears on the page indicating
that the Anoto technology is being used. This notice must remain visible at all times and hiding it constitutes a violation
of the PlanetPress Suite End User License Agreement (EULA). You can change the position of this notice in your doc-
ument's properties (see the Resources Options section in "Set Up a Document" (page 105)).
l If all of the fields in a Capture document are set to be Final, they will react the same as if they were all Optional.
l Capture Fields are not supported with the N-Up feature of PlanetPress.
l There is a 7mm (1/3 inch) wide area on each side of a field the pen may not be able to recognize depending on the direc-
tion and angle at which the pen is held while writing. In order to prevent the majority of writing errors, you can place a
thin white border, 7mm from the sides of your fields. The white line will not confuse then pen and anyone writing in the
field will naturally write within the box created, avoiding the 7mm area. For the same reason, the minimum size of a
Capture field is 2/3 inch (14mm).

Pidgets
Pidgets are special static patterns you can print on a page to use with the Anoto Digital Pen. When the pen "writes"over those
specific patterns, options are triggered as the pen recognizes them. In other words, pidgets are triggers for the pen's features
and are limited to what features the pen actually has.
The pidgets themselves are small EPSfiles that are printed as an image. Once printed, pidgets can be re-used multiple times.
This is because the pidgets are printed in true black which the pen recognizes even if there have been multiple color pen
marks on top of them.
To activate a pidget, simply place the pen inside of the pidget's icon and press down. Generally, there is no need to move the
pen or write anything, the pen can detect the pattern. When the pen successfully reads a pidget, it vibrates twice in quick suc-
cession.
