interpret the returned data. Do not select this option if you will use a handheld barcode scanner, because most of these
cannot decode compressed data.
Decode Condition The preset decode conditions represent recommended starting points that you can adjust by
clicking the Custom button.
Custom Opens a dialog box in which you can select custom processing parameters that are best for your specific
scanning and faxing hardware. (The available options vary according to barcode types.)
X Dimension Width, in mils (1 mil = 0.001 inch or 0.0254mm), of the cell.
Y/X Ratio Height/width ratio of the cell. For example, for a data cell that is twice as high as it is wide, enter 2. (Available
only for PDF417 barcodes.)
note: If you are planning to decode the barcode using a handheld laser scanner, avoid creating barcodes wider than 4 inches
(10.2 cm). Taller and narrower barcodes generally work better with handheld scanners. Barcode height and width will not
be an issue if you are using an Adobe barcode decoder (available separately).
Error Correction Level Corresponds to the level of data redundancy that is added to the barcode to correct any potential
decoding errors. Higher levels provide more redundancy and a more robust barcode that will generate more successful
decode results. However, higher levels will also result in a larger barcode and a reduced ability to encode user-supplied
or form structure data into the barcode. A more robust barcode can reduce problems created by pen marks, poor print
quality, degradation caused by fax transmission, or folds in the document. This option is available for PDF417 and QR
Code barcodes.
Manage Barcode Parameters Enables you to save your custom barcode selections in a file. You can then export the file
and make it available to other form authors in your organization.
Check boxes
Check Box Style Specifies the shape of the marker that appears inside the check box when the user selects it: Check (the
default), Circle, Cross, Diamond, Square, or Star. This property does not alter the shape of the check box itself.
note: The size of the marker inside the check box is determined by the size of the font you specify in the Appearance tab.
Export Value Specifies a value to represent the item if the data will be exported. If left blank, the entry for Name in the
General tab is used as the export value.
Check Box Is Checked By Default Shows the check box selected unless the user deselects it.
Drop-down and list box
For either dropdown boxes or list boxes, you use the Options tab to create a list of items from which the user selects.
Although most of the properties on this tab are common to both these types of form fields, a few are exclusive to one
type or the other.
Item Accepts the text that you type for options that you want to appear in the menu for the field.
Add Moves the current entry in Item to the Item List.
Export Value Where you type in a value to represent the item if the data will be exported. If left blank, the entry for
Name in the General tab is used as the export value.
Item List Displays the choices that will be available in the list.
note: The highlighted item in the Item List box appears as the default selected item in the dropdown box or list box field.
To change the default item, highlight another item from the list.
Up and Down buttons Change the order in which the items are listed in the drop-down list. These buttons are not
available if Sort Items is selected.
