224 ADOBE ACROBAT 3D VERSION 8
User Guide
Font Size Sets the size of user-entered text or of the selection marker for radio buttons and check boxes. The choices
include Auto, various preset values, and typing in a different value.
Text Color Opens a color picker in which you can select a color swatch for the text or selection marker.
Font Lists the fonts available on your computer. This option is not available for form fields that do not display text.
Note: The Enable Right-To-Left Language Options in the International panel of the Preferences dialog box affects what
appears in the Appearance tab of the Properties dialog box. When that preference is selected, the Appearance tab includes
options for changing the digit style (Western or Arabic-Indic) and text direction for text fields, combo boxes, and list
boxes.
Options tab for form field properties
The options available on this tab change according to the type of form field selected. The Options tab appears for all
form field types except digital signatures.
Barcode
The Options tab for barcode field properties contains the following:
Symbology Includes the PDF417, QR Code, and Data Matrix barcode types.
Note: If your organization processes forms by multiple methods, select the method that accommodates the lowest quality
barcode images. For example, if forms will be returned by fax and mail, choose Fax Server as the decode condition to
ensure high read rates on all forms.
Compress Data Before Encoding To Barcode Specifies that data will be compressed before it is encoded. Data is
compressed with the Flate compression method. Compressed data usually requires less storage space in the barcode,
allowing more data to be stored. In general, select this option if you will use the Acrobat barcode forms decoder to
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.
