USING ACROBAT X PRO 190 Forms 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. 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. Last updated 10/11/2011
