ADOBE ACROBAT 3D VERSION 8 220 User Guide JavaScript code is generated automatically to encode the selected fields in the XML or Tab Delimited format, the Barcode Field Properties dialog box closes, and the barcode for which you specified values appears on the form. Note: If you add a new field to a form after you have created the barcode, the new field will not automatically be included in the data for existing barcodes. However, you can manually include additional data fields in the barcode. Test a barcode field 1 Choose Forms > Edit Form In Acrobat to deselect it, or click the Preview button in the Forms toolbar. 2 Fill in the form, using sample data that represents the maximum amount of information that a each field allows or that you expect any user might enter. 3 If the barcode field is grayed out, follow either the procedure for resizing the barcode field or for adjusting the content data. (See the following tasks.) 4 When you are sure that the barcode field area is large enough to contain all of the incoming data, choose Forms > Clear Form, to remove the sample data, and then choose File > Save. The barcode form field is now ready for distribution. Include additional data fields in the barcode 1 Using either the Barcode tool or the Select Object tool, select the barcode field and choose Forms > Show Field Properties. 2 In the Value tab, do one of the following: • If Encode Using is selected, click Pick, and select additional form fields to be encoded. • If Custom Calculation Script is selected, click Edit, and write additional JavaScript to include the additional fields. After including new data fields in the barcode, be sure that the barcode area is large enough by testing sample data. If the barcode area is grayed out, adjust the barcode size, barcode properties, or text field properties so that the data content fits into the barcode area. Resize a barcode field The most common error when authoring barcoded forms is when the barcode area is too small to accommodate the data. If this occurs during your test of sample data, the barcode appears as a solid gray rectangle instead of showing its coding pattern. 1 Select the Barcode tool , and select the barcode field. Important: Be sure to use only the Barcode tool to resize a barcode. If you resize a barcode using the Text Field tool or the Select Object tool, the barcode can be distorted and becomes unusable. 2 Drag a handle along the edges or corners of the barcode field frame. 3 If necessary, drag the barcode from inside its frame to move it to another location on the page. Adjust data content to fit in a barcode field 1 To edit the barcode properties so that it can accommodate more data, select it, choose Forms > Show Field Properties, and do any of the following: • In the Options tab, click the Custom button and enter lower values for Error Correction Level and Y/X Ratio. • In the Options tab, select Tab Delimited rather than XML as the data-encoding format. XML requires more barcode area to encode information than Tab Delimited does.
