Bar Code Field Objects This dialog allows you to format a field code or formula as a bar code. Symbology Select the bar code symbology (format) you wish to apply to the field or formula from the drop down list. Text Alignment Controls where the text will appear with the bar code. The default setting is for the bar code text to appear centered below the bar code. The text may also be arranged above or to the right or left of the code or removed altogether. Text may appear either upright (normal) or upside down. Some bar code symbologies require or offer optional checksum bars. These may be selected from the available list. Some bar code symbologies offer various levels of error correction. The higher the level of correction the more likely that a bar code can be read under adverse conditions. However, higher correction levels generally result in larger bar codes. Some bar code symbologies have supplemental codes. These may be selected here if required by your application. This controls the width ratio of the bar code. Wider bars are easier to read on less sophisticated scanning equipment but also occupy more room. Controls the physical width of the individual bars of the bar code. The default setting is a width of 1 unit. You can enter the data you wish to bar code here for testing purposes. Some symbologies are unable to code letters of the alphabet or special symbols such as punctuation marks. Other bar codes require a specific number of digits or other special character arrangements. Use this feature as a quick to test to see if the bar code symbology you have selected will work with your data. For a more thorough explanation of the capabilities and limits of each bar code symbology see the reference below. Test Press this button to test your sample data. If a bar code can be successfully created it will appear in the Preview window. ____________________________ Related Topics |
