Settings tab - Properties of Bar Code Locator window

Bar Code Locator icon The Bar Code Locator extracts bar code data from documents. Some documents contain bar codes that are attached to a form during the scanning process as a stamp or sticker. Other documents contain bar codes as part of the document itself. The Bar Code Locator can locate the most common bar code types automatically, even if they are rotated or inverted.

Use the following settings to enhance bar code recognition:

Bar Code Type

This group contains a list of bar code types. At least one bar code type is required. (Default: Auto detect)

Use the default value only if you do not know the expected bar code types. This is because the Auto detect value negatively impacts the performance and accuracy of bar code recognition and includes only a subset of the full list of available bar code types.

For the best results, select one or more specific bar code types from this list and then use the page number or a region to narrow down the bar code location. This ensures that recognition is more likely to find a bar code. If you are recognizing multiple bar codes in multiple locations, use a separate Bar Code Locator for each bar code, restricting the search area using specific page numbers and regions.

When Auto detect is selected, all other bar code types are unavailable. If you clear the Auto detect value, select one or more of the bar code types. When testing the locator, any recognized bar codes are displayed on the Test tab along with their bar code type, confidence, value, and page location.

You can select only one of the Code 39 or Code 39 without start/stop character bar code types.

1D Bar Code Settings
The following settings are available to further configure 1D bar codes:
Enable checksum

Select this setting to help reduce errors if the bar code is misinterpreted. (Default: Cleared)

Min. length to avoid misrecognition

Set minimum length of a valid bar code. This ensures that bar codes with a shorter length are not included in the recognition results. (Default: 3)

This setting is not related to the Min. length setting on the General tab. The Min. length setting filters the recognition results based on its value, whereas this setting does not include bar codes in the recognition results unless they have the specified length.

The following buttons are available at the bottom of this window:
