Zone Configuration
The ribbon menu has the following buttons.
Group | Button | Description |
---|---|---|
Zones | Save Zone Settings |
Saves the zone settings for the current profile. |
Template | Select Template Image |
Loads a template image for the current profile. Supported image types are: TIF, TIFF, JPG, JPEG, JP2, PDF, PNG, BMP, GIF. |
Capture Template Image |

The following toolbar commands are available for zone creation above the viewer pane.
Toolbar button | Description |
---|---|
![]() |
Standard mouse pointer (selected by default). |
![]() |
Manually draw an OCR zone. |
![]() |
Manually draw and OMR zone. |
![]() |
Manually draw a Smart Zone. See OCR Smart Zone Configuration. |
![]() |
Manually draw a smart OMR zone. |
![]() |

Auto Sized Zones |
Select from a list how to draw a new zone on the described area. You can define dynamic zones (Full Page, Bottom Half, and so on) that change size based on the size of the image being processed. When adding a new Auto Sized Zone, you are prompted to select whether you want this zone to be a dynamic zone. If you want to change the dynamic zone setting on an existing zone, click the
Dynamic zones are not limited to just zones created using the Auto Sized Zone list. Any standard zone or Smart Zone can have the Enable dynamic bounds... setting enabled. |
![]() |
Repeat a zone (use this function to speed up OMR configuration). |
![]() |
Delete the selected zones. Users can use the delete key on their keyboard to delete the selected zone. |
Grouping Tools |
Group multiple zones for OMR purposes.
|
Zone Display |
Display either all zones or only the selected zone. |
![]() |
Select an area to zoom to. |
![]() |
Increase or decrease the size of the image. |
![]() |
Rotate the document image left or right. |
The General tab opens by default, where you can define and configure zones.
To define zones, zoom in to the desired area on the viewer pane (with the Zoom In toolbar icon), then select the Draw Zone toolbar icon and draw the zone.
Drawn zones are listed in the Zones pane. Name the drawn zone and fill out which page of the document it is expected to be found on. The zones in the list can be used anywhere in the program where the user can define zones.
The page and resolution of the template are displayed at the bottom of the screen. They must match the actual page and resolution at capture time.
In the Zones pane, a set of icons are available.
Icon | Description |
---|---|
![]() |
Opens the OCR Smart Zone Configuration dialog box and allows editing of child zones, anchors, and more. |
![]() |
Deletes the zone. If a zone is in use by any capture profile, the zone cannot be deleted. |
![]() |
Applies image processing to the zone template image. |
![]() |
Previews OCR (printed text), ICR (handwritten text), MICR (E-13B), or MICR (CMC-7) results in the selected zone. |
![]() |
Ungroups a cluster of child zones contained within the selected zone (child zones are used for OMR purposes). |
![]() |
Opens a dialog box, where you can configure the advanced settings of the zone, depending on the used recognition engine. This description is for the OmniPage engine. Enable spell check: This feature accounts for everyday norms when generating results. For example, spell check ensures a number such as 34567 would not be read as 34S67, as it is unlikely that the letter S would appear within a list of numbers. If your images are of high quality (computer-generated) and a zone contains data that breaks everyday norms (in the example above, contains letters and numbers) disable this option for the zone to improve your OCR results. Enable vertical dictionaries: Vertical dictionaries are seen in the legal, medical, and financial fields, and the OmniPage engine supports several languages with vertical orientations. Text direction: Specify the direction of the text for the OmniPage OCR engine to read from:
Auto-detect hand-printed text (ICR): Automatically detect hand-printed text (ICR) and adjust recognition settings accordingly. This feature is an enhanced version of the legacy feature "Machine Print Font Type - Unknown". Only subregions classified as machine print are further processed. Hence, there is some risk that low-quality machine print subregions are missing in the final result, for they might have erroneously been classified as handwriting. Enable dynamic bounds for this zone...: Automatically resize zones based on the dimensions of the captured page. For example, if a zone is defined to encompass the top half of an 8.5" x 11" page, and an 8.5" x 5" page is captured, the zone's height is automatically adjusted to cover only the top half of the page. |

Opens a dialog box, where you can configure the advanced settings of the zone, depending on the used recognition engine. This description is for the deprecated RecoStar engine. Enable OCR logical context filtering: OCR logical context filtering enforces logical rules when generating results. For example, the number 4567 would not be read as 4S67, because it is unlikely that the letter S would appear in a list of numbers. If your images are of high quality (computer-generated) and a zone contains data that breaks logical rules, disable this option for the zone to improve your OCR results. Enable OCR Trigram mode: Trigram post-processing uses language model statistics to try and correct recognition results in natural language sequences. Disabling Trigram mode can improve recognition results on zones that contain random sequences of letters and numbers (for example, part numbers, invoice numbers). Machine print font type: The options include Unknown and Machine Type. If Machine Type is selected, machine-print recognition is activated. All text detected in the input area is treated like machine print (handwriting included). Selecting Unknown activates automatic handwriting detection. Only subregions classified as machine print are further processed. Hence, there is some risk that low-quality machine print subregions are missing in the final result, as they might have erroneously been classified as handwriting. Machine type pitch: The options include Unknown and Variable. In rare instances, the default value Unknown can cause misreads in zones that contain a mixture of numbers, characters, and letters. For example, "25-IN" would be read as "254N". In these cases, switch the machine type pitch to Variable. Enable dynamic bounds...: Select this option to automatically resize zones based on the dimensions of the captured page. For example, if a zone is defined to encompass the top half of an 8.5" x 11" page, and an 8.5" x 5" page is captured, the zone's height is automatically adjusted to cover only the top half of the page. |

On the Anchoring tab, clicking Add opens the Zone Anchor Configuration dialog box, where you can configure zone anchors.
Select from the following anchor types:
-
Default (Top Left of Page)
-
Fixed Point
-
Bar Code
-
Patch Code
-

If the user uses a bar code or patch code, the type and pattern selected must match.
Other configuration options are listed below.
The available options depend on the selected anchor type.
-
Page image: Select main, original, or alternate image.
-
Alternate image tag: Enter the tag name to be associated with the alternate image.
-
Bar/Patch code type: Select between various supported types of bar codes or patch codes.
-
Bar code pattern: Enter the bar code value for the bar code intended to use for anchoring.
-
Patch code number: Set Nth patch code on the page intended to use for anchoring.
-
Zone OCR text: Enter specific text for OCR to detect.
-
Zone to search: A list of areas where the anchor can be searched for.
-
Preview recognition language: A list of supported languages to be used for Zone OCR purposes.
