Modify Grid Measurement/Create a New Grid Dialog Box

Use this dialog box to specify the exact position and dimensions of a new or existing barcode or graybox grid.

TIP: If you are using an imaging scanner, you may find it more convenient to draw graybox and software bar code grid evaluation regions and clip regions directly in the grid definition area.

Grid Location

View information about the grid. The values in this area cannot be changed.

Field – shows the name of the field this grid is appended to.
Sheet – shows the sheet number on which this grid is located.
Side – shows the side of the sheet, Top or Bottom, on which this grid's evaluate region is located. The side on which the clip region is located (if different) is not displayed.

Unit of Measurement

Select the measurement system used to define the exact coordinates for the location and size of the grid, relative to the document's origin point (the intersection of the leading edge and guide edge of the form). The selection made here is used in the Evaluate Region and Clip Region, X and Y Region Position areas. Choices are:

Cell/TM Position – Read cell and timing mark numbers. Locations are measured to specified Cell/TM response position centers then clip and evaluate regions are automatically enlarged by ScanTools to include complete OMR response positions.
.001 in – Thousandths of an inch. Locations are measured from the origin point in thousandths of an inch.
Hybrid .001 in – A combination of read cell and timing mark numbers and thousandths of an inch. Base locations are measured to specified Cell/TM response position centers and then clip and evaluate regions are enlarged by the amount you specify, defined in thousandths of an inch. When this is selected, an additional Hybrid control, Hybrid Offset, appears in this dialog box.
.01 mm – Hundredths of a millimeter. Locations are measured from the origin point in hundredths of a millimeter.
Hybrid .01 mm – A combination of read cell and timing mark numbers and hundredths of a millimeter. Base locations are measured to specified Cell/TM response position centers and then clip and evaluate regions are enlarged by the amount you specify, defined in hundredths of a millimeter. When this is selected, an additional Hybrid control, Hybrid Offset, appears for Evaluate Region and Clip region (see below for details).

Special Unit of Measurement Considerations

iNSIGHT 2/4 (with Imaging) Scanners

As absolute Units of Measurement (.001 in and .01 mm) is an advanced feature of ScanTools Plus software, using the full capabilities of iNSIGHT 2/4 (with Imaging) scanners, ensure that your scanner includes the advanced features in scanner Manufacturing Level ML013 or greater.

To verify your scanner Manufacturing Level, look at the serial number label on the back of the scanner and read the “ML” number.

If the ML number is less than ML013, call Scantron Customer Support to arrange to have your scanner enhanced to this Manufacturing Level.

For International users, contact your local sales representative.

Forms Without Timing Marks

If you are using forms without timing marks, you must use an absolute Unit of Measurement (.001 in or .01 mm) to specify Evaluate Region and Clip Region locations. Cell/TM and Hybrid Units of Measurement cannot be used since they require the presence of timing marks.

iNAME Scan-Time Archiving
If you are using iNAME image archiving, using sparse (grid) clipping for grayboxes or software bar codes is not compatible with use of absolute (.001 in or .01 mm) or Hybrid units of measurement:
- If any of the Selected Images to Archive specified in the iNAME Configuration are for sparse clips of grayboxes or software bar codes that use an absolute unit of measurement (.001 in or .01 mm), iNAME will fail at scan time ("Problem taking clips" error) and scanning will stop.
- If the Selected Image to Archive is for a sparse clip of a graybox or software bar code that uses hybrid units of measurement, iNAME uses only the Cell/TM Position values for the clip. The Hybrid Offset values are not used.

OMR/Merge Horizontal Adjustment

No horizontal adjustment is made for background form merging if you use absolute units of measurement (.001 in or .01 mm) for the locations of Standard Graybox, ICR/OCR Graybox, or software bar code Evaluate Regions and Clip Regions. You must use cell/TM position units of measurement.

ScanFlex
No horizontal adjustment is made for background form merging if you use absolute units of measurement (.001 in or .01 mm) for the locations of Standard Graybox, ICR/OCR Graybox, or software bar code Evaluate Regions and Clip Regions. You must use cell/TM position units of measurement. To accommodate this, we recommend you:
- Use dropout colors for lines, boxes, and text in a form area that is resolved as a Standard Graybox, ICR/OCR Graybox, or software bar code. See ScanFlex Form Design Rules.
- Define a larger Evaluate Region and Clip Region to make sure the entire area is included.

User Exits
User exits are not compatible with applications that contain grayboxes or software bar codes that use absolute (.001 in or .01 mm) or Hybrid units of measurement:
- If the user exit examines a graybox or software bar code absolute unit of measurement (.001 in or .01 mm), it will interpret it as an invalid value.
- If the user exit examines a graybox or software bar code hybrid unit of ueasurement, it will use only the cell/TM position values for the clip. The hybrid offset values will not be used.
User exits are compatible with applications that contain grayboxes and software bar codes that use cell/TM unit of measurement or that do not examine the graybox or software bar code unit of ueasurement values.

Clip and Evaluate Regions

Select the dependency of the Clip and Evaluate regions of the graybox or software bar code. The clip region is the graphic image clip of the graybox or software bar code and is used for viewing in the post-scan editor or for archiving as a separate graphic file. The evaluate region is the area of the graybox or software bar code that is evaluated at scan time for the presence of data. Graybox data presence is based on the Cutoff Value defined in the Graybox tool. Software bar code data presence is based on decoding defined in the Bar Code tool. Choices are:

Clip Region Tracks Eval Region – the Clip Region is identical to whatever is entered in the Evaluate Region. You cannot enter values for the Clip Region.

Show me

Clip Region is Unique – each region is independent and can differ from the other. This choice allows you to enter different values for the Evaluate Region and Clip Region.
- If the Clip Region is on the same sheet side as the Evaluate Region, you can define the position in this dialog box or you can draw the Clip Region in the grid definition area. You can use any Unit of Measurement.
- If the Clip Region is not on the same sheet side as the Evaluate Region, you must draw the Clip Region in the grid definition area. You must use Cell/TM or Hybrid Unit of Measurement.

CAUTION: If the clip region of an ICR/OCR graybox does not fully encompass the evaluate region, phantom clips will not be saved for that ICR/OCR graybox.

Evaluate Region

Use these controls to define the X and Y coordinates for two opposite corners of the evaluate region of the graybox or software bar code. This defines the exact location and size of the evaluate region.

For the Top side of a sheet, enter X and Y coordinate values for Upper Left and Lower Right corners.
For the Bottom side of a sheet, enter X and Y coordinate values for the Upper Right and Lower Left corners.

Use this element…	…to…
X (Cell or .001" or .01 mm)	Enter the value that represents the location of the corner of the evaluate region, along the X axis of the form. This is the read cell number, number of inches in thousandths, or number of millimeters from the guide edge of the form. The minimum values are 1 for Cell and 0 (zero) for .001" or .01 mm. TIP: We recommend using minimum values of 1 for Cell, 50 for .001", and 120 for .01 mm.
Y (TM or .001" or .01 mm)	Enter the value that represents the location of the corner of the evaluate region, along the Y axis of the form. This is the timing mark number, number of inches in thousandths, or number of millimeters from the leading edge of the form. The minimum values are 1 for TM and 0 (zero) for .001" or .01 mm. TIP: We recommend using minimum values of 1 for TM, 65 for .001", and 155 for .01 mm.
+X (.001" or .01 mm) (Hybrid only)	Enlarge the region identified as the corner of the evaluate region (along the X axis of the form) in increments of either thousandths of an inch or hundredths of a millimeter on the X axis.
+Y (.001" or .01 mm) (Hybrid only)	Enlarge the region identified as the corner of the evaluate region (along the Y axis of the form) in increments of either thousandths of an inch or hundredths of a millimeter on the Y axis.

CAUTION: If you use a value less than the recommended minimum value for X or Y with .001" or .01 mm units of measurement, the image may contain black (and possibly garbage) from the buffer.

Clip Region

Use these controls to define the X and Y coordinates for two opposite corners of the clip region of the graybox or software bar code. This defines the exact location and size of the clip region.

For the Top side of a sheet, enter X and Y coordinate values for Upper Left and Lower Right corners.
For the Bottom side of a sheet, enter X and Y coordinate values for the Upper Right and Lower Left corners.

Use this element…	…to…
X (Cell or .001" or .01 mm)	Enter the value that represents the location of the corner of the evaluate region, along the X axis of the form.
