Using the 1D Barcode Samples

Creating a Barcode

To create a Linear 1D Barcode (must have a DIB open), move to the menu item: Barcoding > Write 1 Barcode > Write Barcode to Rectangle.

Barcode Standard	Which barcode standard the barcode will be created with.
Barcode String	Information to be encoded. The Barcode standard specifies which characters can be entered in this field (Text Input radio button is checked) or contained by file (File Input radio button is checked).
Unit	The Offset and Size can be shown in different units: pixels, millimeters or inch/100.
Align	The barcode can be aligned to one of the corners of drawing area. The user can select “Left-Top”, “Right-Top”, “Left-Bottom” or “Right-Bottom” corner.
Offset	Distance from the aligned corner in X and Y direction, in the chosen unit.
Size	“Large”, “Medium” or “Small” barcode can be chosen, the “Width” and “Height” fields show the size in the chosen units. Other size can be set directly in a separate dialog, invoked by “Advanced Settings” button.
Direction	Orientation of the barcode (Left-Right, Right-Left, Top-Bottom or Bottom-Top).
Preview	This fields shows (with grey rectangle) the current position of barcode on the whole document.

Pressing the “Advanced Settings” button, the following dialog appears:

Width of thinnest bar	Defines in pixels how wide the smallest modules will be
Width of thinnest space	Defines in pixels how wide the smallest white space will be between modules.
Neighboring level distance	Specifies the length of each character’s barcode value.
Empty Frame Size	The amount of white space above the barcode in the given rectangle.
Opacity	If checked, this option will cover any information beneath the barcode.
Show Text	Toggles whether the text value of the barcode will be shown or not.

Reading all Barcodes

To read all available 1D barcodes, navigate to: Barcoding > Detect And Decode All Barcodes

Dilation Matrix Size	May help rectify damaged barcode samples by increasing this number. Dilation may help fill holes or inaccuracies in the barcode.
Minimal Bar Number	Minimum number of lines mandatory in order to detect as a barcode.
Enlarge Percent	The percent of enlargement required to detect and read the barcode.
Minimal Side Length Ratio	Specifies the minimal ratio of longer to shorter in order to recognize the element as a barcode.
Maximal Distance Ratio	How far two barcodes must be apart in order to read them as separate barcodes.
Maximal Angle Difference	The maximum amount that a single barcode may be bent and still be read.
Search Area	Defines the area (left, right, top and bottom of the box) where barcodes will be scanned for.

Detecting the Orientation of One Barcode

To find the angle of orientation if there is only one barcode on the bitmap select: Barcoding > Detect Barcode Orientation. A dialogue will appear as shown below indicating the orientation of the barcode that was found.

Detecting the Largest Available Area for a New Barcode.

To automatically detect the largest area click: Barcoding > Detect Largest Empty Rectangle. A dialogue box will appear as seen below with the appropriate information:

Reading only one barcode by orientation.

To read one barcode by the orientation: Barcoding > Read 1 BarCode > Automatic Horizontal/Vertical Reading. Specify which Direction (orientation) to search for and the search area by entering Left, Right, Top and Bottom coordinates. If more then one barcode fits the criteria, the first available barcode will be displayed.

This option may also be chosen to target a specific standard barcode by clicking: Barcoding > Read 1 BarCode > Horizontal/Vertical Reading > (the specific standard barcode).

Reading any one first available barcode.

To read one barcode with any orientation: Barcoding > Read 1 BarCode > Automatic Skewed Reading. Simply specify the coordinates to be scanned for a barcode.

This option may also be chosen to target a specific standard barcode by clicking: Barcoding > Read 1 BarCode > Skewed Reading > (the specific standard barcode).
