Creating a Linear Barcode
To create a Linear 1D Barcode (must have a DIB open), move to the menu item: Barcoding --> Write 1 Barcode à Write Barcode to Rectangle.
Information to be encoded. The Barcode standard specifies which characters can be entered in this field.
Which barcode standard the barcode will be created with.
Orientation of the barcode.
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.
Left (X); Top (Y):
Coordinates in pixels that the barcode will be placed on the bitmap.
Width (X); Height (Y):
The size in pixels that the barcode will be upon creation.
Detect Largest Empty Rectangle:
Finds the largest available area on the open and active bitmap for a barcode to be placed.
If checked, this option will cover any information beneath the barcode.
Toggles whether the text value of the barcode will be shown or not.
Reading all Linear 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.
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.
Defines the area (left, right, top and bottom of the box) where barcodes will be scanned for.
Detecting the Orientation of One Linear 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).
The 1D Barcode SDK/ActiveX contains a variety of sample applications, which demonstrate the capabilities and features of the toolkit. The product is fully .NET compatible and also provides sample source code written in C#, VB.NET, and J# to demonstrate the powerful document conversion options.
Operating Systems Supported:
32-bit Windows Server 2003 family, XP, 2000, NT 4.0 and ME/98/95.
