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.
|
Barcode String |
Information to be encoded. The Barcode
standard specifies which characters can be entered in this
field. |
|
Barcode Standard |
Which barcode standard the barcode will
be created with. |
|
Direction |
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. |
|
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 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. |
|
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
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).
Sample
Applications:
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.
