    How to use bearer bar?

    You can add horizontal and vertical bearer bar by change the width of BearerBarHorizontalWidth and BearerBarVerticalWidth properties. The unit of width is X-Dimension.
    For examples:
    Image Description
    using horizontal bearer bar in barcode images, no vertical bearer bar. BearerBarHorizontalWidth = 1
    BearerBarVerticalWidth = 0
    using horizontal and vertical bearer bar in barcode images. BearerBarHorizontalWidth = 1
    BearerBarVerticalWidth = 1


    How to modify Human Readable String?

    Human Readable String can be modified by the following parameters:
    ShowHumanReadableText sets to show the Human Readable Text.
    Font sets the font of human readable string.
    HumanReadableTextPosition sets the space between the human readable string and the barcode in inches.
    HumanReadableTextFontColor sets the caption color.
    IsHumanReadableTextOnTop sets the location of human readable string.

    For examples:
    Image Description
    don't show human readable text in bar code image. ShowHumanReadableText = false
    show human readable text in bar code image and change the color and font of bar code. ShowHumanReadableText = true
    Font = new Font("Times New Roman", 8)
    HumanReadableTextPosition = 0.2
    HumanReadableTextFontColor = Color.Red
    IsHumanReadableTextOnTop = false
    move human readable text in bar code image to top and change the color and font of of bar code. ShowHumanReadableText = true
    Font = new Font("Times New Roman", 8)
    HumanReadableTextPosition = 0.2
    HumanReadableTextFontColor = Color.Red
    IsHumanReadableTextOnTop = true


    How to use Caret?
    The UseCaret propeties is set to true by default which is only applied to Code128, UccEan128, Sscc18, Scc14, PDF417, MacroPDF417, QR Code, and DataMatrix etc. where full ASCII is accepted as encoding. The 3 digits data following the caret will be treated as ASCII code, e.g. ^010 is \\n.
    For Code 128, UccEan128, if the FNC1 (ASCII 202) is used, human readable parentheses can be added to the CodeData manually by using the following ASCII code

    ^222 = (XX)
    ^223 = (XXX)
    ^224 = (XXXX)
    ^225 = (XXXXX)
    ^226 = (XXXXXX)
    ^227 = (XXXXXXX)

    The ^222, ^223, ^224, ^225, ^226, ^227 will be transfer to FNC1 (ASCII 202) in the barcode, and the parantheses will be added to human readable text by the digits. The FNC1 can also be added by using ^202 (ASCII 202), or . For example, CodeData ="0123456789" is the same as CodeData ="^2020123456789".

    BarcodeProComponent will automatically identify AI by using the predefined AI table above. However, you can overwrite the predefined AI by using caret (^).

    For example, to encode (012)345678, the data of ^223012345678 would be used to overwrite the default (01)23456789.


    Can I use DataBinding with BarcodeComponent?
    Yes. You can drag the data field from data source and drop it to the BarcodeComponent control and the databinding is automatically added.



    BAR CODE BASIC

    CodaBar Specification
    Codabar is a linear barcode symbology developed in 1972 by Pitney Bowes Corp. It is also known as Codeabar, Ames Code, NW-7, Monarch, Code 2 of 7, Rationalized Codabar, ANSI/AIM BC3-1995 or USD-4.

    Encoding
    Codabar can encode the digits 0 through 9, six symbols (-:.$/+), and the start/stop characters A, B, C, D, E, *, N, or T. The start/stop characters must be used in matching pairs and may not appear elsewhere in the barcode. Codabar is used in libraries, blood banks, the overnight package delivery industry, and a variety of other information processing applications.

    Each character is comprised of 7 binary identifiers (4 bars and 3 spaces). Each identifier or element is made up of a certain multiple of constant-width modules. Different specifications allow for different width modules, the smallest being 0.0065 inches, allowing 11 characters per inch to be encoded. Logical 0s and 1s are represented by narrow and wide elements respectively.

    Codabar Character Set
    The numbers in the table correspond to the width of the element. A 0 means the element is narrow, and a 1 means the element is wide.

    Code 11 Specification

    Code 11, also known as USD-8, was developed as a high-density numeric-only symbology. It is used primarily in labeling telecommunications equipment. The symbology is discrete and is able to encode the numbers 0 through 9, the dash symbol (-), and start/stop characters.

    Encoding
    Code 11 Each character is encoded with three bars and two spaces. Of these five elements, there may be two wide and three narrow, or one wide and four narrow. Wide elements represent a binary 1 while narrow elements represent a binary 0.

    Check Sum
    Two check digits, named C and K, are used.  Normally, if the length of the message to encoded is less than 10 characters only one checksum ('C') is used, whereas both 'C' and 'K' are used if the message is 10 characters or longer. The check digits are the result of a Modulo 11 division of the sum of the products of each digit times a weight factor.  The weights for the C check digit range from 1 to 10 while the weights for the K check digit range from 1 to 9.  Weights start at the right end of the data and increment towards the left.  The dash character has a value of 10 for purposes of check digit calculation.

    Code 11 Character Set
    The numbers in the table correspond to the width of the element. A 0 means the element is narrow, and a 1 means the element is wide.

    ASCII
    CHARACTER
    ENCODING(Bar, Space, Bar, Space, Bar)
    000001
    110001
    201001
    311000
    400101
    510100
    601100
    700011
    810010
    910000
    -00100
    Start/Stop00110

    Since the first and last element of every character is always a bar, a narrow space is appended at the end of each character to separate the last bar of a character from the first bar of the character that follows.

    The complete barcode is concatenating a start character + data + C + K + stop character.



    Code 11 examples by using BarcodeComponent
    [C#]

    	using BarcodeComponent.Winform; 
    
    	//create barcode class

    Code 128 Specification

    Code 128, also known as ANSI/AIM 128, USS Code 128 is a continuous, multilevel, full ASCII code.

    Encoding
    Code 128 There are three types of code 128 encoding. Type A provides the character set of all upper case alphanumeric characters plus all of the ASCII control characters. Type B provides the character set of all upper and lower case alphanumeric characters. Type C provides increased density for numeric encoding with double density numeric characters for all number pairs from 00 to 99.

    Check Sum
    Code 128 symbology must include a checksum digit. The steps for calculating the check digit are as follows: Add the start character value(103, 104, or 105) to the running checksum. Take each character in the message, take its value, and multiply it by its character position, and add the total to the running checksum. The checksum digit is the result of running checksum modulo 103.

    Use Caret (^)
    The UseCaret propeties is set to true by default which is only apply to Code128, UccEan128, Sscc18, Scc14, PDF417, MacroPDF417, QR Code, and DataMatrix etc. where full ASCII is accepted as encoding. The 3 digits data following the caret will be treated as ASCII code, e.g. ^010 is \\n.
    For Code 128, UccEan128, if the FNC1 (ASCII 202) is used, human readable parentheses can be added to the CodeData manually by using the following ASCII code

    ^222 = (XX)
    ^223 = (XXX)
    ^224 = (XXXX)
    ^225 = (XXXXX)
    ^226 = (XXXXXX)
    ^227 = (XXXXXXX)

    The ^222, ^223, ^224, ^225, ^226, ^227 will be transfer to FNC1 (ASCII 202) in the barcode, however, the parantheses will be added to human readable text by the digits. For example, to encode (01)2345678, the data of ^222012345678 would be used.

    Code 39 / Ext Specification

    Code 39, also known as ANSI/AIM Code 39, USS Code 39, Code 3 of 9, is a discrete, variable-length symbology. Code 39 is an alphanumeric bar code. The symbol can be as long as necessary to store the encoded data. It is designed to encode 26 uppercase letters, 10 digits and 7 special characters. It can be extended to code all 128 ASCII characters by using a two character coding scheme.

    Encoding
    Code 39 is called code 39 or three of nine because each character encoded is made up of 5 bars and 4 spaces for a total of 9 elements and 3 out of 9 element are always wide.

    Check Sum
    In applications that require very high level of accuracy a modulo 43 check sum digit is appended to the last character.

    Code 39 Character Set
    Code 39 starts with '*' and stops with '*'. Code39 is designed to encode 26 upper case letters, 10 digits and 7 special characters:

    Code 39 Extended: The code 39 symbology can be extended to encode all 128 characters in the ASCII table. In the full ASCII mode, the symbols $ / % and + are used as precedence codes with the 26 letters as shown below. Since the same symbol now can be interpreted as one character in Extended Code 39 mode and two characters in Code 39 mode, the readers must be set to extended mode to read the data correctly.

    Code 93 / Ext Specification

    Code 93, also known as ANSI/AIM Code 93, USS Code 93 is a continous, variable-length symbology. code 93 is used primarily by Canadian postal office to encode supplementary delivery information. Every symbol includes two check characters. Code 93 has a native character set of 26 upper case letters, 10 digits and 7 special characters.

    Encoding
    In Code 93, the number "1" represents a "dark" or "bar" section of the bar code whereas a "0" represents a "light" or "space" section of the bar code. Thus the numbers 1101 represents a double-wide bar (11), followed by a single-wide space (0), followed by a single-wide bar (1).

    Check Sum
    Every code 93 symbol must include two check characters which are referred to as "C" and "K". These two check characters immediately follow the encoded message itself and immediately precede the final stop character.

    Code 93 Character Set
    Code 93 starts with '*' and stops with '*'.

    Interleaved 2 of 5 Specification

    Interleaved 2 of 5, also known as 2 of 5 Interleaved, 2/5 Interleaved, ANSI/AIM ITF 25 or ITF, is a continuous two-width barcode symbology encoding digits. It is suitable for encoding general purpose all-numeric data and is used primarily in the distribution and warehouse industry.

    Encoding
    Interleaved 2 of 5 encodes pairs of digits; the first digit is encoded in the five bars ("black lines"), while the second digit is encoded in the five spaces interleaved with them ("white lines"). Two out of every five bars or spaces are wide (hence 2 of 5). As only an even number of digits can be encoded, a 0 is added as first digit.

    Check Sum
    Interleaved 2 of 5 does not require a checksum. It may include an optional Mod 10 check digit.

    Encoding
    Ucc/Ean 128 uses the same encoding as Code 128.

    Use Caret (^)
    The UseCaret propeties is set to true by default which is only apply to Code128, UccEan128, Sscc18, Scc14, PDF417, MacroPDF417, QR Code, and DataMatrix etc. where full ASCII is accepted as encoding. The 3 digits data following the caret will be treated as ASCII code, e.g. ^010 is \\n.
    For Code 128, UccEan128, if the FNC1 (ASCII 202) is used, human readable parentheses can be added to the CodeData manually by using the following ASCII code

    ^222 = (XX)
    ^223 = (XXX)
    ^224 = (XXXX)
    ^225 = (XXXXX)
    ^226 = (XXXXXX)
    ^227 = (XXXXXXX)

    The ^222, ^223, ^224, ^225, ^226, ^227 will be transfer to FNC1 (ASCII 202) in the barcode, and the parantheses will be added to human readable text by the digits. The FNC1 can also be added by using ^202 (ASCII 202), or . For example, CodeData ="0123456789" is the same as CodeData ="^2020123456789".

    BarcodeComponent will automatically identify AI by using the predefined AI table above. However, you can overwrite the predefined AI by using caret (^).

    For example, to encode (012)345678, the data of ^223012345678 would be used to overwrite the default (01)23456789.

    Postnet Specification

    Postnet (Postal Numeric Encoding Technique) is a barcode symbology that is used by the United States Postal Service to assist in directing mail. The Postnet barcode can represent a five-digit ZIP Code( 32 bars),a nine-digit ZIP+4 code(52 bars), or an eleven-digit delivery point code( 62 bars).

    Encoding
    Postnet barcodes encodes the data in half- and full-height bars. And the barcode always starts and ends with a full bar (often called a guard rail) and each individual digit is represented by a set of five bars using a two-out-of-five code. In Postnet, the two bars are full bars.

    Check Sum
    The check digit is based on Mod 10 algorithm. The value of the check digit is that when added to the sum of other digits in the barcode, results in a total that is multiple of 10. For example, the check digit for zip code 54321-6789 is 5 since 1+2+3+4+5+6+7+8+9=45 which adds check digit 5 result a sum 50.

    Postnet Character Set
    The Postnet barcode is numeric only.

    USPS Postnet Properties
    Besides the properties to general barcode, the following properties belongs to Postnet:

    PostnetHeightTall gets or sets tall bar height for Postnet, Planet or USPS Intelligent Mail. Default is 0.127 inch.
    PostnetHeightShort gets or sets short bar height for Postnet, Planet or USPS Intelligent Mail. Default is 0.05 inch.

    PLANET Specification

    PLANET (Postal Alpha Numeric Encoding Technique) was used for the U.S. Postal Service. This US Postal Office uses a combination of the POSTNET code and PLANET code to track customers piece of mail.

    Encoding
    PLANET barcodes encodes the data in half- and full-height bars. And the barcode always starts and ends with a full bar (often called a guard rail) and each individual digit is represented by a set of five bars using a two-out-of-five code. In PLANET, the two-of-five are the short bars.

    Check Sum
    The check digit is based on Mod 10 algorithm. The value of the check digit is that when added to the sum of other digits in the barcode, results in a total that is multiple of 10. For example, the check digit for address code 4012345678901 is 0 since 4+0+1+2+3+4+5+6+7+8+9+1=50 which adds check digit 0 result a sum 50.

    USPS PLANET Properties
    Besides the properties to general barcode, the following properties belongs to PLANET:

    UPC-E Specification

    UPC-E (Universal Product Code version E) is the short form representation of a UPC A. There may be 2-digit or 5-digit Supplement to UPC.

    UPC-E compression rule from UPC-A

    Not all UPC-A numbers can be compressed to UPC-E. These codes who have a corresponding UPC-E code must have at least 4 zeros. The rules are:

    1. If the manufacturer code ends with 000, 100, or 200, the UPC-E code consists of the first two characters of the manufacturer code, the last three characters of the product code, followed by the third character of the manufacturer code. Under this case, The product code must be 00000 and 00999.
    2. If the manufacturer code ends with 00 but does not meet the #1 requirement, The UPC-E code consists of the first three characters of the manufacturer code, the last two characters of the product code, followed by digit 3. The product code can only contain two digits(00000 to 00099).
    3. If the manufacturer code ends in 0 but non of the above qualifies, the UPC-E consists of the first four digits manufacturer code and the last digit of the product code, followed by the digit 4. The product code in this case can only contain one digit(00000 to 00009).
    4. If the manufacturer code ends with non-zero digit, the UPC-E code consists of the manufacturer code and the last digit of the product code. In this case the product case can only be one from 00005 to 00009 because 0 to 4 has been used for the above four cases.


    Structure of an UPC-E number
    A UPC-E barcode has 6 digits with an implied number system 0. The first 5 digits are calculated based on a conversion algorithm described below. The last digit is the check digit of the original UPC-A symbol.

    UPC-E Properties
    Besides the properties to general barcode, the following property belongs to UPC-E:
    SupplementarySeparation gets or sets the space between the end of barcode and the begin of supplementary for UPC/EAN in Inches. Default is 0.2 inches.

    UPC-E Check Sum
    UPC-E check digit is calculated using standard Mod10 method.

    BarcodeComponent UPC-E Acceptable String Length
    BarcodeComponent UPC-E can accept 6, 7, 8, 11, 12, 13, 14, 16, 17 digit length.
    If the CodeData is 6 digits, a leading 0 will be added to the CodeData.
    If the CodeData is 8 digits, the first 7 digits will be used for UPC-E.

    DataMatrix Specification

    DataMatrix is a 2-D matrix code designed to pack a lot of information in a very small space. A Data Matrix symbol can store between one and 500 characters. The symbol is also scalable between a 1-mil square to a 14-inch square. That means that a Data Matrix symbol has a maximum theoretical density of 500 million characters to the inch! The practical density will, of course, be limited by the resolution of the printing and reading technology used.

    QR Code Specification

    QRCode (Quick Response Code) is a kind of 2-D (two-dimensional) symbology developed by Denso Wave and released in 1994 with the primary aim of being a symbol that is easily interpreted by scanner equipment. QR Code is capable of 360 degree (omni-directional), high speed reading. QR Code accomplishes this task through position detection patterns located at the three corners of the symbol. These position detection patterns guarantee stable high-speed reading, circumventing the negative effects of background interference.
