Linear Properties:
- DataToEncode - This is the data that is to be encoded in the barcode. If connecting the control to a control source, then the source will override this field.
- SymbologyID - This is the type of barcode to be used. The default is Code 128. For more information on barcode types, visit IDAutomation's barcoding for beginners site.
- BarHeightCM - The height of the barcode in cm. Default is 1 cm.
- LeftMarginCM - The space of the left margin in cm.
- XDimensionCM - Width in centimeters of the narrow bars. The default is 0.03 cm which is about .012" or 12 mils. This value may need to be increased if the scanner cannot read barcodes with small X dimensions. When working with a high quality scanner, this value can be decreased to obtain a higher density barcode.
- XDimensionMILS - The width in mils (1/1000 of an inch) of the narrow bars.
- ApplyTilde - This option is only available when the symbology
is Code 128, the character set is AUTO and ApplyTilde is enabled. Default
is off.
When ApplyTilde is enabled, the following options are available:
- Encode an ASCII character: The format ~ddd may be used to specify the ASCII code of the character to be encoded. For example, if entering the following text in the Data field: 66~029777 it will actually be encoding 666GS77 Where GS is a delimiter ASCII 29 character. Other commonly used ASCII codes are ~009 for a tab and ~013 which is a return function. For encoding other functions, please refer to the ASCII chart.
- Encoding UCC/EAN-128: To encode
alpha-numeric UCC/EAN128, the character must be set to "AUTO" for
automatic. Then, ASCII 202 or character Ê is entered as the FNC1
before each AI and the required start C is included automatically.
For example, the UCC number of (8100)712345(21)12WH5678 should be
entered as: Ê8100712345Ê2112WH5678. In most cases,
the AI's will be properly represented in the human readable text.
If the parenthesis is not around the correct number for the AI,
enter the following extended ASCII character as the FNC1 for the
correct number of digits in the AI:
ASCII 212 = 2 digits
ASCII 213 = 3 digits
ASCII 214 = 4 digits
ASCII 215 = 5 digits
ASCII 216 = 6 digits
ASCII 217 = 7 digits
For example, to encode (1277)56, enter Ö127756.
For more information, please refer to the UCC/EAN 128 section of the Code 128 FAQ - Create a Mod 10 Check digit: to Create a Mod 10 check digit for xx number of characters add the following to the DataToEncode: ~mnn (where nn is a 2 digit number representing the number of characters preceding the tilde in which to base the Mod 10 calculation). The additional MOD 10 check digit is commonly used in UCC or EAN barcode types. For example, setting the DataToEncode property to Ê4021234567890123456~m16, will cause a mod 10 check digit to be created based on all 16 characters before the tilde. The human readable text and scanned data will display as (402)12345678901234566. The final 6 is the mod 10 check digit and replaces ~m16.
- FNC2: When necessary, the FNC2 character may be inserted into the DataToEncode string by using ASCII 197. For example; Å8012349091. IDAutomation's SC5USB Scanner can be programmed to hold the barcode starting with the FNC2 in memory and only transmit it to the computer after scanning a barcode containing the FNC1.
- BMPPicture - Use the BMPPicture method to obtain an image that can be sent to the clipboard. See example
- CaptionAbove - Text that can be placed above the barcode.
- CaptionBelow - Text that can be placed below the barcode.
- CaptionTopAlignment - The left, right, or center alignment, in the drawing area, of the text above the barcode.
- CaptionBottomAlignment - The left, right, or center alignment, in the drawing area, of the text below the barcode.
- CaptionBottomColor - The color of the font of the caption below the barcode.
- CaptionTopColor - The color of the font of the caption above the barcode.
- CaptionBottomSpace - The distance, in cm, between the human readable text below the barcode and the caption below the barcode
- CaptionFont - The font of the caption above and below the barcode
- CaptionTopSpace - The distance, in cm, between the bottom of the caption above the barcode and the top of the barcode
- CheckCharacter - Automatically adds the check digit to the barcode. The check digit is required for all symbologies except Code 39, Industrial 2 of 5 and Codabar. When using symbologies that do not require the check digit, the check digit may be disabled.
- CheckCharacterInText - Automatically adds the check digit that is encoded in the barcode to the human readable text that is displayed. This is not applicable to Code 128.
- CodabarStartCharacter - The start character for CODABAR. Valid values are "A", "B", "C" or "D".
- CodabarStopCharacter - The stop character for CODABAR. Valid values are "A", "B", "C" or "D".
- Code128Set - The set of characters to be used in code128. Valid values are: AUTO, A, B or C. The default and recommended selection is AUTO. For more information on Code 128, review the Code 128 FAQ.
- BackColor - The background color of the barcode.
- Font - The font of the text in the barcode.
To change the font in code, use the following syntax for VB .NET:
Barcode1.Font = New Font(New FontFamily("Arial"), 14)
To only the point size in code, use the following syntax for VB.NET:
Barcode1.Font = New Font(Barcode1.Font.FontFamily, 14) - ForeColor - The color of the foreground text and bars in the barcode.
- FitControlToBarcode - If true will automatically size the control canvas to fit the barcode at design or runtime.
- NarrowToWideRatio - This is the wide to narrow ratio of symbologies that only contain narrow and wide bars such as Code 39, Interleaved 2 of 5 and MSI. Usually, this value is between 2 and 3. The default value is 2.
- Resolution - The source that is used to determine the resolution the image is drawn to, which creates a more accurate barcode. Default is printer. If custom is selected, the number residing in the ResolutionCustomDPI property will determine the resolution.
- ShowText - If this value is yes or true, the human readable text will be displayed with the barcode.
- ShowTextLocation - The human-readable text can be placed above or below the barcode. Default is below.
- TextMarginCM - The distance between the lower portion of the barcode and the text.
- TopMarginCM - The top margin in cm.
- UPCESystem - The encoding system to be used for UPC-E, valid values are 0 and 1.
- Read the
PDF417 FAQ for
information about this symbology.
These properties are available only in the 2D version for idautomation.cfpdf417.dll. - ApplyTilde - If set to "true", use the format ~ddd to specify the ASCII code of the character to be encoded. Default is "true". Commonly used ASCII codes are ~009 for a tab and ~013 which is a return function.
- PDFColumns - Controls the width and height by increasing the number of data columns in the PDF-417 barcode. The default is 0 and the maximum is 30. When this is left at 0, the control will automatically adjust this setting.
- PDFErrorCorrectionLevel - The Reed Solomon error correction level placed in the symbol. More error correction creates a larger symbol that can withstand more damage. Default = 0 for automatic selection.
- PDFMode - The default, (binary mode) encodes bytes of data and text mode encodes all characters on the US keyboard plus returns and tabs. If the user is encoding only text, text mode can usually reduce the symbol size.
- PDFRows - The number of minimum rows. If this setting is left at 0 the control will automatically adjust this setting. IDAutomation recommends leaving this set to 0 because the number of rows should be automatically generated.
- XtoYRatio - The X multiple height of individual cells; default=3.
- Read the
Data Matrix FAQ
for information about this symbology.
These properties are available only in the 2D version for idautomation.cfdatamatrix.dll. - EncodingMode - The encoding mode that compresses information
in the symbol; valid values are, E_ASCII, E_C40, E_TEXT or E_BASE256
(default).
- ASCII: It is used to encode data that mainly contains ASCII characters (0-127). It encodes one alphanumeric or two numeric characters per byte.
- C40: It is used to encode data that mainly contains numeric and upper case characters. C40 encodes three alphanumeric data characters into two bytes.
- TEXT: It is used to encode data that mainly contains numeric and lowercase characters. TEXT encodes three alphanumeric data characters into two bytes.
- BASE256: It is used to encode bytes of data and 8 bit values.
- More information about the modes is documented here.
- PreferredFormat (DM_FORMAT): Sets the preferred format represented by a number; valid values are from 0 (10X10) to 23 (144X144) and from 24 (8X18) to 29 (16X48); This will be automatically determined if the size of the symbol chosen is too small. More about this is documented here.
- ProcessTilde - If true ("Y") the tilde (~) will be processed.
For example, use ~d032 for a space character, ~d009 for
a tab and ~d013 to encode a return.
- ~dNNN: Represents the ASCII character encoded by the 3 digits NNN. For example, ~d065 represents the character 'A'.
- ~1: Represents the character FNC1. When FNC1 appears in the first position (or in the fifth position of the first symbol of a Structured Append), it will indicate that the data conforms to the UCC/EAN Application Identifier standard format.
- More about the tilde formatting is documented here.
