Printing Support
The EaseSoft Barcode DLL produces high resolution(2400DPI) Enhanced Metafile (vector) graphics that are completely device independent, fully scalable, and will print to the highest resolution of any printer supported by Windows.

Developer Support
The EaseSoft Barcode DLL was created in Visual C++ using ATL, there are no additional runtime dependencies (i.e. MFC Class Libraries or Visual Basic Runtimes).When you distribute your application you only need to include one binary component EaseBarDLL.dll.

USE TILDE CODE TO INPUT CONTROL CHARACTERS

  1. You can input any ASCII character using Tilde code with the format ~ddd, d represents one digit, ddd is the ASCII value of the character. For example, if you enter the text “1234~013~010”, then it will converts to “1234CRLF”, CR is carriage return character and LF is new line character.
  2. Also you can use the format ~X ( X is any upper case alpha character) to insert control codes (characters with ASCII value 0 to 26). For example, ~@ = NUL, ~A= ASCII 1,~G = BEL (ASCII 7), ~M = ASCII 13 (carriage return).

SYMBOLOGY SPECIFIC NOTES

  1. UPC A, UPC E, EAN 8 ,EAN 13 AND BOOKLAND
    They only can be encoded numeric data, and you can add 2 digits or 5 digits supplement to the end of the string with separator ‘,’ ,For example, “12345678901,12345”. UPC A must encode 11 digits, UPC E must encode 6 digits,EAN 8 must encode 7 digits, EAN 13 must encode 12 digits,BOOKLAND must encode 9 digits of ISBN number.
  2. Code 128
    Code 128 will automatically analyse the string to choose a better character set to encode the shortest barcode. The FNC definition in code 128 is as following: FNC1 is ASCII 200, FNC2 is ASCII 201, FNC3 is ASCII 202, FNC4 is ASCII 203.
  3. UCC/EAN-128 input data format:
    (AI)XXXX(AI)XXXX, AI is application identifier number, XXXX is data after AI. For example,(11)040901 means production date Sep 01,2004.
  4. Codabar Start and Stop character:
    It can be A,B,C or D. If you don’t input one of them to be as your start and stop character, the default value “A” will be added to the encoding string.
  5. Code 11:
    Code 11 only can encode numeric data(0 to 9),the dash symbol(-). It is also known as USD-8
  6. Code 93:
    Code 93 is a continuous, variable-length symbology,it can encode the full ASCII character set. Code 93 is similar to Code 39. It encodes 47 characters.

PDF417 PROPERTIES:

  • PDFSecurityLevel: The PDF417 SecurityLevel property allows you to select a PDF417 error correction level from 0 to 9 (default = 9 for automatic). PDF417 uses Reed Solomon error correction instead of check digits. This error correction allows the symbol to withstand some damage without causing loss of data. AIM standards recommend a minimum error correction level of 2. The error correction level depends on the amount of data that needs to be encoded, the size, and the amount of symbol damage that could occur.
  • PDFMaxCols: The PDFMaxCols property specifies the maximum number of codeword columns in a PDF symbol. The default value for PDFMaxCols is 0, meaning that program automatically picks the number of columns. It can be set to a value range from 1 to 30.
  • PDFMaxRows: PDFMaxRows properties allow you to set the target number of rows. The default value for PDFMaxRows is 0, meaning that program automatically picks the number of rows. The valid range for this property is 3 to 90.
  • PDFModuleHeight: PDFModuleHeight sets a value for the height of the smallest modules in the PDF417 barcode generated.The recommended value for the Module Height is approximately three times the value for the PDFModuleWidth property. You can set this property to any values greater than 10 mils. The valid range for PDFModuleHeight is between 1 to 100. The default value is 30.
  • PDFModuleWidth: PDFModuleWidth sets a value for the width of the smallest modules in the PDF417 barcodes generated.The recommended value for the Module Width is between 10 and 30 mils. To achieve the best read rate, we recommend that you set to a value which is integral times of the pixels width of the target device (the width of a pixel in the display screen is 13.88 mils and the one in the laser printer is 3.33 mils). The default value is 10.
  • PDFAspectRatio:The PDFAspectRatio determines the overall shape of the PDF417 symbol and is defined as the overall height to width ratio. Higher values for the Aspect Ratio (greater than 1) produce tall, thin PDF417 bar codes and small values (greater than zero and less than 1) produce short, wide bar codes. A value of 1 should produce approximately square bar codes. The default value for this property is 1.
  • PDFTruncatedSymbol:A truncated PDF417 symbol is more area efficient than normal PDF417. By selecting this option, the right hand side of the symbol is removed or “truncated”. This option should only be used in clean environments, since it is less immune to damage.

DATAMATRIX PROPERTIES:

  • EncodationMode: the encoding mode that compresses information in the symbol; Default value is E_AUTO, it will automatically to select the best encoding mode to compress the message.
    • E_ASCII: it is used to encode data that mainly contains ASCII characters (0-127). It encodes one alphanumeric or two numeric characters per byte.
    • E_C40: it is used to encode data that mainly contains numeric and upper case characters. C40 encodes three alphanumeric data characters into two bytes.
    • E_TEXT: it is used to encode data that mainly contains numeric and lowercase characters. TEXT encodes three alphanumeric data characters into two bytes.
    • E_BASE256: it is used to encode bytes of data and 8 bit values.
  • DataMatrixSize: sets the 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.
  • DataMatrixModuleSize: PDFModuleWidth sets a value for the width of the smallest modules in the PDF417 barcodes generated.The recommended value for the Module Width is between 10 and 30 mils. To achieve the best read rate, we recommend that you set to a value which is integral times of the pixels width of the target device (the width of a pixel in the display screen is 13.88 mils and the one in the laser printer is 3.33 mils). The default value is 10.
