In the case of PDF417 each row of the barcode starts with a start pattern and ends with a stop pattern. 2. Barcodes – especially 2D barcodes like PDF417 – include other "characters" in addition to those which you enter as data. and produce a scannable barcode image. such as dBarcode. but codes printed by matrix printers must be reproduced at a large enough scale that the barcodes unit size is at least as large as the printer's pins. 1. this does NOT mean that you can type ABC. Barcodes printed by laser or quality ink-jet printer will. but are otherwise used in the same was as their 32 bit counterparts. Even when you print a barcode using a dLSoft barcode font. and others more. the user needs to be aware of a number of factors that determine whether printed barcodes can actually be scanned correctly. Picking the wrong font usually produces unreadable images! If greater control of bar thickness is needed then an image creating system. The narrow fonts should only be used if you know that a bar thickness reduction is required. The Narrow font (names ending in N) has all bars reduced by 10-16% and is supplied for users who will be creating master copy which will subsequently be printed using a wet ink technique (in which the ink spreads.e. will be required. However. in general. Many of the characters in the barcode are actually "error correction digits" designed to enable the barcode to be decoded correctly even if some parts of the image have been damaged. Just because you are using a barcode font. Consequently it is essential that you check that a printed barcode is readable using an appropriate scanner or reader. you need to ensure that the barcode has not been printed too small .it has the bar/space ratio defined at its correct value. Note that the 64 bit DLLs have names ending in 64. The font details and translation DLL calling instructions given in the following sections cover the following font kits: Aztec Font Kit DataMatrix Font Kit GS1 Databar Font Kit PDF417 Font Kit QR Code Font Kit Please see the relevant section for details of your kit. Some types of barcode use only two thicknesses of bar.names ending in W) should be suitable for most 600 and 1200 dpi laser printers .so that within the resolution of the printer a single thickness bar has been printed at the same size as a double thickness bar. render it is the barcode font. The Regular font (names ending in R) has all bars reduced by 5-8% and will probably be a better choice for 300 dpi laser printers and good quality ink-jets.2D-Barcode Fonts Introduction Barcode fonts enable you to print barcodes on high quality graphics printers that can accept fonts (i. dLSoft 2D-Barcode Fonts 2D-Barcode Fonts  1 . be printed correctly. 3. a Windows supported graphics printer or a PostScript printer that can accept downloaded fonts). Bar thickness reduction: Most dLSoft barcode fonts (apart from the GS1 Databar font) are supplied in three bar thicknesses. so making each bar thicker than in the master). others use three thicknesses. The thickness of bars and spaces in barcodes is important. The Wide font (and its variants . Aztec symbols are square and may be read at any orientation. and this can range from 1 – 32. but this time the range is 1 – 32. In Compact mode the user specifies the number of layers used to contain the symbols information – and this is restricted to the range 1 – 4. Again error correction data is used to fill otherwise unused space in the specified number of layers.DLL functions.z to represent 64 combinations of 6 bars and spaces as shown in the font table at the end of this document. to allow for ink spread during wet ink printing and the line broadening found in several printers designed for use with personal computers. The DLL will insert error correction data in the space available. This is the Level parameter in calls to the AZTDF. Security and Layers In Normal mode the user may select any percentage of the symbol to contain error checking data within the range 1 – 99%. If a value of 0 is used then the symbol will actually be produced with the default amount of error correction (which is 23% + 3 codewords). where a 1 is a bar and a 0 is a space. Appended symbols are not supported at this time. The Aztec font The Aztec font system includes TrueType and PostScript fonts for creating Aztec barcodes by printing characters to generate bars and spaces. The higher the security level the greater will be the number of layers required to contain the symbol – and hence its overall size.Aztec barcodes Aztec is a matrix symbology that supports the entire ASCII character set and offers several error checking modes. The dLSoft Aztec fonts are provided in different weights. The symbol is made up of squares which "grow" from the centre around a centre mark. The size of the symbol is characterised by the number of "layers" outside the centre mark. Aztec barcodes are made up of bars and spaces that may be 1 or more units wide. In Full range mode again the user specifies the number of layers allowed for the symbol. Font name AZTW AZTR AZTN weight full size 5% width and height reduction 10% width and height reduction 2  2D-Barcode Fonts dLSoft 2D-Barcode Fonts . The individual characters are made up of six square in a pattern 3 high by 2 wide. punctuation and new lines/paragraphs reduce this value. The dLSoft Aztec fonts uses the ASCII characters 0 (zero) .) Runes are special Aztec symbols that consist of a single layer and have no security options. with each square representing a bit of a 6 bit binary value. In Full range mode the maximum capacity of Aztec Code symbols is approximately as follows: Digits only – maximum capacity 3800 digits Alphanumeric text – maximum capacity 3000 characters* Byte values – maximum capacity 1900 bytes (*Note that capital letters.

Consequently only relatively small Aztec barcodes (100 characters maximum) may be generated using this UFL. eg. and each line of the barcode returned using getBarcodeString(i). The dFontAZ Java class The dFontAZ Java class may be used to return strings that contain rows of characters that.drawString(az1. for (i=0.x.DLL) is installed into the Windows\System32 directory.

The Databar Fonts The Databar font system includes TrueType, OpenType and PostScript fonts for creating Databar barcodes by printing characters to generate bars and spaces. Databar barcodes are made up of bars and spaces that may be 1 or more units wide. The dL Databar fonts use the following ASCII characters: A – P and a – f for the Databar modes Omnidirectional and Expanded (including the stacked variants) 0, 1 for the Truncated mode 2, 3 for the Limited mode 4 – 9 for the Stacked mode. The minimum height of the bars in relation to the width of the thinnest bar is different for different modes, so for a given point size the width of the characters is different. The height;width ratio for the characters is: A – P and a-f: ratio = 1000 : 27 0, 1: ratio = 1000 : 77 2, 3: ratio = 1000 : 100 4 – 9 : ratio = 1000 : 143 22  2D-Barcode Fonts dLSoft 2D-Barcode Fonts The DBARDF DLL To convert a string of characters into the bars and spaces required for the barcode requires converting the character string into another string – made up of only the characters present in the dL Databar font.

The efficiency of data encoding has been increased with the use of only one position detection pattern.z to represent 64 combinations of 6 bars and spaces as shown in the font table at the end of this document.

The PDF font The PDF417 font system includes TrueType and PostScript fonts for creating PDF barcodes by printing characters to generate bars and spaces. where a 1 is a bar and a 0 is a space. PDF barcodes are made up of bars and spaces that may be 1 to 8 units wide. The PDFDF DLL To convert a string of characters into the bars and spaces required for the barcode requires converting the character string into another string – made up of only the characters present in the PDF font.

This permits an array of bytes to be used as data by constructing the Caption string from a know length byte array using String(byte[] bytes). or setParam(“CODETYPE”. For example. Note: the setSerial() method must be used to pass the developer’s serial number to the class BEFORE any barcodes are generated. except for dFontPDF.Errorcode) Common Java class features Each dFontXX java classes provide methods for determining the barcode features supported and for setting barcode characteristics and retrieving the barcode strings.

The array index is the ModeType. setting this property to true results in the interchange of foreground and background colours for the barcode elements. Do not set this property. ModeType Type: int Default: 0 Most 2D barcodes have several different modes (eg.
