2D-Barcode Fonts

Introduction Barcode fonts enable you to print barcodes on high quality graphics printers that can accept fonts (i.e. a Windows

supported graphics printer or a PostScript printer that can accept downloaded fonts). However, the user needs to be

aware of a number of factors that determine whether printed barcodes can actually be scanned correctly.

1. Just because you are using a barcode font, this does NOT mean that you can type ABC, render it is the barcode font,

and produce a scannable barcode image. Barcodes – especially 2D barcodes like PDF417 – include other "characters" in

addition to those which you enter as data. In the case of PDF417 each row of the barcode starts with a start pattern and

ends with a stop pattern. 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.

2. The thickness of bars and spaces in barcodes is important. Some types of barcode use only two thicknesses of bar,

others use three thicknesses, and others more. Even when you print a barcode using a dLSoft barcode font, you need to

ensure that the barcode has not been printed too small - so that within the resolution of the printer a single thickness bar

has been printed at the same size as a double thickness bar. Consequently it is essential that you check that a printed

barcode is readable using an appropriate scanner or reader.

Barcodes printed by laser or quality ink-jet printer will, in general, be printed correctly, 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.

3. Bar thickness reduction: Most dLSoft barcode fonts (apart from the GS1 Databar font) are supplied in three bar

thicknesses. The Wide font (and its variants - names ending in W) should be suitable for most 600 and 1200 dpi laser

printers - it has the bar/space ratio defined at its correct value. 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. 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, so making each bar thicker than in the

master). The narrow fonts should only be used if you know that a bar thickness reduction is required. Picking the wrong

font usually produces unreadable images! If greater control of bar thickness is needed then an image creating system,

such as dBarcode, will be required.

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. Note that the 64 bit DLLs have names ending in 64, but are

otherwise used in the same was as their 32 bit counterparts.

2 2D-Barcode Fonts dLSoft 2D-Barcode Fonts

Installing additional fonts

While most of the commonly used fonts are installed automatically, you may wish to install additional fonts, including

reduced or narrow fonts, or Postcript variants.

Note that some additional fonts are supplied in compressed folders. Please copy the contents of a compressed folder to a

normal temporary folder before attempting to install the fonts. The compressed fonts folder will be located under your

chosen samples folder. [The additional fonts in the Databar Font Kit are not compressed]

Windows XP/2003/Vista

Open the Font Applet in the Windows Control Panel

From the Fonts window menu bar choose "Install New Font".

The Add fonts dialog appears.

Use the Drives and directory list boxes to select the installation directory containing your fonts. (If you are transferring

the fonts to another computer obviously copy them from the original installation directory to some medium that can be

accessed by the the new machine.)

Ensure that the "Copy Fonts to Fonts folder" check box is checked.

Select the fonts you wish to install from the list presented, and then push the OK button.

Your fonts are now ready for use.

Windows 7

For TrueType/OpenType fonts:

Open the Control Panel Choose Appearance and Personalisation.

Click on Fonts to open the Fonts windows

Now drag the fonts you require to the Fonts Windows

For PostScript fonts double-click on the .PFM file. The font viewer opens. Click on the Install button at the top of the

viewer.

Windows 8/10

Open File Explorer (Windows Key + X, select File Explorer from pop-up menu).

Click on Fonts to open the Fonts windows

Now drag the fonts you require to the Fonts Windows

For PostScript fonts double-click on the .PFM file. The font viewer opens. Click on the Install button at the top of the

viewer.

Your fonts are now ready for use, and the temporary folder may be deleted.

Aztec barcodes Aztec is a matrix symbology that supports the entire ASCII character set and offers several error checking modes. Aztec

symbols are square and may be read at any orientation.


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, and this can range from 1 – 32.

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%. This is the Level parameter in calls to the AZTDF.DLL functions. 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). The higher the security

level the greater will be the number of layers required to contain the symbol – and hence its overall size.

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. The DLL will insert error correction data in the space available.

In Full range mode again the user specifies the number of layers allowed for the symbol, but this time the range is 1 – 32.

Again error correction data is used to fill otherwise unused space in the specified number of layers.

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, punctuation and new lines/paragraphs reduce this value.)

Runes are special Aztec symbols that consist of a single layer and have no security options.

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. Aztec barcodes are made up of bars and spaces that may be 1 or more units wide. The dLSoft

Aztec fonts uses the ASCII characters 0 (zero) - z to represent 64 combinations of 6 bars and spaces as shown in the font

table at the end of this document, where a 1 is a bar and a 0 is a space. The individual characters are made up of six

square in a pattern 3 high by 2 wide, with each square representing a bit of a 6 bit binary value.

The dLSoft Aztec fonts are provided in different weights, to allow for ink spread during wet ink printing and the line

broadening found in several printers designed for use with personal computers.

Font name weight

AZTW full size

AZTR 5% width and height reduction

AZTN 10% width and height reduction

Users should determine which font weight is suitable for their printer by testing each font weight. It should be noted that

if gaps between the font squares are clearly visible then the barcode will not scan correctly.


The AZTDF 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 0 - z characters present in the Aztec font.

The following DLLs will perform the conversion:

AZTDF.DLL – 32 bit ANSI version

AZTDFU.DLL – 32 bit Unicode version

AZTDF64.DLL – 64 bit ANSI version

AZTDF64U.DLL – 64 bit Unicode version

The DLLs provide three function calls which can either return the required string, copy it to the clipboard, or save it to a

named disk file. These functions may be called from Visual Basic (including Visual Basic for Applications in Microsoft

Office), Visual C++, Visual Foxpro, Delphi, C++ Builder, and in fact virtually every language that can make DLL calls.

The functions are called with parameters that specify the options available for the barcode:

szIn – is a pointer to a string containing the bytes used as data to create the barcode. While passed as a text string, the

string can contain non-text bytes (including ASCII 0) provided that the length parameter (n) is used to specify the length

of the data. If n is 0, then the string is assumed to be a null-terminated string.

n – a pointer to an integer which is either 0 or specified the length of the data in szIn.

flags – may be used in the Unicode versions to force encoding the data as Unicode by setting bit 7 to 1. (ie. 128).

Otherwise this value should be 0.

level – a pointer to an integer specifying the security level of the barcode generated. Allowed values for Aztec codes

depend on the mode, and are 0-99 for Normal mode, 1-4 for Compact mode, and 1-32 for Full range mode (the value is

ignored for Runes). Note that for Compact and Full range the security level is actually the required number of Aztec

layers in the symbol.

mode – a pointer to an integer specifying the type of Aztec barcode created. The allowed values are shown below.

mode parameter Barcode type

0 Normal

1 Compact

2 Full range

3 Rune

For most applications a mode of 0 is recommended, along with a level of 0 which provides the default value of 23% + 3

codewords.

Aztdf Function calls

The available function calls are:

BarsOutAz()

Creates the barcode in the device context hdc at coordinates xin,yin (in MM_TEXT units) using the properties specified.

The Aztec control

The AZTOCX control is an Active-X control which simplifies the use of barcodes in Active-X containers such as Visual

Basic and MS Access.

The AZTOCX control may be placed on a form in most applications which support Active-X controls, such as Visual

Basic, Microsoft Access, etc. The Aztec barcode properties may be specified through a series of Properties, either via

programming, or by setting the properties in the control’s property pages.

Placing the Aztec control on a form

Visual Basic 6

To add the control to a Visual Basic project select Components from the Project menu, then select AZTOCX Active-X

Control module from the list of controls displayed and push the OK button. The module’s icon will appear in the

Toolbox. The control may then be added to a form by clicking on the control’s icon and then drawing a rectangle for the

control on the required form.

If the control is to be visible then the area allowed should be large enough to hold the largest barcode required. If the

control is to be hidden, then the size is irrelevant.

Once added to a form, selection of the control will show the available properties in Visual Basic’s properties window.

VB.NET and C#

The control may be added to the Visual Studio Toolbox by right clicking on the Toolbox and selecting Add/Remove

Items (or Choose Items for VS 2005 or later) from the pop-up menu displayed, then checking the control in the list

presented. The control will then appear as an icon on the Toolbox.


Access

To add the control to an Access Form or Report, open the form or report in Design view and ensure that the Toolbox is

visible (its on the View menu). Select the “More controls” icon on the Toolbox and then select the AZTOCX Active-X

Control module from the list of controls displayed. Draw a rectangle for the control on the from or report.

Once added to a form or report, selection of the control will show the available properties in Access’s properties

window. The font should be set by right-clicking on the control and choosing the Aztocx control properties from the

displayed menu.

Aztec Property pages

The control also has its own property pages which may be accessed by right-clicking on the control and selecting

Properties from the displayed menu.

General Property page

This permits the setting of the barcode’s mode and security level properties, and allows the control to be set to resize

itself each time it is drawn

Data Property page

The edit box on this page shows the data currently being used to generate the barcode image. It is useful only for

displayable characters. To provide data which includes non-printable characters the Caption property should be set via

programming.

Font Property page

This page allows the user to select the barcode font and font size used to generate the barcode.

Colors Property page

This page allows the user to specify the foreground (the bars) and background color of the barcode generated. In general

barcodes should be produced with a black foreground and a white background color.

Aztec Control Properties

The control has the following properties which may be set in the property pages or programmatically with Visual Basic.

Caption: (BSTR) the data which will be converted into a barcode

AutoSize: (Boolean) if non-zero causes the control to resize itself to contain the barcode.

BackColor: (Colorref) the background color

CapLength: (integer) normally 0, in which case the length of the data string in the Caption property is determined

automatically. If non-zero it is taken to be the number of characters in the Caption property to be used as data.

Errorcode: (integer) a non-zero value is returned if the data supplied in the Caption property can be converted into a

valid barcode.

Flags: (integer) if bit 7 is set (ie 128) the data is encoded as Unicode, otherwise as ANSI.

Font: (Font) the font in which the Output characters will be displayed

ForeColor: (Colorref) the color of the bars in the barcode

Level: (integer) the security level for the generated barcode (see the DLL above for a description)


Mode: (integer) the mode used to generate the barcode (see the DLL above for a description)

Output: (CString) the characters which when displayed in the correct font, produce the barcode. Note that this string

may be much larger than the Caption string.

In addition the control supports the normal Active-X properties, such as Visible, Height, Width, etc.

Aztec .NET Managed Component

Developer versions require the developer’s serial number to be passed to the component using the Serial property before

the Barcode() method is called. The Serial property should be set to the serial number provided for your product, e.g.

Aztnet1.Serial="12345" for VB

aztnet1.Serial="12345"; for C#

Use of an incorrect serial number will result in randomly scrambled symbols.

Main properties and methods are shown below; others are listed in the Common .NET component features section

Aztec.NET Properties

AzFlag

Type: bool

Default: false

Sets the Aztec flag on or off.

AzMenu

Type: bool

Default: false

Sets the Menu flag on or off.

AzRvideo

Type: bool

Default: false

Sets the Reverse Video flag on or off.

ByteNumber

Type: integer

Default: 0

Allowed values: 0 – barcode byte capacity


When ByteValue is greater than 0 the Caption string (which is a Unicode string) is unpacked into 8-bit ASCII characters

before the data is used to generate the barcode.

Caption

Type: string

Default: "0123456789"

Allowed values: Any text string.

Note: only text strings recognised as valid barcodes will result in a barcode picture. An Illegal character in the text string

will cause an Error value to be set.

CodeType

Type: bCode enumeration member

Default: bCode.AZT

Allowed values: bCode.AZT

CodeTypeValue

Type: integer

Default: 0

Allowed values: 0

The barcode type can be set using either the CodeType property or the CodeTypeValue property.

Flag

Type: Boolean

Default: false

Allowed values: true or false

When Flag is set to true the Caption data is treated as a Unicode string and converted to a byte stream. When Flag is

false the Caption data is handled as described for the ByteNumber property.

StartMode

Type: integer

Default: 0

Allowed values: See 2D Barcodes section for allowed mode setting for specific barcode types.

SecurityLevel

Type: integer

Default: 0

Allowed values: See 2D Barcodes section for allowed security level setting for specific barcode types and modes.


Aztec.NET Methods

Barcode()

Return Type: string

This method causes a barcode to be created as a sequence of character that, when displayed in the AZTx font will form

the barcode symbol.

Note that the barcode symbol is determined only when this method is called, so the information properties are not set

until this method has been called.

BarDecode(string bc)

Return Type: string

This method returns a string decoded from the barcode passed as parameter bc. Note that bc is a barcode created by the

Barcode() method.

DataMatrix barcodes DataMatrix is a two-dimensional matrix symbology that is made up of square modules arranged within a finder pattern.

DataMatrix symbols may be square or rectangular.

DataMatrix symbols may include a user-select amount of error-correction, set by the security parameter. For Square

symbols the value may range from 0 – 24. For Rectangular symbols the value may range from 0 - 6.

DataMatrix symbols can encode the entire ASCII character set and uses multiple encoding modes, which are, in order of

efficiency:

Double digits – maximum capacity 3100 digits



*Note that capital letters, punctuation and new lines/paragraphs reduce this value.

dLSoft 2D barcode products support only ECC200 symbols – the older ECC140 and below are not supported. Also at

this time ECI and Appended symbols are not supported.

The size of a Datamatrix barcode is normally determined by its content and security level, although a size may be

specified by setting the number of columns in the symbol; the only other control allowed is whether the barcode is

square or rectangular.

The DeutschePost variant of Datamatrix may be created generally by checking the DeutschePost option in dialogs, or

setting the DL_DEUTSCHEPOST flag (bit 9, or value 512) in the flags parameter of the function calls.


PostMatrix

The Deutsche Post PostMatrix code is a Datamatrix symbol preceeded by two vertical lines before the vertical alignment

edge of the Datamatrix symbol.

PostMatrix

PostMatrix codes mat be produced by checking the Deutsche Post bars option in the Active-X properties dialog, or

setting the DL_POSTMATRIX flag (bit 6, or value 64) in the flags parameter of the function calls.

DataMatrix font

The DataMatrix font system includes TrueType and PostScript fonts for creating DataMatrix barcodes by printing

characters to generate bars and spaces. DataMatrix barcodes are made up of bars and spaces that may be 1 or more units

wide. The dLSoft DataMatrix fonts uses the ASCII characters 0 (zero) - z to represent 64 combinations of 6 bars and

spaces as shown in the font table at the end of this document, where a 1 is a bar and a 0 is a space. The individual

characters are made up of six square in a pattern 3 high by 2 wide, with each square representing a bit of a 6 bit binary

value.

The dLSoft DataMatrix fonts are provided in different weights, to allow for ink spread during wet ink printing and the

line broadening found in several printers designed for use with personal computers.

Note that specific functions use the code parameter to enable DMRE barcodes to be created. Older functions (without a

code parameter) are included for backward compatibility.

flags – an integer with specific bits:

bit 1 (ie. Flags value 2) may be set to 1 to force GS1 encoding (and automatic handling of AIs)

bit 6 (ie 64) when set a PostMatrix symbol is generated. Otherwise this bit should be 0

bit 7. (ie. 128) in the Unicode versions the data may be encoded as Unicode by setting bit 7 to 1.

bit 9 (ie 512) may be set to 1 to create a DeutschePost symbol in Base256 encoding mode

mode specifies the encoding and shape of the barcode:

Mode value mode

0 Automatic – Square

1 Automatic – Rectangular

2 ASCII encoding – Square

9 X12 encoding – Rectangular

10 EDIFACT encoding – Square

11 EDIFACT encoding – Rectangular

12 Base 256 encoding – Square

13 Base 256 encoding – Rectangular

security is the security level and szOut is a pointer to a string which will receive the characters to be rendered in the

DataMatrix (AZT) font.

The security level has allowed values of 0 – 24 for square symbols, or 0 – 6 for rectangular symbols. (A negative security

level may be used to specify the number of columns in the symbol in those calls which do not include a columns

parameter. This feature is included for backward compatability only. New applications should use the calls that do

contain a columns parameter.).

Columns is the number of elements across the symbol. If a value of 0 is used then the symbol is created using the

smallest number of elements possible. The value can be 10 – 144 for square symbols, or 18 – 48 for rectangular symbols.

Barcode() method.


GS1 Databar barcodes The GS1 DataBar symbology - formerly known as EAN.UCC Reduced Space Symbology (RSS) - is a family containing

three linear symbologies and three stacked variants, known as GS1-DataBar barcodes. GS1-DataBar-14 encodes the full

14 digit GS1/EAN/UCC item identification in a linear symbol that can be scanned in any direction. GS1-DataBar

Limited encodes item identification suitable for use on small items, but not for use at point-of-sale.

GS1-DataBar -Expanded encodes the 14 digit GS1/EAN/UCC item identification plus supplementary AI elements.

GS1-DataBar -14 Stacked is a variant which is stacked in two rows, either as a truncated version used for small item

marking,

or as an omni-directional version designed to be read by omnidirectional scanners.

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

QR Code barcodes QR Code is a matrix symbology consisting of a square array of modules with a finder pattern located at three corners. A

wide range of symbol sizes is supported along with four levels of error correction, and the symbology is noted for its

high data density.

The dLSoft libraries support QR Code Version 2 in Numeric, Alphanumeric and Byte modes. (Kanji mode is supported

by some but not all components).

The maximum data capacity of the symbols (at Level 0 error correction) are:

Numeric data 7089 digits

Alphanumeric data 4296 characters

Byte data 2953 bytes

Note that Alphanumeric includes digits and uppercase letters, the space and the $ % * + - . / : characters only.

The Reed-Solomon error correction allows the following recovery of damaged codewords:

Level 0: 7%

Level 1: 15%

Level 2: 25%

Level 3: 30%

Micro QR Code

The dLSoft Libraries also support Micro QR Code. Micro QR Code is a very small QR Code that fits applications that

require a smaller space and use smaller amounts of data, such as ID of printed circuit boards and electronics parts, etc.

The efficiency of data encoding has been increased with the use of only one position detection pattern.

The capacity of Micro QR Code symbols at the lowest error correction level is:

Numeric data 35 digits

Alphanumeric data 21 characters

Byte data 15 bytes

The QR Code Fonts

The QR font system includes TrueType and PostScript fonts for creating QR barcodes by printing characters to generate

bars and spaces. QR barcodes are made up of bars and spaces that may be 1 or more units wide. The dLSoft QR fonts

uses the ASCII characters 0 (zero) - z to represent 64 combinations of 6 bars and spaces as shown in the font table at the

end of this document, where a 1 is a bar and a 0 is a space. The individual characters are made up of six square in a

pattern 3 high by 2 wide, with each square representing a bit of a 6 bit binary value.


The dLSoft QR fonts are provided in different weights, to allow for ink spread during wet ink printing and the line

Barcode() method.

PDF417 barcodes PDF417 (Portable Data File 417) is a stacked barcode symbology capable of encoding over a kilobyte of data in a

symbol.

PDF417 may include extensive error-correction enabling data to be recovered from a symbol that has been damaged or

corrupted.

There are 900 different patterns (codewords) which may be incorporated into a PDF417 symbol, and several modes

available for encoding.

Encoding Modes

EXC (Extended Alphanumeric Compaction mode) - allows encoding of all printable ASCII characters into about 2

characters per codeword. Within the EXC mode there are several submodes:

Binary/ASCII Plus mode - allows encoding of 256 international characters including the full ASCII set plus any 8-bit

value in the range 0 - 255. This mode allows encoding approximately 1.2 bytes per codeword and so is considerable less

efficient than EXC mode.

Numeric mode - allows encoding of a string of digits with a density of approximately 2.95 digits per codeword.

Recommended where more than 13 digits are to be encoded. Numeric mode symbols may not contain non-numeric

characters.

The maximum capacity of PDF417 symbols is approximately as follows:

Numeric mode – maximum capacity 2700 digits*



*Note that capital letters, punctuation, mode shifts and new lines/paragraphs reduce these value.


Security level

One of PDF417’s most valuable features is its ability to allow correction of errors. This ability is provided by the

inclusion of additional codewords within the symbol, so that the data codewords may be reconstructed even if some are

defaced or misread.

The number of damaged codewords (Nmax) which may be recovered depends on the security level (which in turn

determines the number of additional characters included in the symbol)

Security level Nmax

0 0

1 2

2 6

3 14

4 30

5 62

6 126

7 154

8 510

Aspect ratio

PDF417 symbols may be reproduced with different number of codewords per row, and therefore in several different

height to width ratios.

The user may select either target ratio (as the height to width ratio) or the required number of codewords per row. In

general tall, thin barcodes read more reliably than short, wide symbols, although there may be restrictions applied by the

type of barcode scanner employed.


Micro PDF 417

MicroPDF417 is a multi-row symbology based on PDF417 designed for applications requiring a greater area efficiency

but lower data capacity than PDF417. A specific and limited set of symbol sizes is available, each size including a fixed

level of error correction.

MicroPDF417 provides for three encoding modes: Text, Byte and Numeric compaction. Text is for general text,

Numeric for encoding data consisting only of digits, and Byte to allow for the first 127 ASCII characters but with a

reduced level of efficiency. Four symbol widths are permitted, each specifying the number of data columns (1 – 4).

Within each symbol width a variable number of rows provide for a maximum data capacity of:

Text compaction mode 0: 250 characters (2 data characters per codeword)

Byte compaction mode 1: 150 characters (1.2 data characters per codeword)

Numeric compaction mode 2: 366 characters (2.93 data characters per codeword)

The Level parameter for MicroPDF barcodes set the number of data columns within the barcode, which may be 1 – 4.

The industry standard Macro sequences [)>{RS}05{GS} and [)>{RS}06{GS} are supported (where {RS} represents

ASCII 30 and {GS} is ASCII 29).

The following character translations are made when the value of the mode parameter is increase by 8.


String converted to

{ET} ASCII 4

{FS} ASCII 28

{GS} ASCII 29

{RS} ASCII 30


The PDF font

The PDF417 font system includes TrueType and PostScript fonts for creating PDF barcodes by printing characters to

generate bars and spaces. PDF barcodes are made up of bars and spaces that may be 1 to 8 units wide. The dLSoft PDF

fonts uses the characters 0 (zero) - z to represent 64 combinations of 6 bars and spaces as shown in the font table at the

end of this document, where a 1 is a bar and a 0 is a space, arranged as a 6 bit binary number.

The dLSoft PDF fonts are provided in four element height/width ratios:

Font name element height/width ratio

PD2x 2 : 1

PD3x 3 : 1

PD4x 4 : 1

PD5x 5 : 1

The dLSoft fonts are also provided in different weights, to allow for ink spread during wet ink printing and the line

The PDF417 control

The PDFOCX control is an Active-X control which simplifies the use of barcodes in Active-X containers such as Visual


ThePDFOCX control may be placed on a form in most applications which support Active-X controls, such as Visual

Basic, Microsoft Access, etc. The PDF417 barcode properties may be specified through a series of Properties, either via

PDF417.NET Methods

Barcode()

Return Type: string


This method causes a barcode to be created as a sequence of character that, when displayed in the PDxx font will form

the barcode symbol.




Return Type: string


Barcode() method.

Common DLL features The following calls is common to several font kit DLLs. The XX in the call name is different for each kit as shown

below to avoid problems when more than one DLL is used within an application.

Aztec DLLs, XX = AZ

Databar DLLs, XX = DB

Datamatrix DLLs, XX = DM

PDF417 DLLs, XX = PD

QRCode DLLs, XX = QR

ErrorMessXX()

The ErrorMessXX() function call to the DLL is declared in C as

Int WINAPI ErrorMessXX(LPINT errorcode, LPSTR errortext)

And is use to obtain in errortext the text string corresponding to the error code pointed to by errorcode.

Note that the buffer pointed to by errortext must be declared as at least 36 characters (ie TCHAR errortext[36]) to

received the error messages.

Applies to all font kits.

EnumModeXX()

The EnumModeXX() function call to the DLL is declared in C as

Int WINAPI EnumModeXX(LPINT mode, LPSTR modename)

And is use to obtain in mode the text string corresponding to the mode value pointed to by mode.

Note that the buffer pointed to by modename must be declared as at least 36 characters (ie TCHAR errortext[36]) to

received the error messages.

Calls to EnumModeXX return the value of mode if the mode exists, or -1 otherwise.

Applies to all font kits.

MaxLevelXX()

The MaxLevelXX() function call to the DLL is declared in C as


Int WINAPI MaxLevelXX(LPINT mode)

And returns the maximum value of the sercurity level that may be used with the specified mode, or -1 if the mode does

not exist.

Applies to Aztec, Datamatrix, PDF417 and QR Code kits.

Common .NET component features

Using .NET Components in Visual Studio

Adding a .NET Component to the ToolBox To add a 2D-Font kit Component to the Visual Studio ToolBox, display the ToolBox and select the Components tab.

Right click on the Components pane and select Add/Remove Items (or Choose Items) from the pop-up menu displayed.

A dialog box is displayed listing the currently installed components. Ensure that the .NET Framework Components page

is displayed.

Push the Browse button and navigate to the location where you have installed or copied your .NET component and select

the DLL (e.g. Aztnet.dll).

Then push the Open button.

The list of installed components is now displayed, including your 2D-font.NET component. Ensure that the checkbox

alongside the component name is checked. Now push the OK button.

The component appears as an icon on the ToolBox Components pane, with one of the following class names alongside:

Component .NET name DLL

Aztec Font Kit.NET Aztnet Aztnet.dll

Datamatrix Font.NET Dmfnet Dmfnet.dll

QR Code Font.NET Qrcnet Qrcnet.dll

PDF417 Font.NET Pdfnet Pdfnet.dll

Adding a .NET component to a project. With a project's form open in design mode drag the .NET component icon from the toolbox onto the form.

The component icon appears on the panel below the form – it does NOT appear on the form itself. The instance of the

component will be given a default name (eg Aztnet1) which appears in the properties panel when the component is

selected. A single Form may contain any number of .NET Components. The first to be added will be called Aztnet1, the

second Aztnet2, and so on; the names may be changed by the user by modifying the Name property within the Properties

box.

The properties panel also displays all other settable properties for the component, and these values will be used as

defaults unless properties are changed programmatically within your project.


Setting and retrieving property values programmatically The .NET Components may be operated entirely by setting or retrieving Property values programmatically.

Clicking on the Barcode Component in the panel under the form when Visual Studio's Properties box is displayed will

show the current settings for component's available properties. Most of these may be edited using the Properties box, or

may have their values set from within the user's program by statements of the kind

Aztnet1.Caption="123456789" Visual Basic

Abcnet1.Caption="123456789"; C#

The Component properties that are set AFTER a barcode has been created may be retrieved within user's

programs by statements of the kind:

x=Aztnet1.Error Visual Basic

x=Aztnet1.Error; C#

Setting properties through the Barcode properties dialog box Using the Method Properties() causes the Barcode properties dialog to be displayed. This displays all settable properties

in a convenient form and enables changes to be made by selecting from drop-down lists or entering values into edit

boxes.

The example shown above is for the PDF417 Font Kit


Displaying a barcode on a form To display a barcode on a form a TextBox is used to hold the characters and the Font property of the TextBox set to a

suitable size of the relevant font (eg. AZTW or PD3W).

For example:

Private Sub DoBarcode() Visual Basic

Abcnet1.Caption="123456789

TextBox1.Texte=Aztnet1.Barcode()

End Sub

private void DoBarcode() C#

{

aztnet1.Caption="123456789";

textBox1.Text=aztnet1.Barcode();

}

Printing a barcode

Printing the text returned by the Barcode() call may be accomplished by any of the printing techniques available for

Visual Studio project. However, probably the most useful approach is to use the DrawString() method in a PrintPage

handler as illustrated below, and in the example provided with the components:

Visual Basic

Private Sub PrintDocument1_PrintPage(ByVal sender As System.Object, ByVal e As

System.Drawing.Printing.PrintPageEventArgs) Handles PrintDocument1.PrintPage

Dim br As Brush

Dim ff As New Font(“AZTW”, 8, FontStyle.Regular)

br = New SolidBrush(Color.Black)

e.Graphics.PageUnit = GraphicsUnit.Document '

e.Graphics.DrawString(Aztnet1.barcode(), ff, br, 100.0F, 300.0F)

' Indicate that this is the last page to print.

e.HasMorePages = False

End Sub

While the PageUnit setting can be any of the allowed values, the example above uses the highest resolution setting

(Document, equivalent to 300 units per inch).

Licensing the component The .NET components will behave as Testware versions (generating scrambled barcode and pattern strings) unless

correctly licensed.

Single computer version of the components are licensed for use only on a single computer. Developer versions permit

applications built with the.NET components to be distributed up to a maximum distribution of 10,000 copies.




Aztnet1.Serial="12345" for VB

aztnet1.Serial="12345"; for C#

.NET Information properties

Note that the barcode symbol is determined only when this Barcode() method is called, so the information properties are

not available until this method has been called.

Error

Type: integer

Returns a value representing the error code if a valid barcode image cannot be created. Otherwise returns 0.

Read only. Do not set this property.

The error codes and corresponding Status property values are shown below:

Status

Type: string

Returns a string interpreting the value of the Error property.

The error codes and corresponding Status property values are shown below:

Error Status

0 OK

1 Illegal character in data

2 Wrong data length

3 Error in barcode data

9 Other error


Pattern

Type: String

Returns: A string containing a pattern of digit characters which represent the bars and spaces in the barcode

symbol.


The pattern string returned for a PDF417 symbol consists of the sequence of digits used to represent the thickness of bars

and spaces alternately in the symbol (starting with the first bar), arranged by row. Bar height is at the user’s choice. Each

row is separated by a newline (\n or CHR(10)) characters.

The pattern string returned for an Aztec, Datamatrix or QR Code symbol consists of the sequence of characters used to

create the symbol, arranged by row, with a ‘1’ for a black square and a ‘0’ for a white square. Each row is separated by a

newline (\n or CHR(10)) characters.


.NET Component Methods

Barcode()

Return Type: string

This method causes a barcode to be created as a string of characters that, when displayed in the AZTx font will form the

barcode symbol.



Properties()

Return Type: BOOL

Displays the Barcode properties dialog for the component.

Returns TRUE if the user exits the dialog by pushing the OK button and sets all component properties to those specified

in the dialog.

Returns FALSE if the user exits the dialog by pushing the Cancel button.

.NET Standard components The .NET Standard components share most of the properties with the .NET components described above and have been

built to the .Net Standard 2.0. Note that only Developer licence versions of the kits can use .NET Standard components.

The components may be distinguished from the normal components by the s at the end of the name, so the components

are:

Component .NET name

Aztec Font Kit.NET Aztnets

Datamatrix Font.NET Dmfnets

QR Code Font.NET Qrcnets

PDF417 Font.NET Pdfnets

These components do not include a Properties dialog, so all properties must be set through code.

A sample demo application (using VB.Net and .Net v 4.6.2) and source code is included and will be found in the NetStd

folder of the samples.

Common Control Features All the controls have property pages that may be displayed and which enable properties to be set by the user.


The example shown above is for the Datamatrix ont Kit.

Common control methods

The following methods are common to all font kit OCX controls.

BarSave()

Int BarSave(LPSTR filename)

Causes the control to save the barcode characters into a text file. Filename must be the fully qualified file name,

complete with .TXT extension – such as that available from the Windows SaveDialog control.

The methods returns the number of bytes saved in the file, or 0 if an error occurs.

VB Example:

Ff$=”C:\test.txt”

BarSave(Ff$)

BarCopy()

Int BarCopy(void)

Copies the barcode text to the Windows clipboard, from where it may be pasted into other applications.

Note that only the text is copied; pasted text will need to be set into the appropriate font before a barcode will be seen.

VB Example

BarCopy()

GetModeName()

BSTR GetModeName(LPINT mode) for Aztec and DataMatrix font kits.

BSTR GetModeName(LPINT code, LPINT mode) for the PDF font kit, where the code parameter contains 0 for

PDF417 barcodes or 1 for Micro PDF barcodes.


Return the name of 2D mode for the barcode type. For example, DataMatrix barcodes have the mode name “Square” for

mode=0 and “Rectangular” for mode=1.

An invalid value in mode will return an empty string, so this method may be used for enumerating the available modes;

for example:

For i = 0 To 10

x$ = Aztocx1.GetModeName(i)

If (Len(x$) > 0) Then

Combomode.AddItem (x$)

Else

Exit For

End If

Next

GetMaxLevel()

Int GetMaxLevel(LPINT mode) for Aztec and DataMatrix font kits.

Int GetMaxLevel(LINT code. LPINT mode) for the PDF font kit, where the code parameter contains 0 for PDF417

barcodes or 1 for Micro PDF barcodes.

Returns the number of security levels valid for the mode. For example, Aztec in Normal mode can have 99 levels, but in

Compact mode has only 4.

VB Example

Mode=0

N=GetMaxLevel(Mode)

GetError()

BSTR GetError(LPINT errorcode)

The GetError(Errorcode) method returns the text (a BSTR string) of the error message corresponding to the Errorcode

value. So a string variable may be filled with the error message using

X$=Uniocx1.GetError(Uniocx.Errorcode)

Using with CreateObject While the components can be added to applications at design-time (as described in the sections above) they may also be

created at run-time using CreateObject.

A simple example of code is shown here for a VB6 application consisting of a form containing a TextBox:

Public abc As Object

Private Sub Form_Load()

Set abc = CreateObject("AZTOCX.AztocxCtrl.1")

abc.Caption = "Hello World"

Text2.Text = abc.Output

End Sub


When the form loads the abc object is created, some of its properties are specified, then the resulting barcode characters

placed in the TextBox.

The string in the CreateObject function is the Class name of the component. The Table below shows the class names for

the Barcode 2D-Font Kit Component classes.

Aztec Font Kit AZTOCX.AztocxCtrl.1

Databar Font Kit DBAROCX.DbarocxCtrl.1

Datamatrix Font Kit DMFOCX.DmfocxCtrl.1

PDF417 Font Kit PDFOCX.PdfocxCtrl.1

QR Code Font Kit QROCX.QRocxCtrl.1

Objects created this way may have their properties set in code or by providing a call to one of the components methods,

such as

Abc.ShowProps

Error Codes A negative value returned from the Bar2Dxxf() calls indicates one of the following errors:

1 Invalid data length

2 Invalid code type

3 Invalid parameters

4 Illegal character in data

5 Invalid embedded code

6 Line width too small

7 Font error

8 Error creating image

9 Error creating barcode
