ITF-14 Barcode FAQ in ASP.NET Barcode Library SDK

Using ITF-14 ASP.NET web server barcode control library to generate and create ITF-14 barcode images in ASP.NET applications is simple and time-saving. Developers are able to implement ITF-14 barcode images into ASP.NET web server without using Visual Studio. While programmers may integrate barcode images in Web Forms using C# or VB.NET class library.

This article tells about how to generate and customize ITF-14 barcode properties in ASP.NET web server applications using IIS with URL or using ASP.NET server control in Visual Studio Toolbox:

The data encodes in ITF-14 is numeric digits from 0 to 9. The value to encode passed to ASP.NET server library DLL should be 13 digits only because the 14th digit (the checksum) is automatically calculated by Terrek.Barcode Generator SDK. Users are free to input ITF-14 data via BarcodeData property.

The human-readable text of ITF-14 is flexible to be enabled or disabled in barcode symbols. Users may apply this property through DisplayData. Once enabling the input data in barcode symbol, text color, text space, and text font style are adjustable via TextColor, TextSpace, TextStyle property.

ITF-14 barcode symbol has a unique Bearer Bar that is usually mandatory. But for some specified applications, it can be removed. When a skewed scanning beam enters the barcode symbol through its top or bottom edge, this bar can help reduce the probability of misreads or short scans. Users may use BearerBarLnR, BearerBarTnB properties to customize bearer bar.

As the name specified, it means the ratio between wide bar and narrow bar, the value ranges from 2.0 to 3.0. The default is 2, developers may change the value through WideVSNarrow property.

Set property MeasuringUnit for properties BarWidth, BarHeight, MarginL and MarginT. Valid values are PIXEL(0), CM(1) and INCH(2). Default is PIXEL (0). With this UOM setting, users can control the whole barcode size to a unique type.

ITF-14 X, Y dimension means the bar width and bar height of ITF-14 barcode. In ASP.NET web server control DLL, they are BarWidth and BarHeight. The whole barcode image is changed according to the adjustment of bar width and bar height.

Web Stream Sample URL: http://YourDomain:Port/barcode/aspcontrol.aspx?Symbology=24&BarcodeData = 1234567891234&BarWidth=2&BarHeight=60;

If the breakdown parameters are unknown, you can set the width and height of the barcode image ImageWidth & ImageHeight directly. Once you enabled the image resize function, you only need to provide the size of entire barcode image. This intelligent ITF-14 will draw the barcode with reasonable parameters. The generated ITF-14 in ASP.NET project is 100% compatible with GS1 General Specifications.

Increasing the width of margins around the symbol is one way to enhance the readability of the ITF-14 barcode image. The ASP.NET barcode server control SDK set the left, right, top, and bottom margins separately with float values. The default value is 0. The properties in VS .NET barcode library are MarginL, MarginR, MarginB and MarginT

ITF-14 generated in ASP.NET barcode generator library can be displayed as Gif, Tiff, Bmp, Png, Jpeg and other image formats. Programmers may change the format using BarcodeFormat property. Besides, the created ITF-14 can be saved as Bitmap, Stream and Graphic .NET objects.

DPI (Dots per inch) is used commonly as the measure of printing resolution. It allows the customization of images created to support reading small barcodes with barcode readers. The resolution of image generated by ITF-14 generator could be managed with DPI. Users may change DotsPerInch property.

ITF-14 position in ASP.NET Web Forms may be influenced by two factors, one is barcode alignment, and the other is rotation. Programmers may set the position by Rotation and BarAlign respectively. Barcode alignment valid value is center(1), left(0) and right(2); barcode rotation valid value is 0(0), 90(1), 180(2) and 270(3) degree.

It is able to change barcode colors with ASP.NET barcode server library DLL. Both background color and foreground color are easy to be changed by manipulating ImageColor and BarColor respectively.
