EAN-8 Barcode FAQ in WinForms Barcode Library DLL

It is easy and fast to generate and embed high quality EAN-8 barcode images in .NET windows applications using EAN-8 .NET barcode component DLL for WinForms with various barcode generation method including C# or VB.NET class library. The inserted EAN-8 barcode images in .NET are flexible to be changed to required barcode size, barcode image, barcode color with simple adjustments.

This article tells about EAN-8 barcode image customization in .NET windows applications with .NET barcode control DLL installed in VS Toolbox from the following aspects:

The data encodes in EAN-8 is numeric digits from 0 to 9. The value to encode passed to .NET barcode library SDK must be 7 digits only because the 8th digit (the checksum) is automatically calculated by Terrek.Barcode Generator SDK. Users are free to input EAN-8 barcode data via BarcodeData property.

The human-readable text of EAN-8 is flexible to be enabled or disabled in barcode symbols. Users may apply this property through DisplayData. To enable barcode human readable text, set the DisplayData to true. Once enabling the input data in barcode symbol, text color, text space, and text font style are adjustable via TextColor, TextSpace, TextStyle.

While by disabling the human-readable text, developers may replace it with other necessary information such as company logo, telephone number, fax number, and other special characters that has no connection with barcode data.

EAN-8 barcode library SDK allows users to add 2 or 5 digits supplemental data to the EAN-8 barcode. Once encode the EAN-8 add-on barcodes, the size related properties needs to be set. Users may add supplemental digits using Symbolproperty and customize add-on barcode size by adjusting AddOnData, AddOnHeight, AddOnMargin respectively.

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

To customize the module size of EAN-8 barcode, users needs to adjust the bar width and bar height through BarWidth and BarHeight property. The whole barcode image is changed according to the adjustment of bar width and bar height.

If the module sizes of bar width and bar height are unknown, you can set the width and height of the barcode image directly though ImageHeight and ImageWidth property. Once you enabled the image resize function, you only need to provide the size of entire barcode image. This intelligent UPC-E will draw the barcode with reasonable parameters.

Increasing the width of margins around the symbol is one way to enhance the readability of the EAN-8 barcode image by barcode scanner. The .NET barcode control library 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 DLL are MarginL, MarginR, MarginB and MarginT.

EAN-8 embedded in .NET Barcode Control DLL 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 EAN-8 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 EAN-8 control library SDK could be managed with DotsPerInch. All in all, whether the resolution is, all types of barcode printers are suitable for printing EAN-8 with high quality and clear image.

EAN-8 image placement in .NET windows applications 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. The valid value for alignment is left, center and right; the valid value for rotation is 0, 90, 180 and 270 degrees.

It is possible to change barcode colors with .NET Barcode Control Library DLL. Both background color and foreground color are easy to be changed by manipulating ImageColor and BarColor respectively. The default value is black and white, users are flexible to change them to whatever you want.

Using .NET barcode generator library SDK for Windows applications, users are entitled to create and develop EAN-8 barcode images in the following .NET environments with flexibility. Guide to generate EAN-8 barcode images in .NET WinForms.
