barcodelib C# Library

barcodelib supports a wide range of barcode symbologies for generating barcode images from string data. Supported types include:

• Code 128
• Code 93
• Code 39 (Extended / Full ASCII)
• Code11
• EAN-8
• FIM (Facing Identification Mark)
• UPC-A
• UPC-E
• Pharmacode
• MSI
• PostNet
• Standard 2 of 5
• ISBN
• Codabar
• Interleaved 2 of 5
• ITF-14
• Telepen
• UPC Supplemental 2
• JAN-13
• EAN-13
• UPC Supplemental 5
• IATA2of5

To generate a barcode image, use the Encode method on a Barcode instance. The method requires the following parameters:

• Type: The symbology to use (e.g., Type.UpcA).
• string: The data to be encoded.
• SKColor: The foreground color (e.g., SKColors.Black).
• SKColor: The background color (e.g., SKColors.White).
• int: The width of the image.
• int: The height of the image.

You can also set the IncludeLabel property to true to include a text label with the barcode.

var b = new Barcode();
b.IncludeLabel = true;
var img = b.Encode(Type.UpcA, "038000356216", SKColors.Black, SKColors.White, 290, 120);

The core of the library is the Barcode class. You can instantiate it using three different constructors:

1. Barcode(): Creates an empty instance. You must set the data and symbology via properties before encoding.
2. Barcode(string): Creates an instance with the provided data string.
3. Barcode(string, Type): Creates an instance with the provided data string and a specific symbology Type.

If you use the parameterless constructor, ensure you specify the data and type before calling the Encode method.

// Example of parameterless constructor usage
var b = new Barcode();
b.IncludeLabel = true;
var img = b.Encode(Type.UpcA, "038000356216", SKColors.Black, SKColors.White, 290, 120);
