Barcode-Lib4J – A free Java Library for 1D and 2D Barcodes

BARCODE-Lib4J – Free Java library for precise drawing, printing and storage of 1D & 2D barcodes in vector (PDF, EPS, SVG) and raster (PNG, BMP, JPG) images. Proven in practice through its use in our software products.

Features

  • Drawing and printing 1D & 2D barcodes using Java2D (java.awt.Graphics2D)
  • Exporting to PDF: Compliance with PDF/X-1a:2001 for CMYK and PDF/X-3:2002 for RGB
  • Exporting to EPS: Generation of an optional embedded TIFF preview, supports RGB and CMYK colors
  • Exporting to SVG: Supports RGB colors only
  • Barcode precision: Coordinates are stored with up to 6 decimal places in all supported vector formats
  • Exporting to PNG, BMP, JPG: DPI resolution stored in file header. No unwanted effects such as aliasing, etc.
  • Adjustment of bar widths to printer resolution (essential for proper barcode quality at <= 600 dpi)
  • Bar width reduction/correction (useful for addressing ink spread on inkjet printers)
  • Barcodes include minimum distances ("quiet zones")
  • Barcode number placement options: on top, bottom, or invisible
  • Customizable plain text line: font + font size, spacing, modifiable content
  • Automatic font size adjustment, if desired
  • Advanced setting: enables printing with a user-defined module width
  • Optionally transparent background (Supported in EPS, PDF, SVG and PNG)
  • Rotation in 90-degree increments
  • Configurable ratio from 2:1 to 3:1 for barcode types that support it
  • Add-On 2/5 for barcodes like EAN-13, EAN-8, ISBN-13 and UPC-A, second plain text line for ISBN and ISMN
  • Comprehensive support for GS1 barcodes: Includes data integrity checks, validation of application identifiers, checks for length and content of user data, verification/calculation of the check digit in SSCC and GTIN and more.
