Unicode Image – Native Barcode Generation from a Text Font
Unicode Image refers to a patented process that generates a native barcode image from a mono-spaced Unicode font such as Courier New. IDAutomation has been utilizing this technology since 2006 and licensing of this technology is available by request.
Products using this technology are usually referred to as “Native Generators” because of their ability to generate symbols without the need to install a barcode font.
Several products make use of this technology, including:
- .NET Barcode Generator
- Crystal Reports Native Generator
- FileMaker Barcode Generator
- Google Sheets | Docs | Apps Script Barcode Generator
- Microsoft Access Barcode Generator
- Microsoft Excel Native Barcode Generator
- SSRS Native Generator
A sizing issue may occur when using Unicode Image products with 2D barcodes. The font “Courier New” tends to create a wider 2D symbol and “Consolas” tends to create a taller symbol in 2D Matrix barcode types. In some applications, such as Crystal Reports, a taller symbol can be shortened by changing the line spacing. For example, if “Consolas” is creating a symbol that is too tall, set the line spacing under the Paragraph tab to .95 or another size that creates a square symbol.
IDAutomation also offers the “IDAutomation2D S” font which can be used in place of a system font. To use this font, download the Universal 2D Font and install the “IDAutomation2D S” font from the package. After installation, select the “IDAutomation2D S” font instead of Courier New or Consolas to generate the symbols. When using the IDAutomation2D S font, the font point size will need to be doubled for the symbol to be the same size as the system font.
