Manual - UPC-E

Introduction

UPC-E code is the shorter version of UPC-A code. You must provide a UPC-A code with 11 numbers (without the checksum) or directly the UPC-E code with 6 numbers.

Some UPC-A codes can't be converted into UPC-E code, in this case, an error will be displayed.

This class inherits the BakeryBarcode1D class.

Method explanations

• thickness={thickness} — Specifies the thickness of the barcode
  Description

  The thickness of the barcode in pixels. This is the vertical size.
• label={label} — Sets the label
  Description

  The text label will be written below or above the barcode depending on the barcode. You can write the special value BakeryBarcode1D.Label if you would like your text to be chosen automatically. It will be the value passed to the text={} method.
• font={font} — Sets the text font for the label
  Description

  The value of the argument must be an instance of the BakeryFontFile class.
• displayChecksum={display} — Specifies the checksum to be added to the label
  Description

  Setting true will append the checksum to the default label.
  The default value is true.

• text={text} — Analyzes a text message to draw afterwards
  Description

  The data you pass to the text argument must be supported by the type of barcode you use.
  Check each barcode's introduction section to obtain more information on how to use this method within each symbology.
• scale={scale} — Sets the scale of the barcode
  Description

  The barcode will be x times bigger. Then a pixel will be x by x for its size.
• foregroundColor={color} — Sets the color of the bars
  Description

  Sets the color of the bars of the barcode. By default, the color is black. This argument can be a BakeryColor class or any other argument that BakeryColor can accept in its constructor.
• backgroundColor={color} — Sets the color of the spaces
  Description

  Sets the color of the spaces of the barcode. By default, the color is white. This argument can be a BakeryColor class or any other argument that BakeryColor can accept in its constructor.
• offsetX={value} — Sets the X offset
  Description

  Specifies the X offset of the barcode in pixels multiplied by the scale.
• offsetY={value} — Sets the Y offset
  Description

  Specifies the Y offset of the barcode in pixels multiplied by the scale.
