Method explanations

  • setScaleX($scaleX) — Sets the scaling X for the barcode
    Description
    The width in pixel of one module.
    The default value is 1.
    Note that this method is protected.
  • setScaleY($scaleY) — Sets the scaling Y for the barcode
    Description
    The height in pixel of one module.
    The default value is 1.
    Note that this method is protected.
  • parse($text) — Analyzes a $text message to draw afterwards
    Description
    The data you pass to the $text argument must be supported by the type of barcode you use.
    Check each barcode's introduction section to obtain more information on how to use this method within each symbology.
  • draw($im) — Draws the barcode on the $im
    Description
    The value of the $im argument must be an image resource. The size of the image can be defined by the value received from getDimension().
  • getDimension($w, $h) — Returns an array containing the required size for the image
    Description
    Returns an array in which the first index is the image width and the second index is the image height.
    The arguments are used to specify the starting point of the drawing. Should be 0 for both.
    The BCGDrawing class uses this method to create the image resource.
    Returns
    array(int, int) - [0] is the width, [1] is the height
  • getScale() — Gets the scale of the barcode
    Description
    Gets the scale of the barcode. The value is the number of the "smallest" unit in pixel.
    Returns
    int - value in pixels
  • setScale($scale) — Sets the scale of the barcode
    Description
    The barcode will be $x times bigger. Then a pixel will be $x by $x for its size.
  • getForegroundColor() — Gets the color of the bars
    Description
    Gets the color of the bars of the barcode.
    Returns
  • setForegroundColor($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 BCGColor class or any other argument that BCGColor can accept in its constructor.
  • getBackgroundColor() — Gets the color of the spaces
    Description
    Gets the color of the spaces of the barcode.
    Returns
  • setBackgroundColor($color) — Sets the color of the spaces
    Description
    Sets the color of the spaces of the barcode. By default, the color is white. This argument can be a BCGColor class or any other argument that BCGColor can accept in its constructor.
  • setColor($fg, $bg) — Sets the color of the bars and spaces
    Description
    An easy and fast method to set the color of the bars and spaces. Check the setForegroundColor() and setBackgroundColor().
  • getOffsetX() — Gets the X offset
    Description
    Gets the X offset of the barcode in pixels. The value isn't multiplied by the scale.
    Returns
    int - value in pixels
  • setOffsetX($value) — Sets the X offset
    Description
    Specifies the X offset of the barcode in pixels multiplied by the scale. The required size returned by getDimension() will be modified accordingly.
  • getOffsetY() — Gets the Y offset
    Description
    Gets the Y offset of the barcode in pixels. The value isn't multiplied by the scale.
    Returns
    int - value in pixels
  • setOffsetY($value) — Sets the Y offset
    Description
    Specifies the Y offset of the barcode in pixels multiplied by the scale. The required size returned by getDimension() will be modified accordingly.
  • addLabel($label) — Adds a label to the graphic
    Description
    Adds a BCGLabel object to the drawing.
  • removeLabel($label) — Removes a label from the graphic
    Description
    Removes a specific BCGLabel object from the drawing.
  • clearLabels() — Removes the labels from the graphic
    Description
    Clears the BCGLabel objects from the drawing.
