Constructor Detail

SVGOutput

public SVGOutput(Writer writer,
         Font font,
         Color fgColor,
         Color bgColor,
         double scalar,
         String units)

Creates a new instance of SVGOutput.

Parameters:

writer - The Writer to output the SVG text to

font - The font for text rendering (only if Barcode has drawText set to true)

fgColor - Foreground color

bgColor - Background color

scalar - The scalar value to convert to units. if barWidth is 1, and you want the smallest bar to be 1/128 of an inch, this should be set to 1.0/128, and units should be set to "in"

units - The units for the scalar, above. "in", "cm", "mm", "px" are acceptable values.

Method Detail

beginDraw

public void beginDraw()
