    Modifier and Type
    Method
    Description
    InputStream
    getJPEG(String svgString, Float quality)
    Parses the given SVG graphic source, paints the parsed SVG graphic into a newly-created BufferedImage, and returns an InputStream for reading the BufferedImage in JPEG format at the given quality level.
    InputStream
    getPNG(String svgString)
    Parses the given SVG graphic source, paints the parsed SVG graphic into a newly-created BufferedImage, and returns an InputStream for reading the BufferedImage in PNG format.
    void
    writeJPEG(OutputStream os, String svgString, Float quality)
    Parses the given SVG graphic source, paints the parsed SVG graphic into a newly-created BufferedImage, and writes the BufferedImage as a JPEG to os at the given quality level.
    void
    writePNG(OutputStream os, String svgString)
    Parses the given SVG graphic source, paints the parsed SVG graphic into a newly-created BufferedImage, and writes the BufferedImage as a PNG to os.

  • Method Details

    • writePNG

      void writePNG(OutputStream os, String svgString) throws IOException
      Parses the given SVG graphic source, paints the parsed SVG graphic into a newly-created BufferedImage, and writes the BufferedImage as a PNG to os.
      Parameters:
      os - the OutputStream where the PNG data is written.
      svgString - the SVG graphic source.
      Throws:
      IOException

    • writeJPEG

      void writeJPEG(OutputStream os, String svgString, Float quality) throws IOException
      Parses the given SVG graphic source, paints the parsed SVG graphic into a newly-created BufferedImage, and writes the BufferedImage as a JPEG to os at the given quality level.
      Parameters:
      os - the OutputStream where the JPEG data is written.
      svgString - the SVG graphic source.
      quality - a number between 0 and 1, with 1 representing the best quality and 0 representing the least quality but smallest file size. Pass null to use the default quality.
      Throws:
      IOException

    • getPNG

      InputStream getPNG(String svgString) throws IOException
      Parses the given SVG graphic source, paints the parsed SVG graphic into a newly-created BufferedImage, and returns an InputStream for reading the BufferedImage in PNG format.
      Parameters:
      svgString - the SVG graphic source.
      Returns:
      an InputStream for reading a rasterization of the SVG graphic in PNG format.
      Throws:
      IOException
