Field Detail

• BASIC

  public static PdfGraphicExporter BASIC

  Exporter which uses the default font mapper. OK for standard fonts.

• GLYPH_TEXT

  public static PdfGraphicExporter GLYPH_TEXT

  Exporter which writes text as shapes not using fonts. Will generate reasonable output for any font without additional preparation. However, the output shapes are not perfect (visible only at huge magnification) and it may be less efficient if there's a lot of text (though possibly more efficient if there's very little).

Constructor Detail

• PdfGraphicExporter

  protected PdfGraphicExporter​()

  Constructor.

Method Detail

• createExternalFontExporter

  public static PdfGraphicExporter createExternalFontExporter​(java.net.URL fontsUrl)

  Returns an exporter which uses externally stored fonts. Output is perfect. A location must be provided for a resource giving a list of font locations. If the fonts can't be found, behaviour reverts to that of GLYPH_TEXT.

  Parameters:

  fontsUrl - location of a text file of font resource strings (typically file names or URLs of .ttf files)

  Returns:

  new exporter using external fonts

• exportGraphic

  public void exportGraphic​(Picture picture,
                            java.io.OutputStream out)
                     throws java.io.IOException

  Description copied from class: GraphicExporter
  Paints the given picture to an output stream using some graphics format or other. This method should not close the stream.

  Specified by:

  exportGraphic in class GraphicExporter

  Parameters:

  picture - picture to draw

  out - destination output stream

  Throws:

  java.io.IOException

• createGraphics

  public abstract java.awt.Graphics2D createGraphics​(com.lowagie.text.pdf.PdfContentByte pcb,
                                                     int width,
                                                     int height)

  Returns a graphics context which can be used to write to a given PDF content object. There is not a single obvious implementation of this method; the best way to do it depends on how text glyphs are to be rendered.

  Parameters:

  pcb - PDF content object

  width - in pixels

  height - in pixels

  Returns:

  new graphics context
