public class PDFOutput
extends Output

This class renders the graph to a PDF document defined using version 1.2 or earlier of the Big Faceless PDF library. The latest version of this library is version 2, so class should only be used by those that already own an older version of the PDF library. See PDF2Output for a class that works with latest version.

PDFOutput

public PDFOutput(PDFPage p,
                 float left,
                 float top,
                 float right,
                 float bottom)

Create a new PDFOutput class to render the graph to the specified page. This class assumes that the page has the default canvas settings - i.e. it's measured in points from the bottom left of the page.

Parameters:

p - a PDFpage object measured in points from the bottom-left

left - the left margin of the graph, in points from the left of the page

bottom - the bottom margin of the graph, in points from the bottom of the page

width - the width of the graph in points

height - the height of the graph in points
