      • setDPI

        public void setDPI​(float dpi)
        Sets the effective DPI (Dots Per Inch) of the screen. You should normally never need to override the dpi, as it is already set to the system default by Toolkit.getDefaultToolkit().getScreenResolution() . You can override the value if you want to scale the fonts for accessibility or printing purposes. Currently the DPI setting only affects font sizing.
        Parameters:
        dpi - The new dPI value

      • setBaseURL

        public void setBaseURL​(java.lang.String url)
        Sets the baseURL attribute of the RenderingContext object
        Parameters:
        url - The new baseURL value
      • isPaged

        public boolean isPaged()
        Returns true if the currently set media type is paged. Currently returns true only for print , projection , and embossed , handheld , and tv . See the media section of the CSS 2.1 spec for more information on media types.
        Returns:
        The paged value
      • isInteractive

        public boolean isInteractive()
      • setInteractive

        public void setInteractive​(boolean interactive)
      • isPrint

        public boolean isPrint()
      • setPrint

        public void setPrint​(boolean print)
      • setFontMapping

        public void setFontMapping​(java.lang.String name,
                                   java.awt.Font font)

        Adds or overrides a font mapping, meaning you can associate a particular font with a particular string. For example, the following would load a font out of the cool.ttf file and associate it with the name CoolFont :

           Font font = Font.createFont(Font.TRUETYPE_FONT,
           new FileInputStream("cool.ttf");
           setFontMapping("CoolFont", font);
         

        You could then put the following css in your page

           p { font-family: CoolFont Arial sans-serif; }
         

        You can also override existing font mappings, like replacing Arial with Helvetica.

        Parameters:
        name - The new font name
        font - The actual Font to map
