040/**
041 * A class that can be used to map AWT/Java2D fonts to PDF built-in font names.
042 * This is a very minimal way to support fonts in this {@link PDFGraphics2D} 
043 * implementation.
044 * <br><br>
045 * Note that there is an option to draw text as vector graphics which you can
046 * specify using the rendering hint {@link PDFHints#KEY_DRAW_STRING_TYPE}.
047 * This can be useful, for example, if you need to display characters (such
048 * as the euro symbol) that are not supported by the PDF built-in fonts.
