public class Font extends Object implements Serializable
Font class represents fonts, which are used to
 render text in a visible way.
 A font provides the information needed to map sequences of
 characters to sequences of glyphs
 and to render sequences of glyphs on Graphics and
 Component objects.
 'g',
 LATIN SMALL LETTER G, is a character.
 A glyph is a shape used to render a character or a sequence of characters. In simple writing systems, such as Latin, typically one glyph represents one character. In general, however, characters and glyphs do not have one-to-one correspondence. For example, the character 'á' LATIN SMALL LETTER A WITH ACUTE, can be represented by two glyphs: one for 'a' and one for '´'. On the other hand, the two-character string "fi" can be represented by a single glyph, an "fi" ligature. In complex writing systems, such as Arabic or the South and South-East Asian writing systems, the relationship between characters and glyphs can be more complicated and involve context-dependent selection of glyphs as well as glyph reordering. A font encapsulates the collection of glyphs needed to render a selected set of characters as well as the tables needed to map sequences of characters to corresponding sequences of glyphs.
 Physical fonts are the actual font libraries containing glyph data
 and tables to map from character sequences to glyph sequences, using a font
 technology such as TrueType or PostScript Type 1.
 All implementations of the Java Platform must support TrueType fonts;
 support for other font technologies is implementation dependent.
 Physical fonts may use names such as Helvetica, Palatino, HonMincho, or
 any number of other font names.
 Typically, each physical font supports only a limited set of writing
 systems, for example, only Latin characters or only Japanese and Basic
 Latin.
 The set of available physical fonts varies between configurations.
 Applications that require specific fonts can bundle them and instantiate
 them using the createFont method.
 
Logical fonts are the five font families defined by the Java platform which must be supported by any Java runtime environment: Serif, SansSerif, Monospaced, Dialog, and DialogInput. These logical fonts are not actual font libraries. Instead, the logical font names are mapped to physical fonts by the Java runtime environment. The mapping is implementation and usually locale dependent, so the look and the metrics provided by them vary. Typically, each logical font name maps to several physical fonts in order to cover a large range of characters.
 Peered AWT components, such as Label and
 TextField, can only use logical fonts.
 
For a discussion of the relative advantages and disadvantages of using physical or logical fonts, see the Internationalization FAQ document.
Font
 can have many faces, such as heavy, medium, oblique, gothic and
 regular. All of these faces have similar typographic design.
 
 There are three different names that you can get from a
 Font object.  The logical font name is simply the
 name that was used to construct the font.
 The font face name, or just font name for
 short, is the name of a particular font face, like Helvetica Bold. The
 family name is the name of the font family that determines the
 typographic design across several faces, like Helvetica.
 
 The Font class represents an instance of a font face from
 a collection of  font faces that are present in the system resources
 of the host system.  As examples, Arial Bold and Courier Bold Italic
 are font faces.  There can be several Font objects
 associated with a font face, each differing in size, style, transform
 and font features.
 
 The getAllFonts method
 of the GraphicsEnvironment class returns an
 array of all font faces available in the system. These font faces are
 returned as Font objects with a size of 1, identity
 transform and default font features. These
 base fonts can then be used to derive new Font objects
 with varying sizes, styles, transforms and font features via the
 deriveFont methods in this class.
 
Font supports most
 TextAttributes.  This makes some operations, such as
 rendering underlined text, convenient since it is not
 necessary to explicitly construct a TextLayout object.
 Attributes can be set on a Font by constructing or deriving it
 using a Map of TextAttribute values.
 
The values of some TextAttributes are not
 serializable, and therefore attempting to serialize an instance of
 Font that has such values will not serialize them.
 This means a Font deserialized from such a stream will not compare
 equal to the original Font that contained the non-serializable
 attributes.  This should very rarely pose a problem
 since these attributes are typically used only in special
 circumstances and are unlikely to be serialized.
 
FOREGROUND and BACKGROUND use
 Paint values. The subclass Color is
 serializable, while GradientPaint and
 TexturePaint are not.CHAR_REPLACEMENT uses
 GraphicAttribute values.  The subclasses
 ShapeGraphicAttribute and
 ImageGraphicAttribute are not serializable.INPUT_METHOD_HIGHLIGHT uses
 InputMethodHighlight values, which are
 not serializable.  See InputMethodHighlight.Paint and
 GraphicAttribute can make them serializable and
 avoid this problem.  Clients who use input method highlights can
 convert these to the platform-specific attributes for that
 highlight on the current platform and set them on the Font as
 a workaround.
 The Map-based constructor and
 deriveFont APIs ignore the FONT attribute, and it is
 not retained by the Font; the static getFont(java.util.Map<? extends java.text.AttributedCharacterIterator.Attribute, ?>) method should
 be used if the FONT attribute might be present.  See TextAttribute.FONT for more information.
Several attributes will cause additional rendering overhead
 and potentially invoke layout.  If a Font has such
 attributes, the hasLayoutAttributes()
Note: Font rotations can cause text baselines to be rotated. In order to account for this (rare) possibility, font APIs are specified to return metrics and take parameters 'in baseline-relative coordinates'. This maps the 'x' coordinate to the advance along the baseline, (positive x is forward along the baseline), and the 'y' coordinate to a distance along the perpendicular to the baseline at 'x' (positive y is 90 degrees clockwise from the baseline vector). APIs for which this is especially important are called out as having 'baseline-relative coordinates.'

public Font(String name, int style, int size)
Font from the specified name, style and
 point size.
 
 The font name can be a font face name or a font family name.
 It is used together with the style to find an appropriate font face.
 When a font family name is specified, the style argument is used to
 select the most appropriate face from the family. When a font face
 name is specified, the face's style and the style argument are
 merged to locate the best matching font from the same family.
 For example if face name "Arial Bold" is specified with style
 Font.ITALIC, the font system looks for a face in the
 "Arial" family that is bold and italic, and may associate the font
 instance with the physical font face "Arial Bold Italic".
 The style argument is merged with the specified face's style, not
 added or subtracted.
 This means, specifying a bold face and a bold style does not
 double-embolden the font, and specifying a bold face and a plain
 style does not lighten the font.
 
 If no face for the requested style can be found, the font system
 may apply algorithmic styling to achieve the desired style.
 For example, if ITALIC is requested, but no italic
 face is available, glyphs from the plain face may be algorithmically
 obliqued (slanted).
 
Font name lookup is case insensitive, using the case folding rules of the US locale.
 If the name parameter represents something other than a
 logical font, i.e. is interpreted as a physical font face or family, and
 this cannot be mapped by the implementation to a physical font or a
 compatible alternative, then the font system will map the Font
 instance to "Dialog", such that for example, the family as reported
 by getFamily will be "Dialog".
 
name - the font name.  This can be a font face name or a font
 family name, and may represent either a logical font or a physical
 font found in this GraphicsEnvironment.
 The family names for logical fonts are: Dialog, DialogInput,
 Monospaced, Serif, or SansSerif. Pre-defined String constants exist
 for all of these names, for example, DIALOG. If name is
 null, the logical font name of the new

 The style argument is an integer bitmask that may
 be PLAIN, or a bitwise union of BOLD and/or
 ITALIC (for example, ITALIC or BOLD|ITALIC).

 integer bitmasks then the style is set to PLAIN.size - the point size of the FontGraphicsEnvironment.getAllFonts(),

 Most users are familiar with the idea of using point size to
 specify the size of glyphs in a font. This point size defines a
 measurement between the baseline of one line to the baseline of the
 following line in a single spaced text document. The point size is
 based on typographic points, approximately 1/72 of an inch.
 The Java(tm)2D API adopts the convention that one point is equivalent to one unit in user coordinates. When using a normalized transform for converting user space coordinates to device space coordinates 72 user space units equal 1 inch in device space. In this case one point is 1/72 of an inch.

public static Font getFont(String nm)
Font object from the system properties list.
 nm is treated as the name of a system property to be
 obtained.  The String value of this property is then
 interpreted as a Font object according to the
 specification of Font.decode(String)
 If the specified property is not found, or the executing code does
 not have permission to read the property, null is returned instead.nm - the property nameFont object that the property name
          describes, or null if no such property exists.NullPointerException - if nm is null.decode(String)public static Font decode(String str)
Font that the str
 argument describes.
 To ensure that this method returns the desired Font,
 format the str parameter in
 one of these ways
 
"PLAIN", "BOLD", "BOLDITALIC", or
 "ITALIC", and pointsize is a positive decimal integer
 representation of the point size.
 For example, if you want a font that is Arial, bold, with
 a point size of 18, you would call this method with:
 "Arial-BOLD-18".
 This is equivalent to calling the Font constructor :
 new Font("Arial", Font.BOLD, 18);
 and the values are interpreted as specified by that constructor.
 A valid trailing decimal field is always interpreted as the pointsize. Therefore a fontname containing a trailing decimal value should not be used in the fontname only form.
If a style name field is not one of the valid style strings, it is interpreted as part of the font name, and the default style is used.
Only one of ' ' or '-' may be used to separate fields in the input. The identified separator is the one closest to the end of the string which separates a valid pointsize, or a valid style name from the rest of the string. Null (empty) pointsize and style fields are treated as valid fields with the default value for that field.
 Some font names may include the separator characters ' ' or '-'.
 If str is not formed with 3 components, e.g. such that
 style or pointsize fields are not present in
 str, and fontname also contains a
 character determined to be the separator character
 then these characters where they appear as intended to be part of
 fontname may instead be interpreted as separators
 so the font name may not be properly recognised.
 
 The default size is 12 and the default style is PLAIN.
 If str does not specify a valid size, the returned
 Font has a size of 12.  If str does not
 specify a valid style, the returned Font has a style of PLAIN.
 If you do not specify a valid font name in
 the str argument, this method will return
 a font with the family name "Dialog".
 To determine what font family names are available on
 your system, use the
 GraphicsEnvironment.getAvailableFontFamilyNames() method.
 If str is null, a new Font
 is returned with the family name "Dialog", a size of 12 and a
 PLAIN style.
str - the name of the font, or nullFont object that str

Font from the system properties
 list.  As in the getProperty method of
 System, the first
 argument is treated as the name of a system property to be
 obtained.  The String value of this property is then
 interpreted as a Font object.
 
 The property value should be one of the forms accepted by
 Font.decode(String)
 If the specified property is not found, or the executing code does not
 have permission to read the property, the font
 argument is returned instead.

GlyphVector object, performing full
 layout of the text if possible.  Full layout is required for
 complex text, such as Arabic or Hindi.  Support for different
 scripts depends on the font and implementation.
 
 Layout requires bidi analysis, as performed by
 Bidi, and should only be performed on text that
 has a uniform direction.  The direction is indicated in the
 flags parameter,by using LAYOUT_RIGHT_TO_LEFT to indicate a
 right-to-left (Arabic and Hebrew) run direction, or
 LAYOUT_LEFT_TO_RIGHT to indicate a left-to-right (English)
 run direction.
 
In addition, some operations, such as Arabic shaping, require context, so that the characters at the start and limit can have the proper shapes. Sometimes the data in the buffer outside the provided range does not have valid data. The values LAYOUT_NO_START_CONTEXT and LAYOUT_NO_LIMIT_CONTEXT can be added to the flags parameter to indicate that the text before start, or after limit, respectively, should not be examined for context.
All other values for the flags parameter are reserved.
