public class Font

extends Object

implements Serializable

The Font class represents fonts. The capabilities of this class have been extended over the java.awt.Font class in JDK(tm) 1.1 and earlier releases to provide for developers the ability to utilize more sophisticated typographic features.

It is important to present the concepts behind using the words character and glyph separately. A character is a symbol that represents items like letters and numbers in a particular writing system. For example, lowercase-g is a character. When a particular character has been rendered, a shape now represents this character. This shape is called a glyph.

Chararcter encoding is a conversion table that maps character codes to glyph codes in the font. The character encoding used in the Java(tm) 2D API is Unicode. For more information on Unicode you can visit the site http://www.unicode.org.

Characters and glyphs do not have one-to-one correspondence. For example, lowercase-a acute can be represented by two glyphs: lowercase-a and acute. Another example is ligatures such as ligature -fi which is a single glyph representing two characters, f and i.

A Font is a collection of glyphs. A 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 the same as that used by java.awt.Font in JDK 1.1 and earlier releases. 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 face name is the one that should be used to specify fonts. This name signifies actual fonts in the host system, and does not identify font names with the shape of font characters as the logical font name does.

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.

isPlain(), isBold(), isItalic()

getSize

public int getSize()

Returns the point size of this Font, rounded to an integer. 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.

Returns:

the point size of this Font in 1/72 of an inch units.

JDK1.0

Returns the bounds of the characters indexed in the specified CharacterIterator in the specified FontRenderContext. The bounds is used to layout the String.

Parameters:

ci - the specified CharacterIterator

beginIndex - the initial offset in ci

limit - the end offset in ci

frc - the specified FontRenderContext

Returns:

a Rectangle2D that is the bounding box of the characters indexed in the specified CharacterIterator in the specified FontRenderContext.

Throws:

IndexOutOfBoundsException - if beginIndex is less than the start index of ci, or limit is greater than the end index of ci, or beginIndex is greater than limit
