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 and Logical Fonts The Java Platform distinguishes between two kinds of fonts: physical fonts and logical fonts. 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 Faces and Names 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 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 and TextAttribute 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.
The Ubuntu font family are a set of matching new libre/open fonts. The development is being funded by Canonical on behalf the wider Free Software community and the Ubuntu project. The technical font design work and implementation is being undertaken by Dalton Maag.
Both the final font Truetype/OpenType files and the design files used to produce the font family are distributed under an open licence and you are expressly encouraged to experiment, modify, share and improve. The typeface is sans-serif, uses OpenType features and is manually hinted for clarity on desktop and mobile computing screens.
The Ubuntu font family is a sans-serif typeface family available in 22 styles plus a variable font with adjustable weight and width axes. Its fixed-width companion, Ubuntu Mono, comes in 8 styles and a variable font with an adjustable weight axis.
You can also specify a default line height using the object syntax, which allows you to also provide default letter-spacing and font-weight values. You can do this using a tuple of the form [fontSize, lineHeight?, letterSpacing?, fontWeight? ].
Atkinson Hyperlegible font is named after Braille Institute founder, J. Robert Atkinson. What makes it different from traditional typography design is that it focuses on letterform distinction to increase character recognition, ultimately improving readability. We are making it free for anyone to use!
Adherence to font size, type density, line spacing, and text color requirements is necessary to ensure readability and fairness. Although font requirements apply to all attachments, they are most important and most heavily scrutinized in attachments with page limits.
A baptismal font is an ecclesiastical architectural element, which serves as a receptacle for baptismal water used for baptism, as a part of Christian initiation for both rites of infant and adult baptism.[1]
The earliest western fonts are found in the Catacombs of Rome. The fonts of many western Christian denominations that practice infant baptism are designed for baptisms using a non-immersive method, such as aspersion (sprinkling) or affusion (pouring). The simplest of these fonts has a pedestal with a holder for a basin of water. The materials vary greatly consisting of carved and sculpted marble, wood, or metal in different shapes. Many fonts are in octagonal shape, as a reminder of the new creation and as a connection to the Old Testament practice of circumcision, which traditionally occurs on the eighth day.[2] Some fonts are three-sided as a reminder of the Holy Trinity to represent the unity of Father, Son, and Holy Spirit as three persons in one.
Fonts are often placed at or near the entrance to a church's nave to remind believers of their baptism as they enter the church to pray, since the rite of baptism served as their initiation into the Church. In Lutheran churches, the baptismal font may be located in the chancel near the altar to serve as a testament to Lutheran sacramental theology.[3]In many churches of the Middle Ages and Renaissance, there was a special chapel or even a separate building for housing the baptismal fonts, called a baptistery. Both fonts and baptisteries were often octagonal (eight-sided), octagonal fonts becoming more common from the 13th century and the norm from the 14th century.[4] Saint Ambrose wrote that fonts and baptisteries were octagonal "because on the eighth day,[a] by rising, Christ loosens the bondage of death and receives the dead from their graves".[6][5]Saint Augustine similarly described the eighth day as "everlasting... hallowed by the resurrection of Christ".[6][7]
The quantity of water is usually small. There are some fonts where water pumps, a natural spring, or gravity keeps the water moving to mimic the moving waters of a stream. This visual and audible image communicates a "living waters" aspect of baptism. Some liturgical church bodies use consecrated holy water for the purpose of baptism, while others will use water straight out of the tap to fill the font.[8] A special silver vessel called a ewer can be used to fill the font. Most baptismal fonts have covers to prevent water from evaporating and to protect baptismal water against contamination.
In certain regions of England, a common historic type of font design can be identified. In South East England the "Aylesbury font" can be seen in several churches in Buckinghamshire and the surrounding area. These fonts, which date from the late 12th Century around the years 1170 to 1190, are typically chalice-shaped, ornately carved around the rim with fluting below, and are considered fine examples of English Norman architecture. They are named after the font found in the Church of St Mary the Virgin, Aylesbury.[9][10] Other identifiable types include the Early English "table-top" font, also found in Buckinghamshire; the "Bodmin font" in Cornwall, the "Seven Sacrament fonts" in East Anglia; and "Chalice fonts" in Herefordshire.[11]
