Transformation Of Text
Transformations of text are strategies to perform geometric transformations on text (reversal, rotations, etc.), particularly in systems that do not natively support transformation, such as HTML, seven-segment displays and plain text. Implementation Many systems, such as HTML, seven-segment displays and plain text, do not support transformation of text. In the case of HTML, this limitation in display may eventually be addressed through standard cascading style sheets (CSS), since proposed specifications for CSS3 include rotation for block elements. In the meantime, several ways of producing the visual effects of text transformations have come into use. The most common of these transformations are rotation and reflection. Unicode supports a variety of characters that resemble transformed characters, primarily for various forms of phonetic transcription. Each of these character names indicates what kind of transformation the characters have undergone: *Reversed charact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transformation (geometry)
In mathematics, a geometric transformation is any bijection of a set to itself (or to another such set) with some salient geometrical underpinning, such as preserving distances, angles, or ratios (scale). More specifically, it is a function whose domain and range are sets of points – most often a real coordinate space, \mathbb^2 or \mathbb^3 – such that the function is bijective so that its inverse exists. The study of geometry may be approached by the study of these transformations, such as in transformation geometry. Classifications Geometric transformations can be classified by the dimension of their operand sets (thus distinguishing between, say, planar transformations and spatial transformations). They can also be classified according to the properties they preserve: * Displacements preserve distances and oriented angles (e.g., translations); * Isometries preserve angles and distances (e.g., Euclidean transformations); * Similarities preserve angles and ratios ...

Interpunct
An interpunct , also known as an interpoint, middle dot, middot, centered dot or centred dot, is a punctuation mark consisting of a vertically centered dot used for interword separation in Classical Latin. ( Word-separating spaces did not appear until some time between 600 and 800 CE.) It appears in a variety of uses in some modern languages. The multiplication dot or "dot operator" is frequently used in mathematical and scientific notation, and it may differ in appearance from the interpunct. In written language Various dictionaries use the interpunct (in this context, sometimes called a hyphenation point) to indicate where to split a word and insert a hyphen if the word doesn't fit on the line. There is also a separate Unicode character, . English In British typography, the space dot was once used as the formal decimal point. Its use was advocated by laws and can still be found in some UK-based academic journals such as ''The Lancet''. When the pound sterling was de ...

Letterlike Symbols (Unicode Block)
Letterlike Symbols is a Unicode block containing 80 characters which are constructed mainly from the glyphs of one or more letters. In addition to this block, Unicode includes full styled mathematical alphabets, although Unicode does not explicitly categorize these characters as being "letterlike." Symbols Glyph variants Variation selectors may be used to specify chancery (U+FE00) vs roundhand (U+FE01) forms, if the font supports them: The remainder of the set is at Mathematical Alphanumeric Symbols. Block Emoji The Letterlike Symbols block contains two emoji: U+2122 and U+2139. The block has four standardized variants defined to specify emoji-style (U+FE0F VS16) or text presentation (U+FE0E VS15) for the two emoji, both of which default to a text presentation. History The following Unicode-related documents record the purpose and process of defining specific characters in the Letterlike Symbols block: See also * Greek in Unicode * Latin script in Un ...

Turned H
Turned H (uppercase: Ɥ, lowercase: ɥ) is an additional letter of the Latin alphabet, based on a turned form of H. It is used in the Dan language in Liberia. Its lowercase form is used in the International Phonetic Alphabet to represent the voiced labial–palatal approximant. It was also historically used in the Abaza, Abkhaz, and the Vassali Maltese alphabet. Usage An early usage of turned h appeared in Benjamin Franklin's phonetic alphabet where it represented � During Latinisation, the letter would appear in the Abaza Latin alphabet of 1932 where it denoted the sound ͡ɕ and in the Abkhaz Latin alphabet of 1924 where it denoted the sound ͡ʃʰ The letter also appeared in the Vassalli Maltese alphabet, and the Metelko alphabet for Slovene, where it stood for the sound ͡ʃ In the Metelko alphabet, Maltese, Abaza, and Abkhaz languages, the letter had a capital form Ч, identical to the Cyrillic letter Che. This letter was also used in the first version o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Letter (alphabet)
In a writing system, a letter is a grapheme that generally corresponds to a phoneme—the smallest functional unit of speech—though there is rarely total one-to-one correspondence between the two. An alphabet is a writing system that uses letters. Definition and usage A letter is a type of grapheme, the smallest functional unit within a writing system. Letters are graphemes that broadly correspond to phonemes, the smallest functional units of sound in speech. Similarly to how phonemes are combined to form spoken words, letters may be combined to form written words. A single phoneme may also be represented by multiple letters in sequence, collectively called a ''multigraph (orthography), multigraph''. Multigraphs include ''digraphs'' of two letters (e.g. English ''ch'', ''sh'', ''th''), and ''trigraphs'' of three letters (e.g. English ''tch''). The same letterform may be used in different alphabets while representing different phonemic categories. The Latin H, Greek eta , an ...

Oblique Type
Oblique type is a form of type that slants slightly to the right, used for the same purposes as italic type. Unlike italic type, however, it does not use different glyph shapes; it uses the same glyphs as roman type, except slanted. Oblique and italic type are technical terms to distinguish between the two ways of creating slanted font styles; oblique designs may be labelled italic by companies selling fonts or by computer programs. Oblique designs may also be called slanted or sloped roman styles. Oblique fonts, as supplied by a font designer, may be simply slanted, but this is often not the case: many have slight corrections made to them to give curves more consistent widths, so they retain the proportions of counter (typography), counters and the thick-and-thin quality of strokes from the regular design. Type designers have described oblique type as less organic and calligraphic than italics, which in some situations may be preferred. Contemporary type designer Jeremy Tankard s ...

Latin Alpha
Latin alpha (majuscule: Ɑ, minuscule: ɑ), script a, or single-story a is a letter of the Latin alphabet based on a handwritten form of lowercase a, and which is commonly typeset with the Greek lowercase alpha (α). Usage Although is normally just an allograph of , there are instances in which the two letters are distinguished: * In the International Phonetic Alphabet, represents an open back unrounded vowel, while represents an open front unrounded vowel. It has the shape of a script-a. * Also in the General Alphabet of Cameroon Languages, usually represents an open back unrounded vowel, while represents an open front unrounded vowel. The former is used in the orthographies of several languages of Cameroon, including: ** Feʼfeʼ ** Mbembe ** Mbo (?): but not Akoose, though it does have phonemes /aa/ and /ɑɑ/; nor Bakaka. ** in some languages, the script-a form (also called literacy form) of the letter , with the lowercase much like the IPA , is used and should n ...

Italic Type
In typography, italic type is a cursive font based on a stylised form of calligraphic handwriting. Along with blackletter and roman type, it served as one of the major typefaces in the history of Western typography. Owing to the influence from calligraphy, italics normally slant slightly to the right, ''like so''. Different glyph shapes from roman type are usually usedanother influence from calligraphyand upper-case letters may have Swash (typography), swashes, flourishes inspired by ornate calligraphy. Historically, italics were a distinct style of type used entirely separately from roman type, but they have come to be used in conjunction—most fonts now come with a roman type and an oblique type, oblique version (generally called "italic" though often not true italics). In this usage, italics are a way to emphasise key points in a printed text, to identify many types of creative works, to cite foreign words or phrases, or, when quoting a speaker, a way to show which w ...

Involution (mathematics)
In mathematics, an involution, involutory function, or self-inverse function is a function that is its own inverse, : for all in the domain of . Equivalently, applying twice produces the original value. General properties Any involution is a bijection. The identity map is a trivial example of an involution. Examples of nontrivial involutions include negation (), reciprocation (), and complex conjugation () in arithmetic; reflection, half-turn rotation, and circle inversion in geometry; complementation in set theory; and reciprocal ciphers such as the ROT13 transformation and the Beaufort polyalphabetic cipher. The composition of two involutions and is an involution if and only if they commute: . Involutions on finite sets The number of involutions, including the identity involution, on a set with elements is given by a recurrence relation found by Heinrich August Rothe in 1800: : a_0 = a_1 = 1 and a_n = a_ + (n - 1)a_ for n > 1.

Leet
Leet (or "1337"), also known as eleet or leetspeak, or simply hacker speech, is a system of modified spellings used primarily on the Internet. It often uses character replacements in ways that play on the similarity of their glyphs via reflection or other resemblance. Additionally, it modifies certain words on the basis of a system of suffixes and alternative meanings. There are many dialects or linguistic varieties in different online communities. The term "leet" is derived from the word '' elite'', used as an adjective to describe skill or accomplishment, especially in the fields of online gaming and computer hacking. The leet lexicon includes spellings of the word as ''1337'' or ''leet''. History Leet originated within bulletin board systems (BBS) in the 1980s,Mitchell.An Explanation of l33t Speak. where having "elite" status on a BBS allowed a user access to file folders, games, and special chat rooms.
