Transformation of text is strategies to perform geometric transformations on text (reversals, 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 characters, those that have been reflected in a vertical line (i.e., flipped horizontally); *Inverted characters, those that have been reflected on a horizontal line (i.e., flipped vertically, only one letter has been done this way); *Turned characters, those that have been rotated 180 degrees and thus appear upside-down (this is the most common); *Sideways characters, those that have been rotated 90 degrees counterclockwise (generally the least supported, and used only for a handful of vowels in the Uralic Phonetic Alphabet system). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「transformation of text」の詳細全文を読む スポンサード リンク
