Rich Text Format
) As an example, the following RTF code would be rendered as follows: This is some bold text. Character encoding A standard RTF file can only consist of 7-bit ASCII characters, but can use escape sequences to encode other characters. The two character escapes are code page escapes and, starting with RTF 1.5, Unicode escapes. In a code page escape, two hexadecimal digits following a backslash and typewriter apostrophe denote a character taken from a Windows code page. For example, if the code page is set to Windows-1256, the sequence \'c8 will encode the Arabic letter ''bāʼ'' ب. It is also possible to specify a "Character Set" in the preamble of the RTF document and associate it to a header. For example, the preamble has the text \f3\fnil\fcharset128, then, in the body of the document, the text \f3\'bd\'f0 will represent the code point 0xbd 0xf0 from the Character Set 128 (which corresponds to the Shift-JIS code page), which encodes "金".

Windows Help
Microsoft WinHelp is a proprietary format for online help files that can be displayed by the Microsoft Help browser ''winhelp.exe'' or ''winhlp32.exe''. The file format is based on Rich Text Format (RTF). It remained a popular Help platform from Windows 3.0 through Windows XP. WinHelp was removed in Windows Vista purportedly to discourage software developers from using the obsolete format and encourage use of newer help formats. History * 1990 – WinHelp 1.0 shipped with Windows 3.0. * 1995 – WinHelp 4.0 shipped with Windows 95 / Windows NT. * 2006 – Microsoft announced its intentions to phase out WinHelp as a supported platform. WinHelp is not part of Windows Vista out of the box. WinHelp files come in 16 bit and 32 bit types. Vista treats these files types differently. When starting an application that uses the 32 bit .hlp format, Windows warns that the format is no longer supported. A downloadable viewer for 32 bit .hlp files is available from the Microsoft Download Center. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Office Open XML
Office Open XML (also informally known as OOXML) is a zipped, XML-based file format developed by Microsoft for representing spreadsheets, charts, presentations and word processing documents. Ecma International standardized the initial version as ECMA-376. ISO and IEC standardized later versions as ISO/IEC 29500. Microsoft Office 2010 provides read support for ECMA-376, full support for ISO/IEC 29500 Transitional, and read support for ISO/IEC 29500 Strict. Microsoft Office 2013 and later fully support ISO/IEC 29500 Strict, but don't use it as the default file format because of backwards compatibility concerns. Background In 2000, Microsoft released an initial version of an XML-based format for Microsoft Excel, which was incorporated in Office XP. In 2002, a new file format for Microsoft Word followed. The Excel and Word formats—known as the Microsoft Office XML formats—were later incorporated into the 2003 release of Microsoft Office. Microsoft announced in November 2005 ...

Smart Tag (Microsoft)
Smart tags are an early selection-based search feature, found in later versions of Microsoft Word and beta versions of the Internet Explorer 6 web browser, by which the application recognizes certain words or types of data and converts it to a hyperlink. It is also included in other Microsoft Office programs as well as Visual Web Developer. Selection-based search allows a user to invoke an online service from any other page using only the mouse. Microsoft had initially intended the technology to be built into its Windows XP operating system but changed its plans due to public criticism. Overview Smart tags are integrated in instances where a user might benefit from an added formatting assistance and it is part of Microsoft's control technology. It is presented as a special shortcut menu, listing options such as paste, AutoCorrect, date, Person Name, and addresses, among others that flag entered information, accordingly. Smart tags work through ''actions'' and ''recognizers''. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enhanced Metafile
Windows Metafile (WMF) is an image file format originally designed for Microsoft Windows in the 1990s. The original Windows Metafile format was not device-independent (though could be made more so with placement headers) and may contain both vector graphics and bitmap components. It acts in a similar manner to Scalable Vector Graphics, SVG files. WMF files were later superseded by Enhanced Metafiles (EMF files) which did provide for device-independence. EMF files were then themselves enhanced via EMF+ files. Essentially, a metafile stores a list of records consisting of drawing commands, property definitions and graphics objects to display an image on screen. The drawing commands used are closely related to the commands of the Graphics Device Interface (GDI) Application programming interface, API used for drawing in Microsoft Windows. There are three major types of metafiles – a WMF is a 16-bit format introduced in Windows 3.0. It is the native vector graphics, vector format for ...

JPEG
JPEG ( ) is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG typically achieves 10:1 compression with little perceptible loss in image quality. Since its introduction in 1992, JPEG has been the most widely used image compression standard in the world, and the most widely used digital image format, with several billion JPEG images produced every day as of 2015. The term "JPEG" is an acronym for the Joint Photographic Experts Group, which created the standard in 1992. JPEG was largely responsible for the proliferation of digital images and digital photos across the Internet, and later social media. JPEG compression is used in a number of image file formats. JPEG/Exif is the most common image format used by digital cameras and other photographic image capture devices; along with JPEG ...

Portable Network Graphics
Portable Network Graphics (PNG, officially pronounced , colloquially pronounced ) is a raster-graphics file format that supports lossless data compression. PNG was developed as an improved, non-patented replacement for Graphics Interchange Format (GIF) — unofficially, the initials PNG stood for the recursive acronym "PNG's not GIF". PNG supports palette-based images (with palettes of 24-bit RGB or 32-bit RGBA colors), grayscale images (with or without an alpha channel for transparency), and full-color non-palette-based RGB or RGBA images. The PNG working group designed the format for transferring images on the Internet, not for professional-quality print graphics; therefore non-RGB color spaces such as CMYK are not supported. A PNG file contains a single image in an extensible structure of ''chunks'', encoding the basic pixels and other information such as textual comments and integrity checks documented in RFC 2083. PNG files use the file extension PNG or png and hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unicode
Unicode, formally The Unicode Standard,The formal version reference is is an information technology Technical standard, standard for the consistent character encoding, encoding, representation, and handling of Character (computing), text expressed in most of the world's writing systems. The standard, which is maintained by the Unicode Consortium, defines as of the current version (15.0) 149,186 characters covering 161 modern and historic script (Unicode), scripts, as well as symbols, emoji (including in colors), and non-visual control and formatting codes. Unicode's success at unifying character sets has led to its widespread and predominant use in the internationalization and localization of computer software. The standard has been implemented in many recent technologies, including modern operating systems, XML, and most modern programming languages. The Unicode character repertoire is synchronized with Universal Coded Character Set, ISO/IEC 10646, each being code-for-code id ...

Bitmap
In computing, a bitmap is a mapping from some domain (for example, a range of integers) to bits. It is also called a bit array A bit array (also known as bitmask, bit map, bit set, bit string, or bit vector) is an array data structure that compactly stores bits. It can be used to implement a simple set data structure. A bit array is effective at exploiting bit-level ... or bitmap index. As a noun, the term "bitmap" is very often used to refer to a particular bitmapping application: the pix-map, which refers to a map of pixels, where each one may store more than two colors, thus using more than one bit per pixel. In such a case, the domain in question is the array of pixels which constitute a digital graphic output device (a screen or monitor). In some contexts, the term ''bitmap'' implies one bit per pixel, whereas ''pixmap'' is used for images with multiple bits per pixel. A bitmap is a type of computer storage, memory organization or image file format used to store dig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Font Embedding
Font embedding is the inclusion of font files inside an electronic document. Font embedding is controversial because it allows licensed fonts to be freely distributed. History Font embedding has been possible with Portable Document Format (PDF), Microsoft Word for Windows and some other applications for many years. LibreOffice supports font embedding since version 4.1 in its Writer, Calc and Impress applications. In word processors Microsoft Word for Windows has permitted font embedding in some document formats since Word 97 (such as .doc or .rtf). But this feature does not work correctly in some Word versions. LibreOffice supports font embedding since version 4.1. This feature is available for the word processor LibreOffice Writer, the spreadsheet application LibreOffice Calc, and the presentation application LibreOffice Impress. Both OpenOffice.org and LibreOffice support font embedding in the PDF export feature. Font embedding in word processors is not widely supported nor i ...

OS/2
OS/2 (Operating System/2) is a series of computer operating systems, initially created by Microsoft and IBM under the leadership of IBM software designer Ed Iacobucci. As a result of a feud between the two companies over how to position OS/2 relative to Microsoft's new Windows 3.1 operating environment, the two companies severed the relationship in 1992 and OS/2 development fell to IBM exclusively. The name stands for "Operating System/2", because it was introduced as part of the same generation change release as IBM's " Personal System/2 (PS/2)" line of second-generation personal computers. The first version of OS/2 was released in December 1987 and newer versions were released until December 2001. OS/2 was intended as a protected-mode successor of PC DOS. Notably, basic system calls were modeled after MS-DOS calls; their names even started with "Dos" and it was possible to create "Family Mode" applications – text mode applications that could work on both systems.

PICT
The Picts were a group of peoples who lived in what is now northern and eastern Scotland (north of the Firth of Forth) during Late Antiquity and the Early Middle Ages. Where they lived and what their culture was like can be inferred from early medieval texts and Pictish stones. Their Latin name, , appears in written records from the 3rd to the 10th century. Early medieval sources report the existence of a distinct Pictish language, which today is believed to have been an Insular Celtic language, closely related to the Brittonic spoken by the Britons who lived to the south. Picts are assumed to have been the descendants of the Caledonii and other Iron Age tribes that were mentioned by Roman historians or on the world map of Ptolemy. The Pictish kingdom, often called Pictland in modern sources, achieved a large degree of political unity in the late 7th and early 8th centuries through the expanding kingdom of Fortriu, the Iron Age Verturiones. By the year 900, the resulting Pict ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
