About formats

KWD is the native document format of KWord, the word processor component of KOffice (later renamed Calligra Suite), developed by the KDE community with its first stable release in KOffice 1.0 in 2000. KWord distinguished itself from other word processors through a frame-based layout model where text, images, and other content existed in independent frames that could be positioned freely on the page, similar to desktop publishing applications — a departure from the linear text-flow approach used by most word processors. KWD files store document content in a compressed XML format that describes the frame hierarchy, text content with formatting markup, paragraph styles, page dimensions, headers, footers, and embedded media. The format uses a ZIP container packaging the XML document alongside any referenced images and resources. One advantage was the flexible frame-based layout — users could position text and image frames independently on the page, enabling newsletter-style layouts and creative document designs without switching to a dedicated DTP application. The open XML structure is another benefit, making KWD files transparent and accessible to automated processing. KWord was included in several Linux distributions as part of the KDE desktop environment during the 2000s. The project was eventually discontinued in favor of Calligra Words, which adopted the ODF standard. KWD files can be opened with legacy KOffice installations or converted through document conversion tools.

Initial release: 2000
SIXEL (Six Pixel) is a bitmap graphics encoding format created by Digital Equipment Corporation (DEC) in 1983 for rendering images on character-cell printers and video terminals. The name derives from the encoding's fundamental unit: a column of six pixels represented by a single ASCII character. Each printable character in the sixel data stream (ASCII 63-126) encodes a 6-pixel vertical column, with the character's binary value determining which pixels are on or off. Color is specified through register-based palette control: a Select Color Sequence assigns an HLS or RGB color value to a numbered register, and subsequent sixel characters use that color until another register is selected. The encoding supports raster attributes for specifying pixel aspect ratio and image dimensions, repeat sequences (! followed by a count and character) for run-length compression of identical columns, and $ (carriage return) and - (new line) for navigating the sixel grid. DEC implemented SIXEL support in their VT240, VT241, VT330, and VT340 terminals, as well as multiple printer models. One advantage of the SIXEL encoding is its ASCII-clean nature: the data stream consists entirely of printable characters and standard control sequences, meaning SIXEL graphics can be transmitted through any text-based communication channel — serial terminals, SSH sessions, telnet connections — without requiring binary-safe transport or protocol modifications. The format's modern renaissance provides another remarkable dimension: after decades of obscurity, SIXEL support has been implemented in numerous contemporary terminal emulators, enabling inline image display in command-line workflows. SIXEL output can be generated by ImageMagick, libsixel, chafa, and various plotting libraries.
Initial release: 1983
