About formats

WPG (WordPerfect Graphics) is a mixed vector/raster image format developed by WordPerfect Corporation and introduced with WordPerfect 5.0 on May 5, 1988. The format was designed to provide a native graphics capability for WordPerfect documents, supporting both vector drawing elements (lines, curves, polygons, text with font specifications, and filled shapes) and embedded raster images in a single file. WPG exists in two major versions: WPG1, which supports 1-bit and indexed color rasters up to 256 colors with optional run-length encoding compression, and WPG2, introduced later, which added true-color (24-bit) support, OLE object embedding, and enhanced vector capabilities. The vector portion of WPG files stores resolution-independent drawing commands that can be scaled and printed at any output device's native resolution, while the raster portion handles photographic and scanned content. During WordPerfect's peak market dominance in the late 1980s and early 1990s, WPG was one of the most commonly encountered graphics formats in business and legal document workflows, used for logos, diagrams, letterheads, and clip art. One advantage is the hybrid vector/raster capability: WPG could combine scalable line art with photographic imagery in a single file at a time when most formats handled only one or the other, making it practical for the mixed-content graphics typical of business documents. Continued accessibility is another strength — WPG files remain readable by LibreOffice, Corel's current software suite (which inherited WordPerfect), ImageMagick, XnView, and Inkscape, ensuring decades-old documents remain viewable.
Initial release: 1988
SNB is a proprietary ebook format developed by Shanghai Nutshell Electronics, a subsidiary of Shanda Interactive Entertainment, for the Bambook e-reader launched in August 2010. The format is structurally based on EPUB principles, packaging HTML content, CSS styling, images, and metadata within a compressed archive, but uses a proprietary container that restricts native playback to Bambook devices and associated software. Shanda designed the Bambook and its SNB ecosystem as an integrated reading platform tied to the Cloudary literature portal (later rebranded as China Literature), one of China's largest online publishing networks hosting millions of web novels and serialized fiction. The format supported reflowable text, chapter navigation, bookmarks, and basic typographic controls suited to Chinese-language content display. One advantage was tight integration with Shanda's massive content catalog, providing readers instant access to an enormous library of Chinese-language literature directly through the device. The Bambook was initially offered at a heavily subsidized price point, using the content ecosystem to drive revenue — a model that preceded similar strategies by other e-reader manufacturers. While the Bambook hardware line was eventually discontinued as the Chinese market shifted toward tablet-based reading apps, SNB files from that era can be converted to standard formats using tools like Calibre with appropriate plugins. The format represents an interesting case study in platform-specific ebook ecosystems within the Chinese digital publishing landscape.
