About formats

PICT is a metafile graphics format created by Apple Computer as the native graphics format for the Macintosh, debuting alongside the original Mac in January 1984 and remaining central to Mac OS graphics until the transition to Mac OS X. PICT files record a series of QuickDraw operation codes (opcodes) that reproduce the image when replayed through the QuickDraw graphics engine: operations for drawing lines, arcs, rectangles, rounded rectangles, ovals, polygons, regions, text strings, and pixel maps (bitmaps). This opcode-based approach means PICT files are not simply pixel grids but rather programmatic descriptions of how to draw the image, combining resolution-independent vector elements with pixel data in a unified stream. The PICT 2 revision, introduced with the Macintosh II and Color QuickDraw in 1987, extended the format to handle 24-bit color, multiple pixel depths, extended color spaces, and embedded JPEG and PackBits compressed data. PICT was integral to the Macintosh user experience: system clipboard operations (Copy/Paste), screen capture, printing, and inter-application data exchange all used PICT as the common visual representation. One advantage is historical comprehensiveness: PICT files from the classic Mac era capture both the visual output and the drawing methodology of Mac applications, preserving not just the image but the QuickDraw operations that produced it — valuable for understanding the visual computing paradigm of early Macintosh software. The format's extensive use in desktop publishing during the DTP revolution of the late 1980s provides another dimension of historical importance. PICT files are readable by macOS Preview, ImageMagick, XnView, LibreOffice, and GraphicConverter.
Developer: Apple Computer
Initial release: 1984
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.
