About formats

XCF (eXperimental Computing Facility) is the native file format of GIMP (GNU Image Manipulation Program), named after the computing facility at UC Berkeley where Spencer Kimball and Peter Mattis originally developed GIMP as a student project, with the format introduced alongside GIMP 1.0 in 1998. XCF stores the complete editing state of a GIMP project: all layers with their positions, dimensions, opacity, and blending modes; layer masks; channels (including custom alpha channels); paths (vector shapes stored as Bezier curves); parasites (arbitrary named data attached to the image or individual layers); and the image's color profile, resolution, guides, and grid settings. The format supports 8-bit, 16-bit, and 32-bit floating-point precision per channel in RGB, grayscale, and indexed color modes, and uses a tile-based internal structure where the image is divided into 64x64 pixel tiles that are individually RLE-compressed. Each layer in an XCF file is stored independently with its own dimensions (layers can be larger or smaller than the canvas), enabling non-destructive editing workflows where source material is preserved at full resolution. One advantage is complete state preservation: XCF files save everything needed to resume editing exactly where you left off — every layer, mask, path, and setting — making them the essential working format for any multi-session GIMP project. The format's open specification is another strength: the XCF structure is fully documented and readable by GIMP, XnView, ImageMagick, and various programming libraries, ensuring project files remain accessible without vendor lock-in.
Initial release: 1998
LRF is the file format associated with Sony's BBeB (Broadband eBook) specification, jointly developed by Sony and Canon and introduced in 2004 with the Sony Librie EBR-1000EP — the world's first commercial E Ink e-reader. The format supports both reflowable text and fixed-layout page rendering, embedding fonts, images, vector graphics, and metadata within a compact binary container. LRF files use a block-based internal structure with object trees describing page layouts, text streams, image resources, and table of contents navigation. Sony's Reader devices and the companion desktop software (Sony Reader Library) served as the primary ecosystem for LRF content throughout the mid-2000s. A key advantage was its early adoption of high-quality font embedding and text rendering optimized specifically for E Ink displays, delivering a reading experience noticeably superior to many competing formats of the era. The format also supported bookmark synchronization, dictionary lookups, and annotations within the Sony Reader ecosystem. However, Sony officially discontinued BBeB/LRF support in 2010, migrating its Reader platform to the industry-standard EPUB format. Today LRF files are primarily encountered in personal ebook collections from that period and can be converted to modern formats using tools like Calibre. The format remains a historically significant milestone as the native format of the device category that launched the modern e-reader revolution.
