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
PNM (Portable Any Map) is an umbrella designation within the Netpbm family that encompasses all three classic portable map formats: PBM (Portable BitMap for monochrome), PGM (Portable GrayMap for grayscale), and PPM (Portable PixMap for color). Created by Jef Poskanzer in 1988 as part of the Pbmplus toolkit, PNM is not a distinct format with its own magic number but rather a collective name indicating that any of the three underlying formats may be used. When software reads a PNM file, it examines the magic number (P1/P4 for PBM, P2/P5 for PGM, P3/P6 for PPM) and processes accordingly; when software writes a PNM file, it selects the most appropriate subformat based on the image content. This convention allows Netpbm processing pipelines to pass images between tools without requiring the user to track which specific format is in use — every tool in the chain accepts PNM input and produces PNM output, with the actual format chosen automatically. The Netpbm toolkit provides hundreds of command-line utilities for image manipulation: scaling, rotation, color adjustment, compositing, format conversion, quantization, and analysis — all operating on PNM as the common interchange format. One advantage is pipeline composability: Netpbm tools can be chained with Unix pipes (e.g., pnmflip | pnmscale | ppmquant | ppmtogif) to build complex image processing operations from simple primitives, following the Unix philosophy of small, focused tools. The format family's cross-platform availability and language support is another strength — virtually every image processing library in every programming language can read and write PNM variants. PNM files are supported by ImageMagick, GIMP, and all major image tools.
