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
PGM (Portable Graymap) is the grayscale member of the Netpbm image format family, created by Jef Poskanzer in 1988 as part of the Pbmplus toolkit for Unix systems. PGM stores single-channel intensity images where each pixel holds a gray value from 0 (black) to a user-specified maximum (typically 255 for 8-bit or 65535 for 16-bit). The format exists in ASCII (magic number P2), where pixel values are written as decimal text numbers separated by whitespace, and binary (magic number P5), where values are stored as raw bytes. Both variants begin with a header specifying the magic number, width, height, and maximum gray value. PGM was designed as the grayscale intermediate in Netpbm's convert-process-convert pipeline philosophy: source images from any format are converted to PGM, processed using Netpbm's extensive command-line tool library, then converted to the target format. One advantage is format transparency — the ASCII variant makes image data directly readable by humans and trivially processable by text tools like awk and grep, invaluable for debugging and education. The scientific and computer vision community's adoption is another strength: PGM's straightforward single-channel representation makes it a natural format for image analysis algorithms, and many academic papers and course materials use PGM examples. The format is supported by ImageMagick, GIMP, and countless image processing libraries, and remains standard input for many research tools and benchmarks.
