About formats

RGBO is a raw pixel data format designation used by ImageMagick, the open-source image processing suite first released in 1990, representing images as a flat sequence of Red, Green, Blue, and Opacity (inverted alpha) sample values with no header, container, or compression. The RGBO channel ordering specifies that the fourth channel is opacity rather than alpha — where alpha represents transparency (0 = transparent, max = opaque), opacity represents the inverse (0 = opaque, max = transparent). This distinction matters in compositing pipelines where the mathematical convention for the fourth channel varies between systems: some compositing models work with alpha (transparency), while older conventions including portions of ImageMagick's internal processing historically used opacity. RGBO files contain raw sample data at a user-specified bit depth (8-bit, 16-bit, or floating-point per channel), with pixels stored in scanline order. Because there is no header, the image dimensions, bit depth, and endianness must be specified externally when reading the file — typically via ImageMagick command-line arguments. One advantage is direct compatibility with processing pipelines that use the opacity convention: RGBO eliminates the need for channel inversion when interfacing with systems that expect opacity rather than alpha, preventing subtle compositing errors that occur when transparency conventions are mixed. The format's raw-data nature provides another practical benefit — with no encoding overhead, RGBO data can be memory-mapped, processed with SIMD instructions, or piped between processes with minimal latency. RGBO is primarily used within ImageMagick processing chains and can be converted to any other format using ImageMagick's extensive format support.
Initial release: 1990
PAM (Portable Arbitrary Map) is a raster image format added to the Netpbm family around the year 2000 by Bryan Henderson, the maintainer of Netpbm, as a generalization that unifies and extends the original PBM, PGM, and PPM formats. Where the classic Netpbm formats each handle a specific image type (PBM for bilevel, PGM for grayscale, PPM for color), PAM provides a single format that can represent any combination of channels, bit depths, and image types through a flexible ASCII header. The PAM header uses keyword-value pairs: WIDTH, HEIGHT, DEPTH (number of channels), MAXVAL (maximum sample value, up to 65535), and TUPLTYPE (a string identifying the image type — BLACKANDWHITE, GRAYSCALE, RGB, GRAYSCALE_ALPHA, RGB_ALPHA, or custom types). After the header, pixel data is stored in binary, with each sample occupying one or two bytes depending on MAXVAL. PAM's key innovation over its predecessors is native alpha channel support: GRAYSCALE_ALPHA (2-channel) and RGB_ALPHA (4-channel) tupletypes provide transparency without requiring a separate mask file, something the original PBM/PGM/PPM formats could not express. One advantage is format unification: a single PAM-reading implementation handles monochrome, grayscale, color, and alpha-augmented images, eliminating the need for separate parsers for each Netpbm variant. The extensible TUPLTYPE mechanism provides another practical strength — custom channel configurations (multispectral, depth + color, or any application-specific arrangement) can be represented and labeled without modifying the format specification. PAM is supported by Netpbm tools, ImageMagick, GIMP, and programming libraries that process the Netpbm family.
Initial release: 2000
