About formats

WPG (WordPerfect Graphics) is a mixed vector/raster image format developed by WordPerfect Corporation and introduced with WordPerfect 5.0 on May 5, 1988. The format was designed to provide a native graphics capability for WordPerfect documents, supporting both vector drawing elements (lines, curves, polygons, text with font specifications, and filled shapes) and embedded raster images in a single file. WPG exists in two major versions: WPG1, which supports 1-bit and indexed color rasters up to 256 colors with optional run-length encoding compression, and WPG2, introduced later, which added true-color (24-bit) support, OLE object embedding, and enhanced vector capabilities. The vector portion of WPG files stores resolution-independent drawing commands that can be scaled and printed at any output device's native resolution, while the raster portion handles photographic and scanned content. During WordPerfect's peak market dominance in the late 1980s and early 1990s, WPG was one of the most commonly encountered graphics formats in business and legal document workflows, used for logos, diagrams, letterheads, and clip art. One advantage is the hybrid vector/raster capability: WPG could combine scalable line art with photographic imagery in a single file at a time when most formats handled only one or the other, making it practical for the mixed-content graphics typical of business documents. Continued accessibility is another strength — WPG files remain readable by LibreOffice, Corel's current software suite (which inherited WordPerfect), ImageMagick, XnView, and Inkscape, ensuring decades-old documents remain viewable.

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.
