About formats

PICT is a metafile graphics format created by Apple Computer as the native graphics format for the Macintosh, debuting alongside the original Mac in January 1984 and remaining central to Mac OS graphics until the transition to Mac OS X. PICT files record a series of QuickDraw operation codes (opcodes) that reproduce the image when replayed through the QuickDraw graphics engine: operations for drawing lines, arcs, rectangles, rounded rectangles, ovals, polygons, regions, text strings, and pixel maps (bitmaps). This opcode-based approach means PICT files are not simply pixel grids but rather programmatic descriptions of how to draw the image, combining resolution-independent vector elements with pixel data in a unified stream. The PICT 2 revision, introduced with the Macintosh II and Color QuickDraw in 1987, extended the format to handle 24-bit color, multiple pixel depths, extended color spaces, and embedded JPEG and PackBits compressed data. PICT was integral to the Macintosh user experience: system clipboard operations (Copy/Paste), screen capture, printing, and inter-application data exchange all used PICT as the common visual representation. One advantage is historical comprehensiveness: PICT files from the classic Mac era capture both the visual output and the drawing methodology of Mac applications, preserving not just the image but the QuickDraw operations that produced it — valuable for understanding the visual computing paradigm of early Macintosh software. The format's extensive use in desktop publishing during the DTP revolution of the late 1980s provides another dimension of historical importance. PICT files are readable by macOS Preview, ImageMagick, XnView, LibreOffice, and GraphicConverter.

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.
