About formats

PWP is a proprietary image format used by Seattle FilmWorks (later renamed PhotoWorks) for their internet-based photo delivery service in the mid-to-late 1990s. When customers mailed film rolls to Seattle FilmWorks for developing, the company offered a Pictures Online service that let users download their scanned photos through a dial-up internet connection. PWP files were the format used for these online downloads, containing JPEG-compressed image data wrapped in a proprietary container with additional metadata for the PhotoWorks viewing software. The format was intentionally tied to Seattle FilmWorks' proprietary desktop viewer application (PhotoMail), which customers needed to install to view and manage their downloaded photos. PWP represented one of the earliest attempts at digital photo delivery — bridging the gap between traditional film processing and the emerging internet, at a time when most consumers had no other way to get digital copies of their photographs. One advantage of the PWP format's historical context is that it preserves scanned film images from a transitional era when few consumers owned digital cameras or scanners, making PWP files potentially the only digital record of photographs from that period. The format's JPEG-based internal structure is another practical consideration: despite the proprietary wrapper, the underlying image data uses standard JPEG compression, and tools like ImageMagick, XnView, and dedicated PWP converters can extract the images for viewing in any modern application.

PCT (also known as PICT) is a metafile graphics format originally developed by Apple Computer and introduced alongside the original Macintosh in January 1984. PCT files can contain both vector drawing commands and raster bitmap data, encoded as a sequence of QuickDraw drawing operations — the same graphics primitives used by the Macintosh operating system for all on-screen rendering. The format evolved through two major versions: PICT 1, which recorded basic QuickDraw operations (lines, rectangles, ovals, text, 1-bit bitmaps) in a compact format suitable for the original Macintosh's limited memory, and PICT 2, introduced with Color QuickDraw in 1987, which extended the format to support 24-bit color, multiple color spaces, and embedded JPEG-compressed data. PCT files begin with a 512-byte header (originally used for resource fork information), followed by the picture size, bounding rectangle, and a sequence of opcodes that define the drawing operations. During the Macintosh's commercial ascendancy, PICT was the universal graphics interchange format on Mac OS — the system clipboard used PICT for all graphical copy/paste operations, and most Mac applications could import and export the format. One advantage is the hybrid vector/raster nature: PCT files from the QuickDraw era preserve both scalable drawing commands and pixel data in a single format, enabling resolution-independent output for the vector portions. PICT's historical significance as the native Mac graphics format throughout the classic Mac OS era (1984-2001) provides another dimension. PCT files remain readable by Preview) on macOS, ImageMagick, XnView, LibreOffice, and GIMP.
