About formats

PFA (Printer Font ASCII) is one of two file representations of Adobe's PostScript Type 1 font format, introduced in 1984 as part of the PostScript page description language. A PFA file contains the complete font program as plain ASCII text — the clear-text header with font name, encoding array, and metrics, followed by a hex-encoded encrypted section (eexec) holding the actual glyph outlines described as cubic Bezier curves with stem hints. Because every byte is represented in printable ASCII characters, PFA files are roughly twice the size of their PFB binary counterparts, but they can be transmitted through any text-safe channel and edited in a standard text editor. PFA became the standard Type 1 distribution format on Unix and Linux systems, where binary font formats were less convenient for PostScript printer pipelines. A key advantage is universal text compatibility — PFA files pass cleanly through email systems, FTP text-mode transfers, and version control without corruption from character encoding transformations. The readable structure also benefits font developers, who can inspect header values and encoding declarations directly. Type 1 fonts in PFA form powered the desktop publishing revolution of the late 1980s and 1990s, with Adobe's font library and the Apple LaserWriter printer establishing PostScript typography as the professional standard. Although OpenType has superseded Type 1 for new font development, PFA files remain in active use within legacy publishing workflows and PostScript/PDF production systems.

XV is an alternate file extension for the VIFF (Visualization Image File Format) developed by Khoral Research as part of the Khoros scientific image processing environment, which originated at the University of New Mexico around 1990. The .xv extension and the .viff extension refer to the same underlying format — a container with a 1024-byte header encoding image dimensions, data type (from single-bit to double-precision float and complex numbers), color space, band count, and optional spatial location metadata, followed by color map data and pixel values. The XV extension became common on systems where Khoros was installed alongside other X Window System tools, and in some research communities .xv was preferred over .viff as a shorter alternative. Khoros itself was a pioneering visual programming system where scientists assembled image processing pipelines by wiring together processing nodes in a graphical canvas — an approach that predated and influenced similar environments in MATLAB, LabVIEW, and commercial remote sensing packages. One advantage of the VIFF/XV format is its ability to store data at scientific precision levels — floating-point and complex number pixel values preserve measurement accuracy that would be lost in photographic formats limited to 8-bit or 16-bit integers, making it valuable for spectral analysis, computational physics output, and satellite imagery. The multi-band architecture provides another strength, allowing a single file to hold dozens of spectral channels from multispectral or hyperspectral sensors without splitting data across multiple files. XV files are supported by ImageMagick and can be converted to modern image formats for visualization or publication.

Frequently Asked Questions

Why convert PFA to XV?

XV format creates compact thumbnail images — useful for generating quick visual previews of PFA font glyphs in Unix-based imaging workflows.

How to open XV?

XV files are read by the xv image viewer, ImageMagick, and Khoros/VisiQuest tools. They can also be converted to PNG or JPEG for wider use.

Is XV a common format?

XV is niche — mainly used by the xv image viewer and related Unix tools. For general thumbnails, JPEG or PNG are more practical.

What resolution does XV produce?

XV images are typically small, thumbnail-sized. The output dimensions depend on the content of the source PFA font rendering.

Can I generate these from any OS?

Yes. The conversion runs in your browser — produce XV files from Windows, macOS, or Linux without the xv viewer.
