PFA to WBMP Converter

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 Although OpenType has superseded Type 1 for new font development, PFA files remain in active use within legacy publishing workflows and PostScript/PDF production systems.
