Convert PFA GRAPHICS to PPM

The PFA (Printer Font ASCII) file extension, developed by Adobe Systems, stores Adobe Type 1 fonts in a human-readable ASCII format, which can be converted to image files. Introduced as part of the PostScript character category in 1982, PFA files contain glyph data and can be opened in any text editor. They are primarily used on Linux and UNIX-like platforms and are incorporated into systems by copying them into the Fonts folder. The binary counterpart of PFA is the PFB (Printer Font Binary) file.

The Portable Pixmap (PPM) file extension, an image format within the Netpbm family, stores simple, uncompressed images. Introduced in the late 1980s, PPM supports RGB color and grayscale images, making it suitable for basic image processing and conversion tasks. Its plain text encoding simplifies debugging and data manipulation, although its lack of compression results in larger file sizes compared to modern formats. As such, PPM finds limited use in contemporary applications, mainly in educational and experimental settings where ease of implementation and readability are prioritized.
