Convert PFA GRAPHICS to PBM

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 PBM (Portable Bitmap) file extension, part of the Netpbm project, originated in the late 1980s to facilitate efficient and portable graphics file interchange. Primarily, PBM files are used to store monochrome bitmaps in a simple ASCII text format, ensuring easy compatibility across different systems and platforms. This format supports only black-and-white imagery, making it particularly useful in scenarios where simplicity and minimalism are prioritized, such as in Unix environments for bitmap manipulation and transfer. Its historical significance lies in promoting a standardized approach to bitmap graphics in early computer technology.
