Convert PFB GRAPHICS to PBM

The PFB (Printer Font Binary) file extension refers to an Adobe Type 1 font used primarily on Windows PCs. Developed by Adobe Systems, PFB files contain fonts in binary format, requiring an associated PFM (Printer Font Metrics) file for proper functionality. Initially proprietary, Adobe later released the specification to third-party font manufacturers. PFB files can also be converted to image files, and AutoCAD utilizes them to create compiled font files.

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.
