Convert PFB GRAPHICS to CAL

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 CAL file extension, known as CALS (Continuous Acquisition and Life-cycle Support) Type 1 Image, is a 1-bit black-and-white raster image format developed by the U.S. Department of Defense in the mid-1980s to standardize graphics data interchange for military documentation. It is primarily used for storing and sharing monochrome images while retaining orientation metadata. The format supports both uncompressed and compressed (using CCITT Group 4 compression) images.
