Convert CAL to PS

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.

The PostScript (PS) file extension stands for "PostScript", a dynamic page description language developed by Adobe in the early 1980s. Primarily used for desktop publishing, vector graphics, and printing tasks, PS files are particularly beneficial in ensuring high-quality output across various devices. As a precursor to PDFs, they encode textual and graphical content with great precision, facilitating consistent rendering on any platform. Renowned for their robust and flexible nature, PostScript files have played a pivotal role in digital typography and printing, underpinning many modern typesetting applications and output systems.
