Convert PBM to PS

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.

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.
