Convert PJPEG to PS

The PJPEG (Progressive JPEG) is a file extension for images that enhances the standard JPEG format by displaying images in successive waves of increasing detail, improving the user experience during slow network conditions. The JPEG stands for "Joint Photographic Experts Group", the organization that developed the standard in 1992. PJPEG is particularly useful for web applications, as it allows images to appear more quickly and progressively refine in quality, rather than loading from top to bottom like baseline JPEGs.

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.
