Convert PHM to PS

The PHM file extension stands for Portable Float-map Image (16-bit half), a format used for storing High Dynamic Range (HDR) images with 16-bit half-precision floating-point values. This format is particularly useful in applications requiring precise color representation and extensive dynamic range, such as computer graphics, image processing, and scientific visualization. Originating from the Portable FloatMap (PFM) format, PHM was developed to provide a more efficient storage solution by utilizing half-precision floats, thereby reducing file size while maintaining significant detail and accuracy.

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.
