Convert PHM to PCL

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 PCL file extension, Printer Command Language, is a page description language developed by Hewlett-Packard (HP) in the 1980s. It is used to control printer features and describe the layout of text and graphics on a printed page. PCL files contain commands that instruct the printer on how to print the document, including details like size, layout, and resolution. Initially designed for HP's inkjet and dot matrix printers, PCL has evolved to support various printer types, including laser printers. Its simplicity and efficiency have made it a widely adopted standard in the printing industry.
