Convert PICON to PHM

The PICON file extension, short for Personal Icon, is primarily used for small personal icons. These icons are commonly employed in digital satellite receivers to identify various channels and on websites to add small icons to the web address bar. The PICON format, classified as a raster image file, supports multiple operating systems, including Windows, macOS, and Linux. Its history traces back to its use in Dreambox satellite receivers, where it enhanced user interface customization.

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.
