Convert PICON to PFM

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 Portable Floatmap (PFM) file format, also known as Portable FloatMap, is an image file format designed to store High Dynamic Range (HDR) images using floating-point values. Developed in the spirit of the Portable Pixmap format, PFM files contain image data with resolutions and byte order specified in the header. This format is particularly useful for applications requiring precise image data, such as computer graphics and image processing. PFM has been widely adopted in the IT industry for its ability to handle a wide range of pixel values beyond the standard 0-255 range, making it ideal for HDR imaging and other advanced visualizations.
