Convert ICON to PFM

An ICON file, an abbreviation for Icon Image File, is primarily used in Microsoft Windows operating systems to represent graphical icons. These files are essential for visually identifying applications, files, and folders, enhancing user experience through graphical representation. ICON files support multiple sizes and color depths, ensuring compatibility and visual clarity across different display settings. Introduced in the early versions of Windows, ICON files have evolved to accommodate higher resolutions and color variations, aligning with advancements in display technology. Their primary function is to provide a quick, intuitive visual reference for software and system elements.

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.
