Convert PFM to FLIF

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.

The Free Lossless Image Format (FLIF) is a lossless image compression format designed to outperform other formats like PNG, lossless WebP, and JPEG 2000 in terms of compression ratio. Introduced in 2015, FLIF uses MANIAC (Meta-Adaptive Near-zero Integer Arithmetic Coding) for efficient compression, making it suitable for various image types without quality loss. Despite its advantages, FLIF development ceased as it was superseded by JPEG XL.
