Convert HRZ to PFM

The HRZ file extension is associated with Slow Scan Television (SSTV), a method used by amateur radio operators to transmit still images via radio waves. HRZ files store images rendered from SSTV audio signals, typically as 256x240 pixel RGB bitmaps. These files can be viewed using software like XnViewMP or Logipole Konverter. SSTV allows for the transmission of images over high-frequency bands using single-sideband modulation (SSB). The HRZ format is not widely produced by specific programs, but several image viewers support it.

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.
