About the HRZ format
HRZ — Slow Scan Television Image
HRZ is a raw image format associated with Slow Scan Television (SSTV), a method of transmitting images over radio (shortwave or amateur radio). SSTV images are 256×240 pixels encoded as audio tones and used by amateur radio operators worldwide.
Common uses
- Amateur radio SSTV image transmission and reception
- Converting SSTV received images to standard formats
- Ham radio image archiving
- Historical radio communication image recovery
About the PFM format
PFM — Portable Float Map
PFM is an extension of the Netpbm format that stores floating-point pixel values instead of integers. This makes it ideal for high dynamic range (HDR) image storage, scientific imaging, and rendering output where pixel values can exceed the 0–1 range.
Common uses
- HDR image storage and processing
- Computer graphics rendering output
- Scientific image data with floating-point values
- Tone mapping pipeline input/output
