About the RAS format
RAS — Sun Rasterfile
RAS is the Sun Microsystems rasterfile format (also called SUN format), the native image format for SunOS and Solaris workstations. It was used for screenshots, icons, and application graphics on Sun hardware and is still encountered in legacy Unix archives.
Common uses
- Legacy Solaris/SunOS graphics files
- Converting old Sun workstation screenshots
- Unix workstation archive recovery
- Historical software documentation images
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
