About the SIXEL format
SIXEL — DEC SIXEL Graphics
SIXEL is a graphics format developed by DEC (Digital Equipment Corporation) for use in terminals and printers. It encodes bitmap images as a series of six-pixel-high bands transmitted as printable ASCII characters, and has seen a resurgence in modern terminal emulators.
Common uses
- Modern terminal emulator image display
- DEC terminal and VT-series printer output
- SSH session image viewing
- Converting images for terminal display
About the HDR format
HDR — Radiance RGBE High Dynamic Range
HDR (Radiance .hdr) is a high dynamic range image format developed for the Radiance rendering system. It stores luminance information far beyond standard 8-bit images using a shared-exponent encoding, making it the standard for HDR environment maps in 3D rendering.
Common uses
- 3D rendering environment maps (IBL)
- HDR panorama photography storage
- VFX and CGI lighting reference images
- Tone mapping source images
