About the SIX 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 PGM format
PGM — Portable Graymap
PGM is the grayscale member of the Netpbm family. It stores each pixel as a gray value (8 or 16 bits), making it ideal for grayscale image processing, scientific imaging, and intermediate conversion steps. Like PBM, it can be stored as ASCII or binary.
Common uses
- Grayscale image processing and analysis
- Scientific and medical image workflows
- Machine learning image preprocessing
- Intermediate format in Netpbm conversions
