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
About the BZ2 format
BZ2 — Bzip2 Compressed File
BZ2 is a single-file compression format using the bzip2 algorithm (Burrows-Wheeler transform + Huffman coding). It consistently achieves 10-15% better compression ratios than gzip for text and source code, making it preferred for bandwidth-sensitive distributions. Like gzip, it compresses only a single file — directories must be bundled with TAR first.
Common uses
- Compressing large text files and source code archives
- Linux package distribution (.deb source packages)
- Scientific data compression
- Bandwidth-sensitive file distribution
