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 PAM format
PAM — Portable Arbitrary Map
PAM is an extended Netpbm format that generalizes PBM/PGM/PPM to support arbitrary numbers of channels and depths. It can store RGBA (color with transparency), CMYK, or any custom multi-channel image, making it the most capable member of the Netpbm family.
Common uses
- RGBA image storage with transparency
- Multi-channel scientific image data
- Flexible image pipeline interchange
- Extending Netpbm workflows to alpha and CMYK
