Understanding RAW and PGM Formats

Learn about the source and target file formats to understand what happens during conversion.

Source Format

Raw Image Data

application/octet-stream

RAW is a general term for unprocessed image data files captured directly from a camera's image sensor, though the .raw extension itself is sometimes used as a generic raw container. Different camera manufacturers use various proprietary raw formats, but files labeled .raw contain minimally processed sensor data preserving maximum detail and dynamic range. These files require specialized software to develop into viewable images.

Advantages

  • Contains the maximum possible image data from the camera sensor
  • Provides full control over white balance, exposure, and color in post-processing
  • Much higher dynamic range than processed JPEG output

Limitations

  • Generic .raw extension can cause compatibility issues with software detection
  • Very large file sizes compared to processed image formats
  • Cannot be displayed directly without raw processing software

Common Uses

  • Generic raw image capture from various camera systems
  • Raw image data from scientific and industrial imaging sensors
  • Intermediate data storage in image processing workflows

Target Format

PGM Image

image/x-portable-graymap

PGM (Portable Graymap Format) is a grayscale image format in the Netpbm family, storing single-channel pixel intensity values. Like other Netpbm formats, it supports both ASCII (human-readable) and binary (compact) encoding modes. PGM is commonly used in academic and scientific contexts where simplicity and ease of programmatic manipulation are priorities.

Advantages

  • Very simple specification that is trivial to parse and generate
  • Lossless storage of grayscale image data
  • No external library dependencies required for reading or writing

Limitations

  • No compression results in large file sizes
  • Limited to single-channel grayscale images only
  • Not supported by web browsers or most consumer software

Common Uses

  • Computer vision research and academic image processing
  • Grayscale image data interchange in scientific computing
  • Input and output format for command-line image manipulation tools
