What is CGM?

Computer Graphics Metafile (CGM) is a vector and raster graphics format for technical illustrations and engineering diagrams.

What is DCR?

Kodak Digital Camera Raw (DCR) is a raw image format from Kodak digital cameras, preserving sensor data for post-processing.

When Should You Use CGM vs DCR?

Use CGM When...

Reach for CGM when your priority is technical illustrations, engineering diagrams — its uncompromising quality ensures every detail is preserved.

Use DCR When...

Reach for DCR when your priority is kodak camera post-processing, legacy photo editing — its uncompromising quality ensures every detail is preserved.

CGM vs DCR: Key Differences

  • •The core technical difference: CGM relies on lossless compression whereas DCR uses lossless compression.
  • •Neither format changes compression philosophy — both are lossless compression — so any size differences are due to encoding efficiency, not a shift in quality approach.
  • •Alpha channel support: DCR lacks transparency support.
  • •CGM files are typically Compact for vector drawings while DCR files range 10-25MB per image from Kodak cameras
  • •CGM is optimized for technical illustrations, engineering diagrams while DCR is designed for kodak camera post-processing, legacy photo editing — choose based on your specific workflow needs

Advantages of CGM

  • ✓The lossless nature of CGM means file sizes stay reasonable while handling Technical illustrations, engineering diagrams efficiently.
  • ✓From mobile devices to enterprise servers, CGM is recognized and supported everywhere.
  • ✓The trade-off for CGM's perfection is larger files — but for archival work, it is worth every megabyte.
  • ✓CGM is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Advantages of DCR

  • ✓DCR applies lossless compression specifically calibrated for Kodak camera post-processing, legacy photo editing.
  • ✓DCR enjoys broad native support across operating systems, browsers, and creative tools alike.
  • ✓DCR guarantees every bit of the original data survives — no approximations, no shortcuts.
  • ✓You will find DCR support built into virtually every tool that handles Kodak camera post-processing, legacy photo editing — no plugins or converters needed.

Troubleshooting CGM to DCR Conversion

  • !DCR shows visible compression artifacts → lower the compression level or switch to a lossless variant
  • !The converted DCR image looks washed out → the source CGM likely uses a wider color space than DCR supports
  • !DCR file is much larger than expected → check if the conversion preserved an unnecessarily high resolution
  • !Text in the converted DCR looks fuzzy → text-heavy images benefit from higher quality settings or a different output format
