What is CGM?

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

What is X3F?

Sigma Raw (X3F) contains raw sensor data from Sigma cameras using the unique Foveon X3 sensor technology.

When Should You Use CGM vs X3F?

Use CGM When...

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

Use X3F When...

Reach for X3F when your priority is sigma/foveon camera raw processing — its uncompromising quality ensures every detail is preserved.

CGM vs X3F: Key Differences

  • •The core technical difference: CGM relies on lossless compression whereas X3F 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: X3F lacks transparency support.
  • •Storage footprint: Compact for vector drawings for CGM vs 25-60MB per photo for X3F.
  • •Primary audience: CGM is built for technical illustrations, engineering diagrams scenarios, while X3F focuses on sigma/foveon camera raw processing — pick the format that matches your output requirement.

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 X3F

  • ✓X3F compresses data using lossless methods, keeping file sizes manageable for Sigma/Foveon camera raw processing.
  • ✓Industry-wide support means X3F files open anywhere — from legacy systems to the latest devices.
  • ✓Lossless quality makes X3F the gold standard for archival and master copies.
  • ✓From professional software to open-source alternatives, X3F works out of the box.

Common Use Cases for CGM to X3F Conversion

Troubleshooting CGM to X3F Conversion

  • !X3F shows visible compression artifacts → lower the compression level or switch to a lossless variant
  • !The converted X3F image looks washed out → the source CGM likely uses a wider color space than X3F supports
  • !X3F file is much larger than expected → check if the conversion preserved an unnecessarily high resolution
  • !Text in the converted X3F looks fuzzy → text-heavy images benefit from higher quality settings or a different output format
