What is CGM?

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

What is ORF?

Olympus Raw Format (ORF) contains raw sensor data from Olympus OM-D, PEN, and other Olympus digital cameras.

When Should You Use CGM vs ORF?

Use CGM When...

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

Use ORF When...

Reach for ORF when your priority is olympus camera raw processing — its uncompromising quality ensures every detail is preserved.

CGM vs ORF: Key Differences

  • •CGM and ORF diverge on compression: lossless compression for the source, lossless compression for the target.
  • •Both formats share lossless compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
  • •Transparency: N/A
  • •Storage footprint: Compact for vector drawings for CGM vs 15-40MB per photo for ORF.
  • •Primary audience: CGM is built for technical illustrations, engineering diagrams scenarios, while ORF focuses on olympus camera raw processing — pick the format that matches your output requirement.

Advantages of CGM

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

Advantages of ORF

  • ✓At its core, ORF relies on lossless encoding — a design choice that makes it perfect for Olympus camera raw processing.
  • ✓You won't run into compatibility issues with ORF — it's a universal standard across platforms.
  • ✓File size management with ORF: larger files guaranteed to match the original exactly.
  • ✓Every major application in the Olympus camera raw processing space supports ORF natively.

Troubleshooting CGM to ORF Conversion

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