Troubleshooting DPX to PGM Conversion

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