Troubleshooting MEF to PAM Conversion

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