Troubleshooting PPM to PCX Conversion

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