Troubleshooting PCX to PPM Conversion

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