Troubleshooting ORF to XPM Conversion

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