Troubleshooting GBR to XBM Conversion

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