What is XBM?

X BitMap (XBM) is a monochrome image format that stores pixel data as C source code, commonly used for X11 cursor and icon bitmaps.

What is PEF?

Pentax Electronic Format (PEF) contains raw sensor data from Pentax digital SLR and mirrorless cameras.

When Should You Use XBM vs PEF?

Use XBM When...

Reach for XBM when your priority is x11 icons, monochrome graphics, embedded ui — its uncompromising quality ensures every detail is preserved.

Use PEF When...

Reach for PEF when your priority is pentax camera post-processing — its uncompromising quality ensures every detail is preserved.

XBM vs PEF: Key Differences

  • •XBM and PEF diverge on compression: lossless compression for the source, lossless compression for the target.
  • •Both formats share lossless compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
  • •How transparency is handled: PEF supports transparency, so alpha information is preserved during conversion.
  • •XBM files are typically Very small, minimal overhead while PEF files range 15-45MB per photo
  • •XBM is optimized for x11 icons, monochrome graphics, embedded ui while PEF is designed for pentax camera post-processing — choose based on your specific workflow needs

Advantages of XBM

  • ✓At its core, XBM relies on lossless encoding — a design choice that makes it perfect for X11 icons, monochrome graphics, embedded UI.
  • ✓You won't run into compatibility issues with XBM — it's a universal standard across platforms.
  • ✓File size management with XBM: larger files guaranteed to match the original exactly.
  • ✓Every major application in the X11 icons, monochrome graphics, embedded UI space supports XBM natively.

Advantages of PEF

  • ✓PEF compresses data using lossless methods, keeping file sizes manageable for Pentax camera post-processing.
  • ✓Industry-wide support means PEF files open anywhere — from legacy systems to the latest devices.
  • ✓Lossless quality makes PEF the gold standard for archival and master copies.
  • ✓From professional software to open-source alternatives, PEF works out of the box.

Troubleshooting XBM to PEF Conversion

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