What is XPM?

X PixMap (XPM) is a color image format for X11 GUI icons, storing pixel data as C source code with color-key transparency.

What is X3F?

Sigma Raw (X3F) contains raw sensor data from Sigma cameras using the unique Foveon X3 sensor technology.

When Should You Use XPM vs X3F?

Use XPM When...

Reach for XPM when your priority is x11 desktop icons, legacy unix graphics — its uncompromising quality ensures every detail is preserved.

Use X3F When...

Reach for X3F when your priority is sigma/foveon camera raw processing — its uncompromising quality ensures every detail is preserved.

XPM vs X3F: Key Differences

  • •The core technical difference: XPM relies on lossless compression whereas X3F uses lossless compression.
  • •Neither format changes compression philosophy — both are lossless compression — so any size differences are due to encoding efficiency, not a shift in quality approach.
  • •Transparency: N/A
  • •Storage footprint: Small, efficient for icons for XPM vs 25-60MB per photo for X3F.
  • •Primary audience: XPM is built for x11 desktop icons, legacy unix graphics scenarios, while X3F focuses on sigma/foveon camera raw processing — pick the format that matches your output requirement.

Advantages of XPM

  • ✓XPM applies lossless compression specifically calibrated for X11 desktop icons, legacy Unix graphics.
  • ✓XPM enjoys broad native support across operating systems, browsers, and creative tools alike.
  • ✓XPM guarantees every bit of the original data survives — no approximations, no shortcuts.
  • ✓You will find XPM support built into virtually every tool that handles X11 desktop icons, legacy Unix graphics — no plugins or converters needed.

Advantages of X3F

  • ✓X3F applies lossless compression specifically calibrated for Sigma/Foveon camera raw processing.
  • ✓X3F enjoys broad native support across operating systems, browsers, and creative tools alike.

Troubleshooting XPM to X3F Conversion

  • !X3F shows visible compression artifacts → lower the compression level or switch to a lossless variant
  • !The converted X3F image looks washed out → the source XPM likely uses a wider color space than X3F supports
  • !X3F file is much larger than expected → check if the conversion preserved an unnecessarily high resolution
  • !Text in the converted X3F looks fuzzy → text-heavy images benefit from higher quality settings or a different output format
