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 PCX?

PCX (PC Paintbrush) is a legacy raster image format from the early days of DOS, originally created for ZSoft's PC Paintbrush.

When Should You Use XPM vs PCX?

XPM vs PCX: Key Differences

• •XPM uses lossless compression while PCX uses lossless compression — both take the same approach to file size management.
• •Since both XPM and PCX use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
• •Transparency: N/A - PCX does not support transparency
• •Storage footprint: Small, efficient for icons for XPM vs Moderate, similar to uncompressed formats for PCX.
• •XPM is optimized for x11 desktop icons, legacy unix graphics while PCX is designed for legacy graphics, retro computing — choose based on your specific workflow needs

Advantages of XPM

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

Advantages of PCX

• ✓The lossless nature of PCX means file sizes stay reasonable while handling Legacy graphics, retro computing efficiently.
• ✓From mobile devices to enterprise servers, PCX is recognized and supported everywhere.
• ✓The trade-off for PCX's perfection is larger files — but for archival work, it is worth every megabyte.
• ✓PCX is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Troubleshooting XPM to PCX Conversion

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