PFM in sintesi
PFM
These formats persist in engineering, compression research, and conversion-tool contexts where simple sample storage or adjunct technical representation is useful.
PAM in sintesi
PAM
PBM, PGM, PPM, PNM, and later PAM come from the tool-centric tradition of keeping image interchange formats easy to parse, script, and transform.

Quando usare ciascun formato
When to use PFM
- Your source file is already in PFM.
- Preserve source expectations before exporting to PAM.
- PFM is commonly used in image workflows.
When to use PAM
- Your target workflow expects PAM.
- Improve delivery compatibility with PAM.
- PAM is commonly used in image workflows.
Domande frequenti
Why convert PFM to PAM?
Convert to PAM when using Unix-style image tools or scripted workflows that benefit from a simple, explicit raster container with more flexibility than PBM/PGM/PPM.
It is useful as an intermediate technical format.
What changes when converting PFM to PAM?
This conversion changes how the format behaves in downstream tools and delivery environments.
Moving to PAM removes HDR content.
What should I review after converting PFM to PAM?
Validate output quality on representative files and confirm the target format behaves correctly in the destination workflow.
