DDS in sintesi
DDS
DDS grew out of Microsoft's graphics API and game-development ecosystem, which is why it feels more like an engine or texture-delivery format than a conventional consumer image file.
PGM Raw in sintesi
PGM Raw
The raw PGM branch reflects the practical evolution of Netpbm-style tool formats: keep the tiny header and easy parsing, but move the pixel raster into a binary form that is much more usable for real data sizes.

Quando usare ciascun formato
When to use DDS
- Your source file is already in DDS.
- Preserve source expectations before exporting to PGM Raw.
- DDS is commonly used in image workflows.
When to use PGM Raw
- Your target workflow expects PGM Raw.
- Improve delivery compatibility with PGM Raw.
- PGM Raw is commonly used in image workflows.
Domande frequenti
Why convert DDS to PGM Raw?
Convert to PGM raw when a pipeline needs direct grayscale raster data for vision research, microscopy or scientific-image preprocessing, algorithm tests, or command-line tooling where minimal format overhead matters.
It is particularly useful as an intermediate format between automated processing steps.
What changes when converting DDS to PGM Raw?
This conversion changes how the format behaves in downstream tools and delivery environments.
What should I review after converting DDS to PGM Raw?
Validate output quality on representative files and confirm the target format behaves correctly in the destination workflow.
