PEF sekilas
PEF
Pentax raw workflows never dominated the mass market, but their persistence in enthusiast and specialist photo libraries gives PEF ongoing practical relevance.
PGM Raw sekilas
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.

FAQ
Why convert PEF 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 PEF to PGM Raw?
This conversion changes how the format behaves in downstream tools and delivery environments.
Moving to PGM Raw removes camera raw data.
What should I review after converting PEF to PGM Raw?
Validate output quality on representative files and confirm the target format behaves correctly in the destination workflow.
