PGM Raw at a glance

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.

ICB at a glance

ICB

The Truevision line grew out of EPICenter-era PC graphics boards, and several board names ended up surviving as filename extensions even when the underlying raster structure stayed close to the wider TGA family.

What changes when converting PGM Raw to ICB?

Convert to ICB when recovering historical raster assets from Truevision-era systems or normalizing old image archives before moving them into PNG, TIFF, or another contemporary format. It is mainly a compatibility target for legacy graphics collections.

What should I review after converting PGM Raw to ICB?

After conversion, review these destination checks: Open converted output in ImageMagick and verify behavior on real samples; Compare output against the expected depends quality profile; Weak modern software recognition compared with ordinary.tga files.

How can I keep quality stable in PGM Raw to ICB conversion?

Run representative samples, keep settings deterministic, and monitor these risks: Public documentation is mostly historical or secondary; Weak modern software recognition compared with ordinary.tga files; Validate destination compatibility before large-batch conversion.
