TEX at a glance
TEX
Donald Knuth created TeX in response to dissatisfaction with the quality of mathematical typesetting, and its ecosystem later expanded through LaTeX and related tooling.
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.

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