PFM Raw at a glance
PFM Raw
Convert to PFM raw when HDR rendering, tone-mapping, or scientific-imaging workflows need floating-point pixel values to survive intact between tools.
It is especially useful as an intermediate format for graphics research, physically based rendering, and analytical image-processing pipelines that operate on scene-referred data.
Xfig at a glance
Xfig
Technical diagrams and figures in Unix academic workflows, legacy Xfig drawing migration, and scientific publication figure production on Unix.
