Crate zenlayout 

Image layout computation with constraint modes, orientation, and decoder negotiation.

Pure geometry — no pixel operations, minimal allocations, no_std compatible.

Modules

• constraint — Constraint modes (Fit, Within, FitCrop, etc.) and layout computation
• orientation — EXIF orientation, D4 dihedral group, coordinate transforms
• plan — Command pipeline, decoder negotiation, two-phase layout planning
• [svg] — SVG visualization of layout pipeline steps (requires svg feature)
• [riapi] — RIAPI query string parsing (?w=800&h=600&mode=crop) (requires riapi feature)
