OTB Wrapper in link2GI
Two APIs: legacy vs. Self-describing | Legacy API (parseOTBFunction() / runOTB()) | Self-describing API (recommended) | Minimal workflow (Self-describing) | Typical transparent workflow (Self-describing) | Example: DimensionalityReduction (PCA) | Legacy workflow (supported but not recommended) | What changed (Self-describing) | Compatibility and deprecations | Compatibility | Deprecations (explicit list)
