sec_interp.gui.adapters.geometry_stats.profile_raster_statistics(line_geom: qgis.core.QgsGeometry, raster_layer: qgis.core.QgsRasterLayer, band_number: int, distance_area: qgis.core.QgsDistanceArea) → ProfileRasterStats | None

Compute min/max/mean elevation over unique DEM cells along the line.

Densifies at the CRS-aware raster resolution, reprojects each sample into the raster CRS and collapses samples that fall in the same pixel cell (so repeated cells from the densification do not bias min/max/mean). Returns None when there is nothing usable to sample.
