computeMinMax()

void QgsRasterLayerUtils::computeMinMax ( QgsRasterDataProvider * provider, int band, const QgsRasterMinMaxOrigin & mmo, Qgis::RasterRangeLimit limits, const QgsRectangle & extent, int sampleSize, double & min, double & max )

static

Compute the min max values for provider along band according to MinMaxOrigin parameters mmo and extent.

renderedBandForElevationAndTemporalRange()

int QgsRasterLayerUtils::renderedBandForElevationAndTemporalRange ( QgsRasterLayer * layer, const QgsDateTimeRange & temporalRange, const QgsDoubleRange & elevationRange, bool & matched )

static

Given a raster layer, returns the band which should be used for rendering the layer for a specified temporal and elevation range, respecting any elevation and temporal settings which affect the rendered band.

Parameters

layer	Target raster layer
temporalRange	temporal range for rendering
elevationRange	elevation range for rendering
matched	will be set to true if a band matching the temporal and elevation range was found

Returns

Matched band, or -1 if the layer does not have any elevation or temporal settings which affect the rendered band.
