Member Data Documentation

◆ bandNumber

int QgsRasterBandStats::bandNumber

The gdal band number (starts at 1)

Definition at line 77 of file qgsrasterbandstats.h.

◆ elementCount

qgssize QgsRasterBandStats::elementCount

The number of not no data cells in the band.

Definition at line 81 of file qgsrasterbandstats.h.

◆ extent

QgsRectangle QgsRasterBandStats::extent

Extent used to calc statistics.

Definition at line 118 of file qgsrasterbandstats.h.

◆ height

int QgsRasterBandStats::height

Number of rows used to calc statistics.

Definition at line 115 of file qgsrasterbandstats.h.

◆ maximumValue

double QgsRasterBandStats::maximumValue

The maximum cell value in the raster band.

NO_DATA values are ignored. This does not use the gdal GetMaximmum function.

Definition at line 86 of file qgsrasterbandstats.h.

◆ mean

double QgsRasterBandStats::mean

The mean cell value for the band. NO_DATA values are excluded.

Definition at line 94 of file qgsrasterbandstats.h.

◆ minimumValue

double QgsRasterBandStats::minimumValue

The minimum cell value in the raster band.

NO_DATA values are ignored. This does not use the gdal GetMinimum function.

Definition at line 91 of file qgsrasterbandstats.h.

◆ range

double QgsRasterBandStats::range

The range is the distance between min & max.

Definition at line 97 of file qgsrasterbandstats.h.

◆ statsGathered

int QgsRasterBandStats::statsGathered

Collected statistics.

Definition at line 103 of file qgsrasterbandstats.h.

◆ stdDev

double QgsRasterBandStats::stdDev

The standard deviation of the cell values.

Definition at line 100 of file qgsrasterbandstats.h.

◆ sum

double QgsRasterBandStats::sum

The sum of all cells in the band. NO_DATA values are excluded.

Definition at line 106 of file qgsrasterbandstats.h.

◆ sumOfSquares

double QgsRasterBandStats::sumOfSquares

The sum of the squares. Used to calculate standard deviation.

Definition at line 109 of file qgsrasterbandstats.h.

◆ width

int QgsRasterBandStats::width

Number of columns used to calc statistics.

Definition at line 112 of file qgsrasterbandstats.h.
