Member Data Documentation

int QgsRasterBandStats::bandNumber

The gdal band number (starts at 1)

Definition at line 75 of file qgsrasterbandstats.h.

qgssize QgsRasterBandStats::elementCount

The number of not no data cells in the band.

Definition at line 79 of file qgsrasterbandstats.h.

QgsRectangle QgsRasterBandStats::extent

Extent used to calc statistics.

Definition at line 114 of file qgsrasterbandstats.h.

int QgsRasterBandStats::height

Number of rows used to calc statistics.

Definition at line 111 of file qgsrasterbandstats.h.

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 83 of file qgsrasterbandstats.h.

double QgsRasterBandStats::mean

The mean cell value for the band.

NO_DATA values are excluded.

Definition at line 90 of file qgsrasterbandstats.h.

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 87 of file qgsrasterbandstats.h.

double QgsRasterBandStats::range

The range is the distance between min & max.

Definition at line 93 of file qgsrasterbandstats.h.

int QgsRasterBandStats::statsGathered

Collected statistics.

Definition at line 99 of file qgsrasterbandstats.h.

double QgsRasterBandStats::stdDev

The standard deviation of the cell values.

Definition at line 96 of file qgsrasterbandstats.h.

double QgsRasterBandStats::sum

The sum of all cells in the band.

NO_DATA values are excluded.

Definition at line 102 of file qgsrasterbandstats.h.

double QgsRasterBandStats::sumOfSquares

The sum of the squares.

Used to calculate standard deviation.

Definition at line 105 of file qgsrasterbandstats.h.

int QgsRasterBandStats::width

Number of columns used to calc statistics.

Definition at line 108 of file qgsrasterbandstats.h.
