Member Function Documentation

createSingleBandMemoryDataset()

gdal::dataset_unique_ptr QgsGdalUtils::createSingleBandMemoryDataset ( GDALDataType  dataType, QgsRectangle  extent, int  width, int  height, const QgsCoordinateReferenceSystem &  crs  )

static

Creates a new single band memory dataset with given parameters.

Since

QGIS 3.8

Definition at line 37 of file qgsgdalutils.cpp.

createSingleBandTiffDataset()

gdal::dataset_unique_ptr QgsGdalUtils::createSingleBandTiffDataset ( QString  filename, GDALDataType  dataType, QgsRectangle  extent, int  width, int  height, const QgsCoordinateReferenceSystem &  crs  )

static

Creates a new single band TIFF dataset with given parameters.

Since

QGIS 3.8

Definition at line 62 of file qgsgdalutils.cpp.

helpCreationOptionsFormat()

QString QgsGdalUtils::helpCreationOptionsFormat ( QString  format )

static

Gets creation options metadata for a given format.

Since

QGIS 3.10

Definition at line 123 of file qgsgdalutils.cpp.

papszFromStringList()

char ** QgsGdalUtils::papszFromStringList ( const QStringList &  list )

static

Helper function.

Since

QGIS 3.10

Definition at line 152 of file qgsgdalutils.cpp.

resampleSingleBandRaster()

void QgsGdalUtils::resampleSingleBandRaster ( GDALDatasetH  hSrcDS, GDALDatasetH  hDstDS, GDALResampleAlg  resampleAlg  )

static

Resamples a single band raster to the destination dataset with different resolution (and possibly with different CRS).

Ideally the source dataset should cover the whole area or the destination dataset.

Since

QGIS 3.8

Definition at line 93 of file qgsgdalutils.cpp.

supportsRasterCreate()

bool QgsGdalUtils::supportsRasterCreate ( GDALDriverH  driver )

static

Reads whether a driver supports GDALCreate() for raster purposes.

Parameters

driver

GDAL driver

Returns

true if a driver supports GDALCreate() for raster purposes.

Definition at line 24 of file qgsgdalutils.cpp.

validateCreationOptionsFormat()

QString QgsGdalUtils::validateCreationOptionsFormat ( const QStringList &  createOptions, QString  format  )

static

Validates creation options for a given format, regardless of layer.

Since

QGIS 3.10

Definition at line 163 of file qgsgdalutils.cpp.
