Detailed Description
A raster consists of a matrix of cells (or pixels) organized into rows and columns (or a grid) where each cell contains a value representing information, such as temperature. Rasters are digital aerial photographs, imagery from satellites, digital pictures, or even scanned maps.
It can be created from a raster file on device or from a raster function.
Supported Raster formats include:
- ASRP/USRP
- CIB1, 5, 10
- DTED0, 1, 2
- GeoTIFF
- HFA
- HRE
- IMG
- JPEG
- JPEG 2000
- NITF
- PNG
- RPF
- SRTM1, 2
- Mosaic Dataset in SQLite (read-only)
Learn more about rasters from the ArcGIS Desktop documentation.

Member Function Documentation
Raster::Raster(Esri::ArcGISRuntime::RasterFunction *rasterFunction , QObject *parent = nullptr)
Constructor that takes a rasterFunction and an optional parent.
Raster::Raster(const QString &path, QObject *parent = nullptr)
Constructor that takes a path to a local raster file and an optional parent.
[signal] void Raster::doneLoading (Esri::ArcGISRuntime::Error loadError )
Signal emitted when this object is done loading.
- loadError - Details about any error that may have occurred.
Note: If there is a load error it will also be emitted on the errorOccurred signal.
[signal] void Raster::loadStatusChanged (Esri::ArcGISRuntime::LoadStatus loadStatus )
Signal emitted when the loadStatus changes for this object.
