    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.

    See also Loadable and Object.

    [signal] void Raster::loadStatusChanged(Esri::ArcGISRuntime::LoadStatus loadStatus)

    Signal emitted when the loadStatus changes for this object.
