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.
This QML type supports the following default properties. A default property may be declared inside another declared object without being assigned explicitly to a property.

Property Documentation
loadError : Error |
Returns the load error (read-only).
Note: load errors are also reported on the error property and emit the errorChanged signal.
See also Loadable.
The Enums.LoadStatus of the Raster.
See also Loadable and Enums.LoadStatus.
The path to the local raster image file.
Note: You cannot set the path to the raster after the instance is already loaded.
[default] rasterFunction : RasterFunction |
The raster function used to construct this Raster.
Returns the Raster type (read-only).
This property was introduced in Esri.ArcGISRuntime 100.1.
See also Enums.RasterType.
