Detailed Description
An ImageFrame can contain images that do not have georeferencing information. In such cases, location data can be provided to geolocate the image.
See also ImageOverlay.
Member Function Documentation
[explicit] ImageFrame::ImageFrame (const QUrl &url, QObject *parent = nullptr)
Creates an ImageFrame containing the image defined by the provided URL.
- url - A URL that identifies a local or online image source.
- parent - The optional parent QObject.
Supported image formats are GeoTIFF, TIFF, JPEG, and PNG. The URL can be a local file path or an HTTP path to an image.
ImageFrame::ImageFrame (const QUrl &url, Esri::ArcGISRuntime::Credential *credential, QObject *parent = nullptr)
Creates an image frame containing the image defined by the url, a credential, and an optional parent.
This url could be a local file path, Qt resource path, or HTTP path to the image.
A credential is specified if the image needs authentication to gain access to it.
Supported image formats are GEOTIFF, TIFF, JPEG, and PNG.
ImageFrame::ImageFrame (const QUrl &url, const Esri::ArcGISRuntime::Envelope &extent, QObject *parent = nullptr)
Creates an ImageFrame containing the image identified by the URL for display at the specified geographic extent.
- url - A URL that identifies a local or online image source.
- extent - The geographic extent at which the image is displayed.
- parent - The optional parent QObject.
If a spatial reference is not defined for the extent, it is assumed to be the same as the scene. If the spatial reference of the extent is different from that of the scene, then the image would fail to render. Supported image formats are GeoTIFF, TIFF, JPEG, and PNG. The URL can be a local file path or an HTTP path to an image.
ImageFrame::ImageFrame (const QUrl &url, const Esri::ArcGISRuntime::Envelope &extent, Esri::ArcGISRuntime::Credential *credential, QObject *parent = nullptr)
Creates an ImageFrame containing the image identified by the url secured by a credential, for display at the specified geographic extent and an optional parent.
This url could be a local file path, Qt resource path, or HTTP path to the image.
If a spatial reference is not defined for the extent, it is assumed to be the same as the scene. Otherwise, the extent will be projected to match the scene.
A credential is specified if the image needs authentication to gain access to it.
Supported image formats are GEOTIFF, TIFF, JPEG, and PNG.
ImageFrame::ImageFrame (const QUrl &url, const Esri::ArcGISRuntime::Polygon &quadrilateral, QObject *parent = nullptr)
Creates an ImageFrame using the URL of an image and a four-point polygon representing the corners of an image.
- url - A URL that identifies a local or online image source.
- quadrilateral - A polygon consisting of four points that represent each corner of the image.
- parent - The optional parent QObject.
If a spatial reference is not defined for the polygon, it is assumed to be the same as the scene. If the spatial reference of the extent is different from that of the scene, then the image would fail to render. If the provided polygon doesn't contain exactly four points, the image frame will fail to load. Supported image formats are GeoTIFF, TIFF, JPEG, and PNG. The URL can be a local file path or an HTTP path to an image.
ImageFrame::ImageFrame (const QUrl &url, const Esri::ArcGISRuntime::Polygon &quadrilateral, Esri::ArcGISRuntime::Credential *credential, QObject *parent = nullptr)
Creates an ImageFrame containing the image identified by the url secured by a credential for display, quadrilateral, and an optional parent.
This url could be a local file path, Qt resource path, or HTTP path to the image.
The quadrilateral in this case is a four-point polygon and the image frame will fail to load if the number of points is more or less. If a spatial reference is not defined for the polygon, it is assumed to be the same as the scene. Otherwise, the extent will be projected to match the scene.
A credential is specified if the image needs authentication to gain access to it.
Supported image formats are GEOTIFF, TIFF, JPEG, and PNG.
ImageFrame::ImageFrame (const QImage &image, const Esri::ArcGISRuntime::Envelope &extent, QObject *parent = nullptr)
Creates an ImageFrame containing the image for display at the specified geographic extent.
- image - An image to display in the frame.
- extent - The geographic extent at which the image is displayed.
- parent - The optional parent QObject.
If a spatial reference is not defined for the extent, it is assumed to be the same as the scene. If the spatial reference of the extent is different from that of the scene, then the image would fail to render. Supported image formats are TIFF, GeoTIFF, ICO, BMP, GIF, JPEG, and PNG. Animated GIF is not supported.
ImageFrame::ImageFrame (const QImage &image, const Esri::ArcGISRuntime::Polygon &quadrilateral, QObject *parent = nullptr)
Creates an ImageFrame using the image and a four-point polygon representing the corners of an image.
- image - An image to display in the frame.
- quadrilateral - A polygon consisting of four points that represent each corner of the image.
- parent - The optional parent QObject.
If a spatial reference is not defined for the polygon, it is assumed to be the same as the scene. If the spatial reference of the extent is different from that of the scene, then the image would fail to render. If the provided polygon doesn't contain exactly four points, the image frame will fail to load. Supported image formats are TIFF, GeoTIFF, ICO, BMP, GIF, JPEG, and PNG. Animated GIF is not supported.
[override virtual] ImageFrame::~ImageFrame ()

Reimplements: RemoteResource::credential() const.
Returns the security credentials to access the remote resource. Only applicable if the resource is secured.
[signal] void ImageFrame::doneLoading (const 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.
