Detailed Description

This symbol layer, in a MultilayerPointSymbol, places a picture marker at the location of the point feature. The class supports changing dimensions of the marker, specifying the image (or url linking to the image) to use as the marker, as well as the general marker options provided by the MarkerSymbolLayer base class.

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.

Example:

Create a PictureMarkerSymbolLayer and set its URL to an online PNG:

PictureMarkerSymbolLayer {
    id: pictureMarkerSymbolLayer
    url: "http://static.arcgis.com/images/Symbols/Basic/YellowStickpin.png"
}

Property Documentation

[default] credential : Credential

The credential to be used to access a secured image URL if provided.

A credential can only be provided before the picture marker symbol layer is loaded.


error : Error

Returns the error object (read-only).

See also Loadable and Error.


image : url

Returns the picture marker symbol layer image once loaded (read-only).

If a URL was provided for the picture marker symbol layer, an attempt to load the symbol must occur and succeed, and then the image provider source is available via this property. Prior to loading in this case, this will return an empty url.


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.


loadStatus : Enums.LoadStatus

Returns the load status (read-only).

See also Loadable and Enums.LoadStatus.


[default] requestConfiguration : RequestConfiguration

The configuration parameters used for network requests sent by this symbol.


tintColor : color

The tint color of the picture marker symbol layer.

The tint color is applied to the entire image by multiplying each RGB color channel in the image by the corresponding color channel of the tint color. The default color is white with 100% opacity (RGBA (255,255,255,255)), which when applied leaves the image with its native colors and unchanged opacity. A white tint color with opacity less than 100% applies the reduced opacity without changing the image colors.

This QML property was introduced in Esri.ArcGISRuntime 100.6.


url : url

The URL path to the picture marker symbol layer image.

This could be a local file path, Qt resource path, or HTTP path to the image. The URL can only be provided before the picture marker symbol layer is loaded.
