A class representing a picture fill symbol layer.
The class represents a polygon geometry filled with an image. This symbol layer, if it is the sole symbol layer in an AGSMultilayerPolygonSymbol
fills the geometry associated with the symbol with the specified image. The image, should it not fill the geometry, will be tiled throughout the fill.
It is also used to represent the Web Scene specification's Icon3DSymbolLayers. IconSymbol3DLayers from Web Scene JSON as long as those Icon3DSymbolLayers contain pictures rather than primitives or vector paths, those symbol layers are represented as instances of AGSPictureFillSymbolLayer
. If those Icon3DSymbolLayers are primitives or vector paths, they are represented as AGSVectorMarkerSymbolLayer
objects.
It provides a similar user experience to the simple AGSPictureFillSymbol
, but can be used in an AGSMultilayerSymbol
.

Loads data for the object asynchronously. The completion block is invoked upon completion.
You can call this method any number of times, however only one attempt is made to load the data. If it is already loading, it will just continue to load (i.e. not force a reload). If it has already loaded successfully, the completion block will be invoked right away. If it has already failed to load, the completion block will be invoked right away with error previously encountered. This method supports multiple callers and will call them all back on completion. However, each caller's completion block will be invoked once and only once.
- Parameters
-
completion | block that is invoked when object loads successfully or fails to load. An error is passed to the block if the object fails to load. |
- Note
- The completion block is always invoked on the main thread.

Tries to reload when an object has failed to load. This method should be called judiciously. It should be called when:
- you didn't have network connectivity earlier when it failed and you want to retry now that you have connectivity
- the server was down earlier when it failed and you want to retry
- the request is taking too long and you want to cancel it and retry, in which case you will first call
cancelLoad
and then this method
If the data hasn't started loading, it will start loading. If it is already loading, it will just continue to load. If it has already loaded successfully, calls back right away. If it has already failed to load, tries again. This method supports multiple callers and will call them all back on completion. However, each caller's completion block will be invoked once and only once.
- Parameters
-
completion | block that is invoked when object loads successfully or fails to load. An error is passed to the block if the object fails to load. |
- Note
- The completion block is always invoked on the main thread.

The tint color of a picture fill 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 tint color is white with 100% opacity, i.e. RGBA(255, 255, 255, 255), which leaves the image with its native colors. A white tint color with opacity less than 100% tints the image white, with the reduced opacity respected.
When getting the tint color from a symbol, the consensus value is reported. If there is no consensus (one or more layers have different colors), a nil
value is reported for the color. Likewise, setting a value for tint color on a symbol will apply that tint color to all layers the symbol contains.
