Image
Image source, allows a georeferenced raster image to be shown on the map.
The georeferenced image scales and rotates as the user zooms and rotates the map. The geographic location of the raster image content, supplied with LatLngQuad, can be non-axis aligned.
Constructors
Create an ImageSource from coordinates and an image URL
Create an ImageSource from coordinates and an image URI
Create an ImageSource from coordinates and a bitmap image
Create an ImageSource from coordinates and a bitmap image resource
Functions
Retrieve the source attribution.
Retrieve current maximum overscale factor for parent tiles.
Retrieve the minimum tile update interval, which is used to throttle the tile update network requests.
Retrieve current pre-fetching zoom delta.
Retrieve whether or not the fetched tiles for the given source should be stored in the local cache
Updates the latitude and longitude of the four corners of the image
When a set of tiles for a current zoom level is being rendered and some of the ideal tiles that cover the screen are not yet loaded, parent tile could be used instead. This might introduce unwanted rendering side-effects, especially for raster tiles that are overscaled multiple times. This method sets the maximum limit for how much a parent tile can be overscaled.
Sets the minimum tile update interval, which is used to throttle the tile update network requests.
Set the tile pre-fetching zoom delta for current source. Pre-fetching makes sure that a low-resolution tile at the (current_zoom_level - delta) is rendered as soon as possible at the expense of a little bandwidth. If delta has not been set or set to null, it will use the value in MapboxMap instance.
Set a flag defining whether or not the fetched tiles for the given source should be stored in the local cache
