I'm not aware of any limitations on the snapshot. Would you mind sharing a code snippet?
I wrote this code:
var pathArr = [CLLocationCoordinate2D]()
for workoutLocation in self.workoutLocations {
pathArr.append(workoutLocation.coordinate)
}
var path = Path(coordinates: pathArr)
path.strokeWidth = 2
path.strokeColor = .black
let options = SnapshotOptions(
styleURL: URL(string: "mapbox://styles/r****")!,
size: CGSize(width: 200, height: 200))
options.overlays = [path]
let snapshot = Snapshot(
options: options,
accessToken: "****")
snapshot.image { (image, error) in
let img: UIImage = image!
print("")
}
I don't see any issues when using 3000 coordinates but I start getting "MBStaticErrorDomain Code=-1 server errors" after 4000. Might be due to the custom style. @1ec5 do you know if we have any hard limitations on the number of coordinates in a path?
If you are using the Maps SDK for iOS, it might be of interest to use the newly introduced MGLMapSnaphotter which renders the snapshot client side.
How can I set path overlay to MGLMapSnapshotOptions
?
Thank you
You would have to add an MGLPolylineFeature
to the map view itself. Similar to https://www.mapbox.com/ios-sdk/examples/line-geojson/
Sorry but I don't have a map view. I only have an array of CLLocationCoordinate2D
and I would get an image of the map fragment with the overlay path.

Ok, then the static api is the way to go. Trying to figure out if there is a limit.
do you know if we have any hard limitations on the number of coordinates in a path?
Not on the number of coordinates specifically, but according to the Static API documentation, there is a restriction on the number of features in a GeoJSON overlay, as well as a restriction on the length of the string encoding of all the overlays combined:
Overlays cannot consist of more than 100 features. The maximum overlay length is 2083 characters.
A Path
’s string-encoded length depends on the Polyline encoding of all the coordinates, plus any styling options.
Hi, a long time passed, how is this issue going?
Do we have any number of limit coordinates to pass to the Path
?
Hi, is there a limit to coordinates array length to build a path overlay? I need to draw about 3000
CLLocationCoordinate2D
on the map, but i'm gettingMBStaticErrorDomain" - code: 18446744073709551615
when getting image fromSnapshot
object. Until 1500CLLocationCoordinate2D
works well, I'm getting right the map.Thank you.
