Thank you very much for this fine library.

It seems like a marker it getting shifted up the smaller the zoom is, i.e. for zoom 12 the marker position seems good. If I decrease the zoom stepwise to smaller numbers, the marker will be positioned above (and more left) of the given coordinates.

In the following images the zoom is decreased from 12 to 8, 6 and 4. At zoom 4 the marker is almost at germanys norther border, but the coordinates point to a place way south.

My setup is rather simple

$tempFilePath = tempnam(sys_get_temp_dir(), 'osm');
$markerPath = $this->parameterBag->get('kernel.project_dir').'/assets/images/marker-black.png';

$markers = (new Markers($markerPath))
    ->setAnchor(Markers::ANCHOR_CENTER, Markers::ANCHOR_BOTTOM)
    ->addMarker(new LatLng($lat, $lng));

$map = (new OpenStreetMap(new LatLng($lat, $lng), $zoom, 640, 640))
    ->addMarkers($markers);

$map->getImage()->savePNG($tempFilePath);

I had a quick look at Markers::draw() but could not find the problem.

Edit: The marker anchor position does not seem to have anything to do with the misplacement.

Initially when I first used this package it worked just fine with any coordinates, but I had to update my php version to 8 to accommodate other needs of my project and I'm not sure if that has anything to do with this but it now has stopped working like before mainly that the base map(tileServer?) doesn't show up anymore but the drawing of the spatial shapes still functions and the display/save options work as well!

Here's how it looks:

Would it be possible to draw a circle on the map, like in this example:

I saw that your Image class in php-image-editor has a drawCircle method, but I'm not sure how to use it to draw on a map image. Thanks for any pointers.

OpenStreetMap based maps need attribution, see: https://openstreetmap.org/

It would be nice to add it automatically in the corner of the generated PNG.

Merci d'avance !

First of all: Thanks for this amazing library. I have added support for tile servers other than OpenStreetMaps. I made sure, that its backwards compatible.

The update for the technical documentation is missing, maybe you can run the phpDocumentor.

Maybe you can also give me some instructions on how you want to have the documentation for the new feature in the readme file.

Hi, Great little library you have! I've began testing it yesterday.

As I was testing it, I noticed it didn't have much in the way of error checking on specifically the image retrieval. A good example is when you put a typo in the TileLayer construct for the url use "https://tilezzzzzz.openstreetmap.org/{z}/{x}/{y}.png". The image will get displayed with a grey background with nothing on it. Some people may want it to function like this.

As such, made a construct option called failCurlOnError, and allowed curl option arrays in order to have more flexibility.

In my use case, if there is a failure, I have the code falling back to another method.

Thanks!

Great Job!

What is the projection of the lat lon variables?

I have tried to put my town (Burriana/Castellon/Spain) and I see my marker on Africa

Thank you

Hey, great project! I researched the topic of static maps as well, thought about using this approach for a wordpress gutenberg block maybe.

During my research I stumbled about the fact, that Open Streetmap data is free for everyone to use, but tile servers are run by donations and have restrictions (It is also possible to setup own tile server or use commercial hosted services).

Just added this line to make sure you give users all the necessary information on restrictions. :-)

Best regards
