Custom Marker Position Issue when Zoom In and Out

[Arthur Liew]

Hi, I am using the latest Xamarin and Syncfusion library version for the development.  I created a few custom markers with specific latitude longitude, however, when it is zoomed out, the marker position is not accurate.  When it zoomed in, it will be more accurate.  I am using the default OSM map, would like to stick with OSM rather than Google.

As the file size is larger than the limit size, I attached the solution through google drive.

Hi Arthur Liew,  

 

Greetings from Syncfusion, 

 

We checked the reported issue “Custom marker is not placed accurately in OSM” and we would like to inform you that we place the marker in center of the given geo point. So, if you give custom marker like pin image, it looks like not accurate when decrease the zoom level. 

 

We can fix this by setting the VerticalAlignment property as near in the marker settings. Please refer below link to know how to set VerticalAlignment property.

Hi Eswaran,

I attached a new link with my current progress:

I used the sample you gave to me, it works, however, I have one Label that indicates the country name, it has a gap when it zoomed out, and the gap is slowly tighter when I zoomed in.  

May I know what's causing it?

Hi Arthur Liew,

Thanks for sharing the sample.

We have checked the reported problem with the shared sample and working fine at our end.

The equal space is maintained between the label and a marker pin icon in each zoom level.

We have prepared a video for your requirement.  Please have a video from the below link.
