Release R1 2023 SP1

Good Afternoon,

we use the RadMap's SelectionRectangleChanged event to allow the user to (de)select map elements with the box. In the event handler we use the layer's GetItemsInRectangle function to see what is within the selected area but this is where we encounter a problem with LineData objects. Dragging a selection rectangle that does not touch an edge but is close enough to it (likely within the bounding box of the LineData) it incorrectly recognizes the line as within the rectangle. See the attached screenshot for an example of a selection rectangle that should contain no elements within but actually reports the long line to its right as an element it contains. This can also be reproduced with the attached project:

  • Ctrl + Mouse Left to drag a selection rectangle
  • Mouse Left to pan, mouse wheel zo zoom. Shift + Mouse Left for zoom rectangle
  1. Draw a selection rectangle on the very left or right outside the elements: Debug Output reports "Selected Edges: 0"
  2. Draw a selection rectangle close to an edge but not touching it: Debug Output reports "Selected Edges: 1"
  3. Draw selection rectangle that contains (parts of) an edge: Debug Output reports "Selected Edges: 1"

Regards
Dominik Schacht

Hello,

after setting the `ZoomStep` in our project to something smaller than 1 (a feature we are very pleased to receive in the latest update) we encountered a problem when zooming in and out of our map view. I have attached screenshots and an example project to reproduce the issue. It occurs wether the renderer is set to SoftwareOnly or default.

Steps to reproduce:

  1. Start the example project (MapZoomInitial.png)
  2. Scroll the mouse wheel one click in to zoom in one step
  3. Scroll the mouse wheel one click out to zoom out again
  4. Artifacts appear (MapViewAfterZoomInAndOut.png)

Using wraparound True and Virtualization in VisualizationLayer.
When panning from left to right and placing rectangles over the requested regions, a gap could be seen on the left side. This is because the regions that get into viewport fire data request event when their top left point is inside the viewport. To cover the viewport, the topright point of the regions should be used instead.

Recently OpenStreetMap changed their tile usage policy and require UserAgent string in the web headers for accessing tile.openstreetmap.org tiles.

https://operations.osmfoundation.org/policies/tiles/

As a result, standard open street map mode does not work - no tiles are loaded and "too many requests" error is returned from the server.

RadMap's OpenStreetMapProvider needs API (event, property or similar) for easier set up of UserAgent / Referer / other headers of web requests.

Currently, the workaround is to override the OpenStreetMapProvider like so:

    public class CustomOpenStreetProvider : OpenStreetMapProvider
    {
        public CustomOpenStreetProvider()
        {
            OpenStreetMapnikSource osmMapInkSource = this.MapSources.Values.ToList()[0] as OpenStreetMapnikSource;
            if (osmMapInkSource != null)
            {
                osmMapInkSource.WebHeaders.Add(System.Net.HttpRequestHeader.UserAgent, "your custom user agent string");
            }
        }
    }

If you update the Location of a map shape data object (for example, EllipseData, PolygonData, ect.) at run-time, while the clustering feature is enabled, the shape disappears.

To work this around, reset the clustering via the IsClusteringEnabled property when the Location changes.

this.ellipseShapeData = new Location(newLatitude, newLongitude);
this.visualizationLayer.ClusteringEnabled = false;
this.visualizationLayer.ClusteringEnabled = true;
