How to display a custom background instead of a fill color for shapes in Blazor Maps?

The Blazor Maps allow us to change the color of the geometry shape maps. You can also use an SVG pattern as a color for the shapes. This section will show you how to display an SVG pattern for the shapes in a custom map layer rendered in Maps.

To create your desired pattern, define an SVG pattern element in the razor page. To display the pattern style on the map layer’s custom shapes, set the id attribute of the SVG pattern element to the Fill property of the MapsShapeSettings of the MapsLayer.

The code example below shows how to display a custom background using an SVG pattern instead of a fill color for a custom shape map in Blazor Maps.

Index.razor

@using Syncfusion.Blazor.Maps

<svg>
    <defs xmlns="http://www.w3.org/2000/svg"><pattern id="lines" patternUnits="userSpaceOnUse" width="2" height="5" patternTransform="rotate(60)"><line x1="0" y="0" x2="0" y2="11" stroke="#194d33" stroke-width="2" /></pattern></defs>
</svg>

<SfMaps ID="Maps">
    <MapsZoomSettings Enable="true" ZoomFactor="4" MaxZoom="20"></MapsZoomSettings>
    <MapsCenterPosition Latitude="40.724546" Longitude="-73.850344"></MapsCenterPosition>
    <MapsLayers>
        <MapsLayer UrlTemplate=https://tile.openstreetmap.org/level/tileX/tileY.png TValue="string">
        </MapsLayer>
        <MapsLayer Type="Syncfusion.Blazor.Maps.Type.SubLayer" ShapeData='new {dataOptions= "simplegeo.json"}' TValue="string">
            <MapsShapeSettings Fill="url(#lines)">
                <MapsShapeBorder Color="Red" Width="5"></MapsShapeBorder>
            </MapsShapeSettings>
        </MapsLayer>
    </MapsLayers>
</SfMaps>
