This sample illustrates the utilization of a pre-defined icon template as a symbol layer in Azure Maps. The Azure Maps Web SDK offers a variety of icon templates for selection.
These templates allow you to personalize the icons by specifying primary and secondary colors according to your preferences.
Furthermore, the icons can be scaled prior to their inclusion in the maps image manager.
To ensure optimal visual quality, it is advisable to scale the icon templates to their maximum desired size, add them to the map, and subsequently scale them down during layer rendering. This approach prevents the icons from appearing blurry or distorted.
