from anymap_ts import Map

# Create sample data
points = {
    "type": "FeatureCollection",
    "features": [
        {
            "type": "Feature",

Get Layer IDs¶

In [ ]:

# List all layer IDs
layer_ids = m.get_layer_ids()
print("Layer IDs:", layer_ids)

# List all layer IDs layer_ids = m.get_layer_ids() print("Layer IDs:", layer_ids)

Get Layer Configuration¶

In [ ]:

# Get configuration for a specific layer
layer_config = m.get_layer("points")
print("Points layer config:", layer_config)

# Get configuration for a specific layer layer_config = m.get_layer("points") print("Points layer config:", layer_config)

Set Paint Properties¶

In [ ]:

# Change the circle color dynamically
m.set_paint_property("points", "circle-color", "#00ff00")
m.set_paint_property("points", "circle-radius", 12)

# Change the circle color dynamically m.set_paint_property("points", "circle-color", "#00ff00") m.set_paint_property("points", "circle-radius", 12)

Set Layout Properties¶

In [ ]:

# Toggle layer visibility
m.set_layout_property("zones", "visibility", "none")

# Toggle layer visibility m.set_layout_property("zones", "visibility", "none")

In [ ]:

# Show the layer again
m.set_layout_property("zones", "visibility", "visible")

# Show the layer again m.set_layout_property("zones", "visibility", "visible")

Move Layer Order¶

In [ ]:

# Move points layer below zones layer
m.move_layer("points", "zones")

# Move points layer below zones layer m.move_layer("points", "zones")

In [ ]:

# Move points back to top
m.move_layer("points")

# Move points back to top m.move_layer("points")

Set Visibility and Opacity¶

In [ ]:

# Set layer opacity
m.set_opacity("zones", 0.7)

# Set layer opacity m.set_opacity("zones", 0.7)

In [ ]:

# Toggle visibility
m.set_visibility("points", False)

# Toggle visibility m.set_visibility("points", False)

In [ ]:

# Show again
m.set_visibility("points", True)

# Show again m.set_visibility("points", True)
