To colorize the map using a key-color colorizer, do the following.
Form1.cs |
VectorItemsLayer hotelLayer = new VectorItemsLayer() {
Data = CreateData(),
Colorizer = CreateColorizer()
};
map.Layers.Add(hotelLayer);
private MapColorizer CreateColorizer() {
KeyColorColorizer colorizer = new KeyColorColorizer() {
ItemKeyProvider = new AttributeItemKeyProvider() { AttributeName = "CATEGORY" },
PredefinedColorSchema = PredefinedColorSchema.Palette
};
colorizer.Keys.Add(new ColorizerKeyItem() { Key = 1, Name = "Restaurant" });
colorizer.Keys.Add(new ColorizerKeyItem() { Key = 2, Name = "Business room" });
colorizer.Keys.Add(new ColorizerKeyItem() { Key = 3, Name = "Bathroom" });
colorizer.Keys.Add(new ColorizerKeyItem() { Key = 4, Name = "Living room" });
colorizer.Keys.Add(new ColorizerKeyItem() { Key = 5, Name = "Other" });
colorizer.Keys.Add(new ColorizerKeyItem() { Key = 6, Name = "Service room" });
colorizer.Keys.Add(new ColorizerKeyItem() { Key = 7, Name = "Pool" });
colorizer.Keys.Add(new ColorizerKeyItem() { Key = 8, Name = "Gym" });
return colorizer;
}
