Note

Bing Maps Web Control SDK retirement

Bing Maps Web Control SDK is deprecated and will be retired. Free (Basic) account customers can continue to use Bing Maps Web Control SDK until June 30th, 2025. Enterprise account customers can continue to use Bing Maps Web Control SDK until June 30th, 2028. To avoid service disruptions, all implementations using Bing Maps Web Control SDK will need to be updated to use Azure Maps Web SDK by the retirement date that applies to your Bing Maps for Enterprise account type. For detailed migration guidance, see Migrate from Bing Maps Web Control SDK and Migrate Bing Maps Enterprise applications to Azure Maps with GitHub Copilot.

Azure Maps is Microsoft's next-generation maps and geospatial services for developers. Azure Maps has many of the same features as Bing Maps for Enterprise, and more. To get started with Azure Maps, create a free Azure subscription and an Azure Maps account. For more information about azure Maps, see Azure Maps Documentation. For migration guidance, see Bing Maps Migration Overview.

Creating an instance of the Color class can be done in one of two ways. The first is to specify values for all the properties in the constructor. The second is to use the static method fromHex which parses a string Hex color value into a Bing Maps Color. The following code shows how these two methods can be used to create a Location objects.

Note: In addition to using the Color class to specify the color of a shape in Bing Maps, CSS3 color strings can also be used.

Constructor

Color(a: number, r:number, g:number, b:number)

Properties

The Color class has four properties; a (alpha), r (red), g (green), b (blue) and are defined as follows.

Name Type Description
a number The opacity of the color. The range of valid values is a decimal value between 0 and 1. If a value between 1 and 255 is specified, as was done in Bing Maps V7, it will be divided by 255.
r number The red value of the color. The range of valid values is 0 to 255.
g number The green value of the color. The range of valid values is 0 to 255.
b number The blue value of the color. The range of valid values is 0 to 255.

Methods

The Color class has the following methods available.

Name Return Type Description
clone() Color Returns a copy of the Color object.
getOpacity() number Returns the opacity of the Color as a value between 0 (a=0) and 1 (a=255).
toHex() string Converts the Color into a 6-digit hex string. Opacity is ignored. For example, a Color with values (255,0,0,0) is returned as hex string #000000.
toRgba() string Converts the Color into a RGBA color string. For example: rgba(0, 255, 0, 0.5)
