Introduction
In this article we will examine how to create a custom marker with using the GFX library. In the example we will create a transparent ellipse, which the user can drag around the map.
Prerequisites
Nokia Maps API supported web browser (basically any modern web browser)
Important about Maps credentials
With Nokia Maps API you can start without having any credentials given, but you might face a performance gap. In order to get the full potential out of the offering, you must get the credentials that authenticate your application against the Services. Please read through the Location API.
For more information on how to obtain the credentials, please start with the Nokiai Maps API Developers Guide section "Acquiring API credentials"
Implementation
We will create a map with the set of basic user controls, and center the map with a zoom level. The testLayer refers to a new map Container we create. We then add the container to the map objects and graphicsContext variable will have an instance of the GFX library Graphics object.
Example code
Please note the images are being zoomed to be visible on the current zoom level. However, you would need to zoom in more towards the images to see the ones that maybe layered under the top images.

var graphicsContext = new nokia.maps.gfx.Graphics();
graphicsContext.beginImage(64,64);
// Compress a semi-transparent red color
var my_fill_color = nokia.maps.gfx.Color.compress(255, 0, 0, 127);
graphicsContext.set("fillColor", my_fill_color);
graphicsContext.set("strokeColor", "#000");
graphicsContext.set("lineWidth", 4);
graphicsContext.drawEllipse(1, 1, 48, 48);
graphicsContext.fill();
graphicsContext.stroke();
var myGfxMarker = new nokia.maps.map.Marker(
{latitude:19.119, longitude:72.8957},
{
icon: new nokia.maps.gfx.GraphicsImage(graphicsContext.getIDL()),
visibility: true,
