how to add text to a map (Item)

Hi,
Does anybody know how to add a text to a map ? When you hold a map in your hand there is a text instead of the map.
Is it an API ? If so, where do i find this API ..

Thanks in advance,
Best regards

 

You have to get the MapCanvas of the map, and use setPixel(int x, int y, byte color); to change do that

MapCanvas

 

drawText(int x, int y, MapFont font, String text) would be easier if its text...

 

I did not even see that method, thank you

 

Thanks for your answers. But how to do this ? I dont want every map to have a text. Is this possible or does everymap has the text ?
How to call this "method" ? It's not an event or something ..

Maybe just a simple Code snippet ?

Code:

MapView map = Bukkit.getServer().getMap(<iteminhand>.getDurability());
for (MapRenderer mr : map.getRenderers()){
    map.removeRenderer(mr);
}
map.addRenderer(yourCustomRenderer);
