New page

{{LuaApi|group=Interface}}
Returns the texture coordinates and size of a map icon.

<pre>
x, y, width, height = GetMapIconData(mapIconId)
</pre>

== Arguments ==
;mapIconId : <code>number</code> – Map icon id, for example the <code>mapIcon</code> field of map point data.

== Returns ==
;x, y : <code>number</code> – Position of the icon in the map marker texture.
;width, height : <code>number</code> – Size of the icon.

== Details ==
* The id is converted to an integer and looked up in the client's map icon table.
* If the id is not in the table, an error message is logged and the function returns <code>0, 0, 0, 0</code>.
* The stock UI uses the values with the <code>map_markers01</code> texture.

== Errors ==
* <code>Error in function call 'GetMapIconData': Map Icon id is invalid - %d</code>

== Example ==
From <code>easystem_tooltips/source/maptooltips.lua</code>:
<pre>
textureX, textureY, sizeX, sizeY = GetMapIconData( ptData.mapIcon )
-- Clear the slice on the dynamic image. DynamicImageSetTexture will not work
-- correctly if a slice is assigned.
DynamicImageSetTextureSlice( iconWindow, "" )
DynamicImageSetTexture( iconWindow, "map_markers01", textureX, textureY )
...
DynamicImageSetTextureDimensions( iconWindow, sizeX, sizeY )
</pre>
