View source for API:DynamicImageSetRotation

{{LuaApi|group=DynamicImage}}
Rotates the picture shown by a DynamicImage.

<pre>
DynamicImageSetRotation(imageName, angle)
</pre>

== Arguments ==
;imageName : <code>string</code> – Name of a DynamicImage window.
;angle : <code>number</code> – Rotation angle in degrees.

== Returns ==
Nothing.

== Details ==
* The client converts the angle to radians. If it equals the current angle, nothing happens.
* The function needs at least two arguments and only reads the last two.

== Errors ==
* <code>Error in function call 'DynamicImageSetRotation': Window %s does not exist</code>
* <code>Error in function call 'DynamicImageSetRotation': Window %s is not a DynamicImage</code>

== Example ==
Turning a gauge needle, from <code>ea_careerresourceswindow/source/choppa.lua</code>:
<pre>
local rotationModifier = 180 / g_resource_max
local rotate = ( currentResourceValue * rotationModifier ) - 90
if ( rotate < 0 )
then
    rotate = 360 + rotate
end

DynamicImageSetRotation( g_resource_window.."Needle", rotate )
</pre>
