surface.drawtexturedrectrotated half invisible. How to?

[RANDOMlagFTW]

So ive Been fiddling around with a compass, i have a texture which is a full circle with N W S E, and i was wondering if i could cut out the bottom part so only the top part of the compass is visible. How would i go on about doing that.

Get 2 textures, one half invisible on top, one half invisible on bottom.

I don't understand how that would work in my case. Tho I might be dumb.

The compass rotates the circle texture depending where the client is looking at.

Here's the code for reference:

local x, y = ScrW()/2, ScrH()/2
local ang = LocalPlayer():GetAimVector():Angle().y
local h, w = 200, 200
local x2, y2 = x+(w/2), y+(h/2)

surface.SetDrawColor(255,255,255,150)
surface.SetMaterial(Material("icons/compass_letters.png"))
surface.DrawTexturedRectRotated(x2,y2,w,h,ang)

It's pretty self explanatory, but I'm not quite sure if it'd work with rotated textures... it probably would though, give it a shot
