Request: Light silhouette

[ChibiChibiLuc]

Yeah.. I don't really know what to call this, but..

Is there any way a command could be added that gives an image a light effect, but only the silhouette?

For example:

NPC Code:

---

function onCreated() {

  showimg(300, "light4.png", x, y); 

  changeimgcolors2(300, 1, 0, 0, 1);

}

---

It turns the non-transparent parts of the image pure red, instead of just tinting it.

I know I explained this badly.. Does anyone understand what I mean?
