Tiles covertion to Image formula! [help?]

Example..
Image/Tile | ingame x,y| image x,y
black tile | 8,39 | 384,112
pics1.png | 15,255 | 2048,512

NPC Code:



//Forumla

temp.tile = tiles[int(mousex),int(mousey)];

temp.tx = BLAH;

temp.ty = BLAH;



//Display of tile

showimg( 200, "pics1.png", screenwidth/2, screenheight/2);

changeimgvis( 200, 4);

changeimgpart( 200, temp.tx, temp.ty, 16, 16);

Basically I need help figuring out what I need to put in temp.tx and temp.ty to get the correct coords to get the image to display the tile the mouse is over.

I've been trying to do this for 2 days now, and I just can't figure out the correct formula ... So could anyone help me ..

I use this formula a lot when I'm doing external (or even internal!) programs/scripts that deal with Graal levels.

PHP Code:


		
			
base64 = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/";



temp.data = "aa";

temp.letters = {data.substring(0, 1), data.substring(1, 2)};



temp.tile = int((base64.pos(letters[0]) << 6) + base64.pos(letters[1]));



temp.tX = ((tile # 16) * 16) + (int(tile / 512) * 256);

temp.tY = tile # 512;

(Please replace # with a percent sign).

Your problem is a bit confusing, explain a little more in detail?
