minimap tiling

[CrimeTime]

Hey guys,

I'm currently working on tiling the minimap on a radar in c#, the loading of the tiles works pretty good at the moment, but there's a problem with algining the minimap with the players position.

Here a snapshot from the minimap of wow:

and here from the radar:

Like displayed on the screenshots, you can see that the position of the minimap isn't right in the radar.

I'm using the code from jbraumann's radar source to draw/load the minimap tiles into the radar.

This is the code of the function what algin the minimap with the players location:

        private static Bitmap DrawMinimapOverlay(Bitmap img, Bitmap RadBit)
        {

            Graphics G = Graphics.FromImage(RadBit);

            int cellBindpointX = (int)((((Math.Abs(ObjectMgr.LocalPlayer.X) % TILE_SCALE_FACTOR) / TILE_SCALE_FACTOR) * ZoomFactor) * 1);
            int cellBindpointY = (int)((((Math.Abs(ObjectMgr.LocalPlayer.Y) % TILE_SCALE_FACTOR) / TILE_SCALE_FACTOR) * ZoomFactor) * 1);

            if (ObjectMgr.LocalPlayer.X <= 0 && ObjectMgr.LocalPlayer.Y <= 0)
            {
                G.DrawImage(img, ((int)((RadarWidth) / 2) - cellBindpointX) - 1 * ZoomFactor, ((int)((RadarHeight) / 2) - cellBindpointY) - 1 * ZoomFactor);
            }
            else if (ObjectMgr.LocalPlayer.X >= 0 && ObjectMgr.LocalPlayer.Y <= 0)
            {
                G.DrawImage(img, ((int)((RadarWidth) / 2) + (cellBindpointX - ZoomFactor)) - 1 * ZoomFactor, ((int)((RadarHeight) / 2) - cellBindpointY) - 1 * ZoomFactor);
            }
            else if (ObjectMgr.LocalPlayer.X <= 0 && ObjectMgr.LocalPlayer.Y >= 0)
            {
                G.DrawImage(img, ((int)((RadarWidth) / 2) - cellBindpointX) - 1 * ZoomFactor, ((int)((RadarHeight) / 2) + (cellBindpointY - ZoomFactor)) - 1 * ZoomFactor);
            }
            else if (ObjectMgr.LocalPlayer.X >= 0 && ObjectMgr.LocalPlayer.Y >= 0)
            {
                G.DrawImage(img, ((int)((RadarWidth) / 2) + (cellBindpointX - ZoomFactor)) - 1 * ZoomFactor, ((int)((RadarHeight) / 2) + (cellBindpointY - ZoomFactor)) - 1 * ZoomFactor);
            }

            return img;
        }

The underlined if clause is used everytime, but the algin of the drawing of it has a high wrongness.
Thats why I used the code in bold to make the screenshots above.

sorry for my broken english, its not my home country language.
