rotating player in minimap

Im trying to rotate player icon according to players facing.

                Image pImage = Image.FromFile("player.png");
                Bitmap pBitmap = new Bitmap(pImage.Width, pImage.Height);
                Graphics gfx = Graphics.FromImage(pBitmap);
                gfx.RotateTransform(10);
                gfx.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic;
                gfx.DrawImage(pImage, new Point(0, 0));
                gfx.Dispose();

                g.DrawImage(pImage, 150 - RADAR_ICON_WIDTH / 2, 150 - RADAR_ICON_HEIGHT / 2, RADAR_ICON_WIDTH, RADAR_ICON_HEIGHT);

the following code does not rotate at all :( the player.png (a arrowicon) is only pointing upwards (default position) at all times :(

Solution

  • After a little searching the web i found these two sites:

    If i take a look into these codes it seems that you are missing a call to TranslateTransform before and after calling RotateTransform.
