Thanks for your reply, I have achieve desired finicality using custom font and CharacterPointSymbolizer.
  private SharpMap.Styles.VectorStyle GetCustomStyle(SharpMap.Data.FeatureDataRow row)
            SharpMap.Styles.VectorStyle style = new SharpMap.Styles.VectorStyle();
            var ps = new CharacterPointSymbolizer();
            ps.CharacterIndex = 0x63;
            //ps.Font = new Font(pfc.Families[0], 42, FontStyle.Regular);

            ps.Font = new Font(pfc.Families[0], 42, FontStyle.Regular, GraphicsUnit.Pixel, 0x63, false);
            //ps.Foreground = new LinearGradientBrush(
            //                                           new Rectangle(0,0,32,32),
            //                                           Color.FromArgb(255, 255, 0, 0),   // Opaque red
            //                                           Color.FromArgb(255, 0, 0, 0), (float)(Convert.ToDecimal(row.ItemArray[5])), true);        
            ps.Offset = new Point(0, 10);
            ps.Rotation =(float)(Convert.ToDecimal(row.ItemArray[5]));
            ps.Halo = 100;            
            style.PointSymbolizer = ps;            
            return style;
But issue is how to set background with gradient color for each point

Still I don't get what you want. You are talking about points and show us a polygons.

What exactly are you trying to achieve?

if you want a polygon that remains the same size on the screen, you could use a decoration instead?
