當遇到要將文字PNG的時候,可以使用這邊所提供的Function
這隻Function做到的是輸出最符合文字大小的PNG檔

private void DrawFont2PNG(String Font, int FontSize,String Path,String Name,String Text)
{
    Bitmap newBitmap = null;
    Graphics g = null;
//Font Example:”新細明體”
    Font fontCounter = new Font(Font,FontSize));
    // calculate size of the string.         
 newBitmap = new Bitmap(1, 1, PixelFormat.Format32bppArgb);
    g = Graphics.FromImage(newBitmap);
    //g.TextRenderingHint = System.Drawing.Text.TextRenderingHint.ClearTypeGridFit;          SizeF stringSize = g.MeasureString(Text, fontCounter);
    int nWidth = (int)stringSize.Width;
    int nHeight = (int)stringSize.Height;
    g.Dispose();
    newBitmap.Dispose();
    newBitmap = new Bitmap(nWidth, nHeight, PixelFormat.Format32bppArgb);
    g = Graphics.FromImage(newBitmap);
    g.FillRectangle(new SolidBrush(Color.White),new Rectangle(0, 0, nWidth, nHeight));
    g.DrawString(Text ,fontCounter,new SolidBrush(Color.Black), 0, 0);
    newBitmap.MakeTransparent(Color.White);
    newBitmap.Save(Path+Name+".png", ImageFormat.Png);
}
