在圖像上書寫3維文字

Question

是否可以在圖像上書寫3D文字。我正在使用asp.net與c＃。如果可能的話，請給我一些想法。

這裏是我的方法寫在圖像

 

private readonly string _textOnImage = ConfigurationManager.AppSettings["textOnImage"]; 
private readonly int _opacity = Int32.Parse(ConfigurationManager.AppSettings["opicity"]); 
private readonly int _red = Int32.Parse(ConfigurationManager.AppSettings["red"]); 
private readonly int _green = Int32.Parse(ConfigurationManager.AppSettings["green"]); 
private readonly int _blue = Int32.Parse(ConfigurationManager.AppSettings["blue"]); 
private int _fontSize = Int32.Parse(ConfigurationManager.AppSettings["fontSize"]); 
private readonly String _fontName = ConfigurationManager.AppSettings["fontName"];
 

private bool _havException { get; set; } 
private string _exceptionMessage { get; set; } 
private Bitmap SourceImage { get; set; } 
private Bitmap DestinationImage { get; set; } 
public ImageMethods() 
{ 
    _havException = false; 
    _exceptionMessage = string.Empty; 
}
 

public void AddWatermarkText(Image img, String TextOnImage) 
    { 
     TextOnImage = TextOnImage ?? _textOnImage; 

     try 
     { 
      var lobFromImage = Graphics.FromImage(img); 
      FindFontSize(lobFromImage, img, TextOnImage); 
      var lobFont = new Font(_fontName, _fontSize, FontStyle.Regular); 


      var lintTextHw = lobFromImage.MeasureString(TextOnImage, lobFont); 
      var lintTextOnImageWidth = (int)lintTextHw.Width; 
      var lintTextOnImageHeight = (int)lintTextHw.Height; 

      var lobSolidBrush = new SolidBrush(Color.FromArgb(_opacity, Color.FromArgb(_red, _green, _blue))); 

      var posLeft = (img.Width - lintTextOnImageWidth)/2; 
      posLeft = posLeft > 0 ? posLeft : 5; 
      var lobPoint = new Point(posLeft, (img.Height/2) - (lintTextOnImageHeight/2)); 

      // var lobPoint = new Point(RandomNumber(0, img.Width - lintTextOnImageWidth), RandomNumber(0, img.Height - lintTextOnImageHeight)); 
      lobFromImage.DrawString(TextOnImage, lobFont, lobSolidBrush, lobPoint, StringFormat.GenericTypographic); 

      lobFromImage.Dispose(); 
      lobSolidBrush.Dispose(); 
      lobFont.Dispose(); 
     } 
     catch (Exception ex) 
     { 
      _havException = true; 
      _exceptionMessage = ex.Message; 
     } 
     return; 
    } 
    private void FindFontSize(Graphics lobGraphics, Image lobImage ,String textOnImage) 
    { 
     var lobFont = new Font(_fontName, _fontSize, FontStyle.Regular); 
     var lintTextHw = lobGraphics.MeasureString(textOnImage, lobFont); 
     var lintTextOnImageWidth = (int)lintTextHw.Width; 
     var lintImageWidth = lobImage.Width ; 
     while (lintImageWidth < lintTextOnImageWidth) 
     { 
      lobFont = new Font(_fontName, _fontSize--, FontStyle.Regular); 
      lintTextOnImageWidth = (int)lobGraphics.MeasureString(textOnImage, lobFont).Width; 
     } 
    }

是的，這是可能的文本，但你必須手工繪製。

請參閱this開始繪製圖像。

接下來，探索System.Drawing命名空間，特別是Graphics類，它具有繪製方法並用於上述文章中。
