Question

是否可以在图像上书写3D文字。我在使用带有c＃的asp.net。如果可能的话，请给我一些想法。

这是我在图像上写文字的方法



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，这是可能的，但您必须手动绘制。

请参阅this开始绘制图片。

接下来，探索System.Drawing命名空间，特别是具有绘制方法的Graphics类，并在上述帖子中使用。
