绘制图像中的文本字体错误 (C#)

Question

我正在尝试编写代码，为给定的文本块输出 PNG 图像。我正在使用 System.Drawing 来实现这一点。

我的问题是输出图像中的文本字体错误。

这是我用来绘制输出的函数代码：

static Bitmap FromTextToPic(string text, Int16 size)
    {
        //create dummy Bitmap object
        Bitmap bitmapImage = new Bitmap(2, 2);

        //create dummy measurements
        int imageWidth = 0;
        int imageHeight = 0;

        //naming font
        font = "Lohit-Devanagari";

        // Creates the Font object for the image text drawing.
        System.Drawing.Font fontObject = new System.Drawing.Font(font, size, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Pixel);

        // Creates a graphics object to measure the text's width and height.
        Graphics graphicsObject = Graphics.FromImage(bitmapImage);

        // This is where the bitmap size is determined.
        imageWidth = (int)graphicsObject.MeasureString(text, fontObject).Width;
        imageHeight = (int)graphicsObject.MeasureString(text, fontObject).Height;

        // Creates the bmpImage again with the correct size for the text and font.
        bitmapImage = new Bitmap(bitmapImage, new Size(imageWidth, imageHeight));


        // Adds the colors to the new bitmap.
        graphicsObject = Graphics.FromImage(bitmapImage);

        // Sets Background color to white
        graphicsObject.Clear(System.Drawing.Color.White);

        //enables optimization for LCD screens
        graphicsObject.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighQuality;

        //enables antialiasing
        graphicsObject.TextRenderingHint = System.Drawing.Text.TextRenderingHint.AntiAlias; 

        //draws text to picture with black foreground color
        graphicsObject.DrawString(text, fontObject, new SolidBrush(System.Drawing.Color.Black), 0, 0, StringFormat.GenericDefault);

        graphicsObject.Flush();

        return (bitmapImage);
    }

即使我指定 "Lohit-Devanagari" 作为字体，我总是得到 "Mangal" 字体的输出（两者都是 Devanagari 字体）。那么，我做错了什么？

此外，如果文本中没有换行符（如 this picture），输出会延伸到很长的距离。有没有办法将输出图像包装成某个固定宽度？

而不是这个：

//naming font
font = "Lohit-Devanagari";

试试这个：

//naming font
FontFamily font = new FontFamily("Lohit Devanagari");

字体名称可能没有“-”字符。

如果你声明了一个新的对象FontFamily，如果字体没有它会抛出异常exist.So你必须下载并安装它...
