我正在尝试编写一个代码,用于为给定的文本块输出PNG图像。我正在使用System.Drawing来实现此目的。绘制图像中的文本字体错误(C#)

我的问题是,输出图像中的文本是错误的字体。

下面是我使用,以得出输出函数的代码:

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); 
    } 

即使当我指定“嘉黎,梵文”的字体,我总是得到输出以“Mangal”字体(都是梵文字体)。那么,我做错了什么?

此外,如果文本中没有换行符(如this picture),则输出延伸到很远的距离。有没有办法将输出图像合并到某个固定的宽度?

取而代之的是:

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

试试这个:

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

的字体名称可能是没有 “ - ” 字符。

如果要声明一个新对象的FontFamily,它会使一个异常,如果字体不exist.So你必须下载并安装它...
