我正在嘗試編寫一個代碼,用於爲給定的文本塊輸出PNG圖像。我正在使用System.Drawing來實現此目的。繪製圖像中的文本字體錯誤(C#)

我的問題是,輸出圖像中的文本是錯誤的字體。

下面是我使用,以得出輸出函數的代碼:

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); 
    } 

即使當我指定「嘉黎,梵文」的字體,我總是得到輸出以「Mangal」字體(都是梵文字體)。那麼,我做錯了什麼?

此外,如果文本中沒有換行符(如this picture),則輸出延伸到很遠的距離。有沒有辦法將輸出圖像合併到某個固定的寬度?

取而代之的是:

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

試試這個:

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

的字體名稱可能是沒有 「 - 」 字符。

如果要聲明一個新對象的FontFamily,它會使一個異常,如果字體不exist.So你必須下載並安裝它...

非常感謝。解決了這個問題。 – roboPoco 2015-02-24 03:58:46
