如何返回字体族给定索引的字符

要绘制字符,可以使用以下代码片段:

public static Image DawTextFromFontFamily(string text, FontFamily family, Color textColor, Color backColor)
{
     return DrawText(text, new Font(family, 16), textColor, backColor);
}

public static Image DrawText(String text, Font font, Color textColor, Color backColor)
{
        //first, create a dummy bitmap just to get a graphics object
        Image img = new Bitmap(1, 1);
        Graphics drawing = Graphics.FromImage(img);

        //measure the string to see how big the image needs to be
        SizeF textSize = drawing.MeasureString(text, font);

        //free up the dummy image and old graphics object
        img.Dispose();
        drawing.Dispose();

        //create a new image of the right size
        img = new Bitmap((int)textSize.Width, (int)textSize.Height);

        drawing = Graphics.FromImage(img);

        //paint the background
        drawing.Clear(backColor);

        //create a brush for the text
        Brush textBrush = new SolidBrush(textColor);

        drawing.DrawString(text, font, textBrush, 0, 0);

        drawing.Save();

        textBrush.Dispose();
        drawing.Dispose();

        return img;
}

现在你有了一个图像,任何字符,你需要的字体
