如何在 emgucv 中使用自定义字体？

Question

我知道如何在 Emgu CV 中的图像上绘制文本：

CvFont f = new MCvFont(Emgu.CV.CvEnum.FONT.CV_FONT_HERSHEY_COMPLEX_SMALL, 1, 1);
image.Draw("something", ref f, new Point(0, 0), new Rgb(0, 0, 0));

但我不知道如何使用其他字体代替 CV_FONT_HARSHEY*

更新：

这是完整的解决方案：

var b = image.Bitmap;
Graphics g = Graphics.FromImage(b);
Font drawFont = new Font("Arial", 16);
SolidBrush drawBrush = new SolidBrush(Color.Black);
PointF drawPoint = new PointF(0,0);
g.DrawString("something,", drawFont, drawBrush, drawPoint);

/// after drawing etc.

image.Bitmap = b;

Answer 1

您可以在PrivateFontCollection中添加 TTF 文件

// 'PrivateFontCollection' is in the 'System.Drawing.Text' namespace
var foo = new PrivateFontCollection();
// Provide the path to the font on the filesystem
foo.AddFontFile("...");

var myCustomFont = new Font((FontFamily)foo.Families[0], 36f);

然后你画这样的图像：

image.Draw("something", myCustomFont, new Point(0, 0), new Rgb(0, 0, 0));

或者您可以使用 myCustomFont 中的方法： Graphics.DrawString

// 此解决方案在 Mat 图像上绘制测试

{   
    var b = myMat.ToBitmap();  
    Graphics g = Graphics.FromImage(b);
    Font drawMFont = new Font("Calibri", 8, FontStyle.Bold);
    SolidBrush drawMBrush = new SolidBrush(Color.DarkCyan); 
    PointF drawMPoint = new PointF(1, 4);
    g.DrawString("Hello",drawMFont,drawMBrush, drawMPoint);
}
