添加到图像的文本在边缘被切断

Question

我正在尝试在图像上添加文字，如果文字很短，效果很好。但是，如果我添加更长的文本，它将在边缘被切断。

如果文本太长，我需要换行。

这是我目前的代码：

Graphics graphicImage = Graphics.FromImage(bitMapImage);

//Smooth graphics is nice.
graphicImage.SmoothingMode = SmoothingMode.AntiAlias;
Font font = new Font("Tahoma", 6);
int x_axis = 50;
int y_axis = 120;
int distance = 50;
graphicImage.DrawString("This is a very long text and this long text might come to a new line below", font, Brushes.Yellow, new PointF(x_axis, y_axis + distance * 2));

String tempFile = folder + "output.jpeg";
bitMapImage.Save(tempFile, ImageFormat.Jpeg);

这是它创建的图像

如何让文字换行？

Answer 1

在一个矩形中绘制文本，它会自动换行：

string text1 = "Draw `enter code here`text in a rectangle by passing a RectF to the DrawString method.";
using (Font font1 = new Font("Arial", 12, FontStyle.Bold, GraphicsUnit.Point))
{
    RectangleF rectF1 = new RectangleF(30, 10, 100, 122);
    e.Graphics.DrawString(text1, font1, Brushes.Blue, rectF1);
    e.Graphics.DrawRectangle(Pens.Black, Rectangle.Round(rectF1));
}
