我可以写在图像搜索文本
但我会写在不同的位置更多的文本

推荐答案

要绘制多个字符串叫拉绳多的时候，你可以指定绘制字符串的位置。本例中我们得出两个字符串Hello，字（你好，在蓝色的前期字的红色）：

To draw multiple strings call draw string multiple time, you can specify the location of the drawn string. this example we will draw two string "Hello", "Word" ("Hello" in blue color upfront "Word" in red color):

string firstText = "Hello";
string secondText = "World";

PointF firstLocation = new PointF(10f, 10f);
PointF secondLocation = new PointF(10f, 50f);

string imageFilePath = @"path\picture.bmp"
Bitmap bitmap = (Bitmap)Image.FromFile(imageFilePath);//load the image file

using(Graphics graphics = Graphics.FromImage(bitmap))
{
    using (Font arialFont =  new Font("Arial", 10))
    {
        graphics.DrawString(firstText, arialFont, Brushes.Blue, firstLocation);
        graphics.DrawString(secondText, arialFont, Brushes.Red, secondLocation);
    }
}

bitmap.Save(imageFilePath);//save the image file

编辑：我添加的加载和保存code

"I Add a load and save code".

您可以打开该位图文件的任何时间 Image.FromFile ，并绘制使用上述code上有一个新的文本。然后保存图像文件 bitmap.Save

You can open the bitmap file any time Image.FromFile, and draw a new text on it using the above code. and then save the image file bitmap.Save
