我想在.NET 4.0中编写一个小程序,它将打开一个.jpg(或.jpeg)文件,在图像上添加一行文本,然后将图像重新保存为.jpg.有谁知道最简单的方法吗?
谢谢你的帮助.
像这样的东西:
var filePath = @"D:\Pictures\Backgrounds\abc.jpg"; Bitmap bitmap = null; // Create from a stream so we don't keep a lock on the file. using (var stream = File.OpenRead(filePath)) { bitmap = (Bitmap)Bitmap.FromStream(stream); } using (bitmap) using (var graphics = Graphics.FromImage(bitmap)) using (var font = new Font("Arial", 20, FontStyle.Regular)) { // Do what you want using the Graphics object here. graphics.DrawString("Hello World!", font, Brushes.Red, 0, 0); // Important part! bitmap.Save(filePath); }
