将图像保存到文件 [英] Saving image to file

问题描述

我正在开发一个基本的绘图应用程序.我希望用户能够保存图像的内容.

I am working on a basic drawing application. I want the user to be able to save the contents of the image.

我认为我应该使用

System.Drawing.Drawing2D.GraphicsState img = drawRegion.CreateGraphics().Save();

但这并不能帮助我保存到文件.

but this does not help me for saving to file.

推荐答案

您可以尝试使用这种方法保存图像

You could try to save the image using this approach

SaveFileDialog dialog=new SaveFileDialog();
if (dialog.ShowDialog()==DialogResult.OK)
{
   int width = Convert.ToInt32(drawImage.Width); 
   int height = Convert.ToInt32(drawImage.Height); 
   Bitmap bmp = new Bitmap(width, height);        
   drawImage.DrawToBitmap(bmp, new Rectangle(0, 0, width, height));
   bmp.Save(dialog.FileName, ImageFormat.Jpeg);
}
