save image files in C#

Question

How can we save image files (types such as jpg or png) in C#?

Answer 1

in c# us the Image.Save Method with these parameters (string Filename , ImageFormat)

Is that all you needed?

// Construct a bitmap from the button image resource.
Bitmap bmp1 = new Bitmap(typeof(Button), "Button.bmp");

// Save the image as a GIF.
bmp1.Save("c:\\button.gif", System.Drawing.Imaging.ImageFormat.Gif);

Answer 2

Image bitmap = Image.FromFile("C:\\MyFile.bmp");
bitmap.Save("C:\\MyFile2.bmp");  

You should be able to use the Save Method from the Image Class and be just fine as shown above. The Save Method has 5 different options or overloads...

  //Saves this Image  to the specified file or stream.
  img.Save(filePath);

  //Saves this image to the specified stream in the specified format.
  img.Save(Stream, ImageFormat);

  //Saves this Image to the specified file in the specified format.
  img.Save(String, ImageFormat);

  //Saves this image to the specified stream, with the specified encoder and image encoder parameters.
  img.Save(Stream, ImageCodecInfo, EncoderParameters);

  //Saves this Image to the specified file, with the specified encoder and image-encoder parameters.
  img.Save(String, ImageCodecInfo, EncoderParameters);

If you need more extensive image handling than the .Net Framework provides out of the box, check out the FreeImage project
