Saving images

You have already learned how to load and download images, so now it's time to learn how to save your image. We will use the save function from the Images package to save the image to disk.

The save function accepts two arguments:

• The destination file location and name
• The image object

Let's have a look at the code to save images: 

  # load an image
  img = load("sample-images/cats-3061372_640.jpg")

  # save file in JPG format
  save("my_new_file.jpg", img)

  # save file in PNG format
  save("my_new_file.png", img)

The image format is chosen based on the filename extension. Please note that saving the image in different formats can affect the output quality and file size. Users should find a balance between size and quality.

The save function does not allow you to set image quality, which is usually available in graphics editors, such as GIMP.
