How can I cast or initialize an ImageInputStream with an InputStream?

Question

I am developing an image cleaning application. I get the url

URL imageUrl = new URL(imageSource); 

Then I create an InputStream with this URL:

 InputStream is = new URL(imageUrl.toString()).openStream(); 

After that, I want to create an ImageInputStream to define ImageIO readers.

 ImageInputStream iis = ?????? 

But I could not initialize this. Can I implement a URL or InputStream for ImageInputStream?

Answer 1

this is what you are looking for:

 ImageInputStream iis = ImageIO.createImageInputStream(is); 

Answer 2

Best to use ImageIO.read(url) which returns BufferedReader
