I am developing an image scraping application. I am getting URL
URL imageUrl = new URL(imageSource);
Then I'm creating an InputStream with this URL:
InputStream is = new URL(imageUrl.toString()).openStream();
After this I wanna create an ImageInputStream to determine ImageIO readers.
ImageInputStream iis = ??????
But I couldn't initialize this. Can I implement URL or InputStream for ImageInputStream?
this is what you are looking for:
ImageInputStream iis = ImageIO.createImageInputStream(is);
Better way is to use ImageIO.read(url)
that returns BufferedReader
URL imageUrl = new URL(imageSource);
InputStream is = new URL(imageUrl.toString()).openStream();
ImageInputStream iis = ImageIO.createImageInputStream(is);
Iterator<ImageReader> iter = ImageIO.getImageReaders(iis);
if(!iter.hasNext())
throw new RuntimeException("No readers found");
ImageReader reader = iter.next();
This is how you get your reader, or one of the ways of getting the reader. Hope it helps.
