Troubleshooting JPEG

[MarcFletcher]

I have another problematic JPEG, although I assume a different problem to the one I reported in issue #22:

I am unable to load the following JPEG, source : http://static.lexpress.fr/medias_9804/w_1970,h_1478,c_crop,x_0,y_0/w_605,h_350,c_fill,g_north/v1409117471/un-nouveau-record-du-chomage-en-france-comme-cadeau-de-bienvenue-manuel-valls-a-prevenu-des-mardi-que-les-chiffres-de-juillet-que-pole-emploi-devoile-mercredi-au-lendemain-de-la-nomination-du-nouveau-gouvernement-ne-seraient-pas-bons_5019824.jpg

Code snippet:

URL url = new URL(imageURLStr);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
//image is null, i.e. read failed
BufferedImage image = ImageIO.read(conn.getInputStream());

I have both the following dependencies confirmed as loaded:

        <dependency>
            <groupId>com.twelvemonkeys.imageio</groupId>
            <artifactId>imageio-jpeg</artifactId>
            <version>3.1.1</version>
        </dependency>
        <dependency>
            <groupId>com.twelvemonkeys.imageio</groupId>
            <artifactId>imageio-tiff</artifactId>
            <version>3.1.1</version>
        </dependency>

I have several example of images from the same website that suffer from this problem. Any help with this type of image would be greatly appreciated.

Hi,

Thanks for reporting!

However, I just downloaded your linked image, and it reads just fine using code similar to your snippet.

public static void main(String[] args) throws IOException {
    URL url = new URL(args[0]);
    HttpURLConnection conn = (HttpURLConnection) url.openConnection();
    //image is null, i.e. read failed
    BufferedImage image = ImageIO.read(conn.getInputStream());
    System.err.println("image: " + image);
    JPEGImageReader.showIt(image, "image"); // NON-API, just to show the contents looks good
}

Best regards,

Harald K

How annoying ;) After doing some further digging it looks like i was getting the image from a CDN node (where the image was corrupted). If I used a VPN endpoint in a different country the above worked ok.

Many kind thanks for the v.quick response and apologies that I didn't think of trying this before posting.

Ok!

No problem!
