How to analyze the image url in json?

Hello

I get the response from the server and crawled through json. And display it in the field

Like name1 as:

try {}
labelField1.setText (jsonObject2.get("name1").toString ());
}

catch (JSONException e)

{
System.out.println ("JSONException Description");
}

Similarly, I want to make the image. How to analyze the url of the image and display it in the BitmapField?

You must create a separate thread to extract the bytes of the image of the URL you have.

You can use the following code to get the image to the server.

public EncodedImage getImageBytesFromURL(String url){
        ConnectionFactory connFactory = null;
        ConnectionDescriptor connDescriptor = null;
        HttpConnection httpConn = null;
        InputStream inputStream = null;
        byte[] response = null;
        try {
            connFactory = new ConnectionFactory();
            connFactory.setConnectionTimeout(10*1000);
            connFactory.setAttemptsLimit(1);
            connDescriptor = connFactory.getConnection(url;interface=wifi);
            if (connDescriptor != null) {
                httpConn = (HttpConnection) connDescriptor.getConnection();
                inputStream = httpConn.openInputStream();
                int responseCode = httpConn.getResponseCode();
                if(responseCode == HttpConnection.HTTP_OK){
                    response = readStream(inputStream);
                }
            }
        }catch (IOException e) {

        }finally {
            try {
                inputStream.close();
                httpConn.close();
                inputStream = null;
                httpConn = null;
                connDescriptor = null;
                connFactory = null;
            } catch (Exception e) {

            }
        }
        EncodedImage encodedImage = null;
        if(response != null){
            encodedImage = EncodedImage.createEncodedImage(response, 0, response.length);
        }
        return encodedImage;
    }

Remember that this method should be in a background thread. Otherwise, your user interface crashes. The encodedImage that returns the method above can be easily converted to bitmap and set in your bitmapfield.

  • How to change the Image the Image (8 bit) (32 bit)?

    Dear all,

    I have a question about VISION.

    An Image from IMAQ USB Grab Acquire.vi is 32-bit, even if the IMAQ Creat.vi has the type U8 value.
    But the more IMAQ vi (for example IMAQ get LCD ROI.vi) can only deal with 8-bit Image.
    How to change the Image from 32-bit to 8-bit Image?
    Thank you!

    Hugo

    Hi Hugo,.

    You use a color camera? coz usually 32 bit for a color image.

    If so, you can try the unique color Pane.vi extract to extract its Luminance component. It then becomes an 8-bit grayscale image.

    I had to help someone with something similar to this:

    You can add an extra function so that she gets the EncodedImage and returns.

    In fact, I just realized that EncodedImage.getEncodedImageResource has support for the specification of the module that contains the resource.

    Hai, I am very new in the development of blackberry applications. I need an image that need to be done rotate 360 degrees once only. I see so many references here and I know that there is a thread that discuss it, but I can't find the right one.

    Thanks in advance.

    You asked a single rotation - "how to rotate the image only once.

    There is no standard API that provides a rotating image permanently using standard features of BlackBerry.

    The usual way to display animations is demonstrated in this article.

    If you can prepare your animation and package with your application, it will be much easier and more effective. Do you know what pictures you're going to turn?

    How to change the image field captures screenshots automatically from BMP to JPEG

    I want to say, when I tap on the screenshot on my keyboard and paste this image in microsoft photo editor or picasa 3.0 areas of the bitmap .bmp. instead of asking the witch I´d field prefer.
    So, I open that image on the brush to convert it to. JPEG.
    It's hick very!
    is it possible to easily me this step and save or paste pictures in JPEG on my files automatically?

    Hello

    I saw that article when I was looking for one that I posted...

    I understand your problem, and the answer is that, to the best of my knowledge... NO..

    Windows records the capture in memory as bitmap, along with, even if you can paste it directly into a folder, it would be in the form of bitmap...

    The best I could find is to use the suggestion in the link I've included which refers to the

    Windows Key + PrintScreen to automatically record is in PNG format in your pictures folder...

    The only way to do what you want is with a 3rd party capture program that can be configured to save in a directory as a specific file type...

    Personally, I use a program called print screen Deluxe for this... it is a purchased program...

    I'm sure you could find something free to do what you need...

    You may need to use a different key for print screen, but the software can allow you to reprogram the PrntScrn key...
