Hey everyone,

I really need some help with this issue I cannot get rid of! I am trying to make an app that loads an image saved on the BB device and that sends it to a server, the problem is that we can only send a byte[].

So i am trying to implement the following method:

- Load the image via the FileConnection class

- Open an InputStream of the said FileConnection

- Convert that InputStream to a byte array

The code should look like this I guess:

FileConnection file = (FileConnection)Connector.open("Original_SealV.jpg");
InputStream is=file.openInputStream();

byte[] img=null;
int temp=is.read();
while(temp>0){

// Convert to byte here?

}

It is the last step which I am lacking, i have tried several methods but could not get it to work, thus i am imploring for a little bit of the vast collective wisdom of these forums...

Could anyone help me? I won't forget the kudos!

U can try this.

int len=(int)hc.getLength();

byte bts[]=new byte[len];

It converts into bytes.

Sorry hc is the HttpConnecion Object.

Thanks for the quick reply, but the problem is actually the other way around: I am trying to load an image on the Blackberry and then upload it, but prior to uploading I need to convert this image to a byte[].

If I misunderstood your answer, could you explain a bit more?

U r reading Image from Real Device Not from web.

So same Procedure r there to Convert Image in the Bytes Array.

Like U r Using code for reading Image form Web.

Same Procedure should be USed from real device.

This is not the Other things.

Okay, could you give me the full code or just state the algorythm then? I cannot do a .getLength() on my FileConnection, and I don't really understand your solution either, in fact.

[Benjen]

I have tried doing something like this, is that what you meant?

InputStream is=file.openInputStream();
int len=(int)file.fileSize();
byte[]img=null;
is.read(img,0,len);

Any other participation would be welcomed!

My Mean is this

                hc=(HttpConnection)Connector.open(url);
                hc.setRequestMethod(HttpConnection.GET);
                int len=(int)hc.getLength();
                byte bts[]=new byte[len];

Now the Image in the bts in Byts Format.

[Plato · Accepted solution]

or you can always use the standard API

byte[] buf = IOUtilities.streamToBytes(stream);

[Benjen]

Perfect, exactly what I needed, it makes my question kind of dumb in fact.

Thanks a lot Plato!
