grandma is happy now that i've integrated the weather module on her TSU9400. has anyone created a prontoscript to download a jpeg of a weather radar image?

I haven't done exactly that, but downloading an image is pretty simple. You have the sample code in the developers giude. It's just a matter of fine tuning to get it to work.

I'm not sure if I'm allowed to link directly to the document, but you can find it if you have an account and log into the following site: [Link: pronto.philips.com]

Thanks for the reply, though registered i'm not certified and therefore cannot access that area. Would someone please paste the sample code?

The developers guid is featured in this sites file area, try there.

In this thread is an example:
[Link: remotecentral.com]

here's my script to retrieve a radar image. the location of the file is:

could someone take a look to see if there's anything i'm doing wrong:

var socket = new TCPSocket();
var receivedData = "";
socket.onConnect = function() {
write("GET /data/nids/IND19_thumb_t.jpg” + " HTTP/1.0\r\n\r\n");
};
socket.onData = function() {
receivedData += read();
};
socket.onIOError = function (e) {
widget(“output”).label = "IOError " + e;
};
socket.onClose = function () {
// remove the HTTP information from the received data
var imageStartIndex = receivedData.indexOf("\r\n\r\n");
var bitmapData = receivedData.substring(imageStartIndex+4);
// make and display the image
var MyImage = new Image(bitmapData);
widget(“output”).setImage(MyImage);
};
socket.connect('icons.wunderground.com',80,3000);

Start of by replacing/re-entering all the cuotation marks. In some places you are using ' in some others " and yet also in some places ”. You should use either " or '.

Then I don't know if you have a widget called output (if I remember correctly this is the default widget name in the developers guide). If you don't, then just create it, or rename the output widget in the code to whatever your widget is called in your setup.

That shold be all you need to do... I think! ;)

Btw, I just came up with a related question on my own that maybe some of the more advanced developers at this site might know the answer to.
When you open a socket as in the example mentioned above. Will the socket close by itself if there is an IOError or do I have to close it manually?

Krazz,

An HTTP server will close the connection after it has transmitted all the content in response to an HTTP request, unless the request contains "Connection: Keep-Alive" header or is an HTTP/1.1 request without a "Connection: close" header.

However, not all TCP socket communication is with HTTP servers. If the server doesn't close connections automatically (as with HTTP), the client should close them.

You may find that you also need to add a "Host" request header and specify:

icons.wunderground.com

as the value.


Krazz, on an IO Error, the socket is typically closed for you but as good programming practice, you really should examine the "connected" flag and issue a close() in try/catch block if not closed upon receipt of IO Error. This way, should the underlying functionality ever change, your code still behaves correctly.

Lyndel McGee: That makes sense to me. Thank you.

Lyndel is 99% correct and I should clarify the solution. An internet image's address, i.e., ww3.weather.com/images/.....jpg is not the true location of the file. On the HTTP server, the www, or any other folders location can be set to be anywhere within that computer. The script does work. Thanks to everyone for the help. Now, if i could get get the stretch function to work.

How in the heck am I 99% correct? I only suggested he add the Host request parameter. I said nothing about the actual file location?

I'm totally confused here. Help me out.

Stretch works fine. Before assigning the image to a panel/button, simply specify w.stretchImage = true;

Trying to load images from remote web server, noticed delays between closing the socket, and low frame data size per query.My image is for about 30kbytes size but it uses 6 frames for image loading, what is going wrong?

var socket = new TCPSocket();
var receivedData = "";
var MyImage;
socket.connect("192.168.0.2",80,100);
socket.onConnect = function()
{
System.print("connected");
socket.write("GET /poo.jpg HTTP/1.1\r\n");
socket.write("HOST: 192.168.0.2\r\n\r\n");
System.print("write");
};
socket.onData = function()
{
receivedData += socket.read();
System.print ("TCP DATA RECEIVED:"+ receivedData);
var imageStartIndex = receivedData.indexOf("\r\n\r\n");
var bitmapData = receivedData.substring(imageStartIndex+4);
// make and display the image
MyImage = new Image(bitmapData);
};
socket.onIOError = function (e)
{
GUI.widget("panl").label = "IOError " + e;
};
socket.onClose = function () {
System.print("closed");
};
GUI.widget("panl").stretchImage=true;
GUI.widget("panl").setImage(MyImage);

I've tried to close manually(adding socket.close(); at the end of onData function), but in that case it didn't reach the onData block at all.

It closes sockets manualy after 3 min delays

Likely nothing you can do on webserver end. Some webservers send 'chunked' data. If you have access to Philips RSS reader, there's a function there to 'unchunk' the data but I doubt that is your real issue (until you can fix your code and prove me wrong).

Things you must do:

If you did not know this, please take it in stride...
Script is executed from top to bottom in the order the statements are defined.

Note that you are calling socket.connect() on the socket before defining an onConnect callback function or any other functions for that matter. You must move the socket.connect() call to the end of your script and things will likely work more like what you expect as you will have "hooked" all the callbacks on the socket at that time.

Things I strongly recommend:

To ensure that you can handle multiple packets of data you should:
1) Use HTTP 1.0 instead of 1.1 in your request.
2) And move your image loading from onData() function into to onClose().
3) Investigate the 'chunking' but I doubt that is really the issue here.

Thanks for help! After changing to HTTP 1.0 and pasting the image creation snippet into onClose block all works fine, chunking dissapeared(may be Solaris webserver configuration changed))). It seems like 1 pic loaded for about 1 second(30-70kbytes), but how i can get 12 or more pics per second if i would work with IP camera?Or there's another factors make sense?
