I am trying to download the following image over IP:



...using the following code (closely based on the example on p45/46 of v1.1 of the ProntoScript dev guide):

--------------------------------------------------------------
var socket = new TCPSocket();
var receivedData = "";

socket.onConnect = function() {
socket.write("GET /uploadtop/v/visual_nustraks.jpg" + " HTTP/1.1\r\n\r\n");
};

socket.onData = function() {
receivedData += socket.read();
};

socket.onIOError = function (e) {
CF.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);
CF.widget("output").setImage(MyImage);

};

// MAIN
socket.connect('static.tvgids.nl', 80, 6000);

--------------------------------------------------------------

I don't get any picture displayed in my "output" panel !?
Any suggestions (or working example to start with...) ?

Try changing this line:
socket.write("GET /uploadtop/v/visual_nustraks.jpg" + " HTTP/1.1\r\n\r\n");

to this:
socket.write("GET /uploadtop/v/visual_nustraks.jpg" + " HTTP/1.0\r\n\r\n");

And if that does not work, it may be that the image data is 'chunked'. There's a function to "unchunk", per se in the Philips RSS example on the Pronto Website. You must be level-1 certified to be able to download this, I believe.

APIERRE got it.
Try to make use of debug panels (ProntoScript name _PS_DEBUG_).
Barry has posted a TSU9600 debug mod. Have a look and try it as it is a great feature.
Make sure that your 'panel' has its ProntoScript name sat as: panel

This should get you started:

var socket = new TCPSocket();
var receivedData = "";

socket.onConnect = function() {
System.print ("TCP connected");
socket.write("GET /uploadtop/v/visual_nustraks.jpg" + " HTTP/1.0\r\n\r\n");
//socket.write("GET /uploadtop/v/visual_nustraks.jpg" + " HTTP/1.1\r\n\r\n");
};

socket.onData = function() {
receivedData += socket.read();
System.print ("TCP DATA RECEIVED:"+ receivedData);
};

socket.onIOError = function (e) {
GUI.widget("panel").label = "IOError " + e;
System.print ("TCP ERROR:"+ 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);
GUI.widget("panel").setImage(MyImage);


};

// MAIN
socket.connect('static.tvgids.nl', 80, 6000);

Be aware that if you are attempting to fetch images from Escient Fireball PC on port 7445, the software does not honor HTTP 1.0 close and relies on the client (your TSU9600) to close the socket so with Escient Fireball PC. Therefore, the above examples will not work.

This was a real pain with my Escient Integration because with each block of data received, I had to analyze all the data to see if I had all expected content.

Thx guys, as I have had problems in the past with HTTP /1.0 I used HTTP 1.1 instead. In this case changing it back to 1.0 did the job but I still don't get 10 out of 10 pages succesfully returned.
Another issue is than when use 1.0 and when use 1.1 (or is it just a case of testing what works for each specific HTML page) ?

Just out of curiosity, why would you want to grab that picture? It does not show the current channels its just a background picture. You can better just put it in your gallery..

I did some simple scaling tests today (setting stretchimage to true and false) and it seems pretty fast. I haven't done any resolution tests to see how well the scaling to widgets filters, but it should be fine for what it is.

Snelvuur, just a picture I found on that website to try a picture download enabled by the new firmware on.....
My question on when to use 1.0 or 1.1 still remains unanswered.
Btw, anyone else that has experience with downloads of the same webpage failing every now an then ?
