Use Gogole map static api

Programming Questions

Hello

I'd like to include a Google Map onto my Processing process. I wonder if anybody had this experience. In fact, I don't need dynamic map, so just static api would be fine.

I can get the image as a extention-less URL string, but didn't really work with PImage. And I also tried "Toolkit." but it says:
Cannot find anything named "Toolkit"

byte[] b = loadBytes("http://maps.google.com/maps/api/staticmap?center=Berkeley,CA&zoom=14&size=400x400&sensor=false");
Image javaImage = Toolkit.createImage(b);
PImage aaa = new PImage(javaImage);

Does anyone know how I can call the static map image ?? Thanks a lot!

try:

aaa = loadImage(yourexistingurl,"jpg")

or append something like "&junk=.jpg" to the end of your url like so:

aaa = loadImage(yourexistingurl+"&junk=.jpg");

and done. processing's image loader looks for recognized extensions to determine which "loader" to invoke, so just give it that "clue", and the google api should ignore it. (you may just want to make sure your extension matches google's default &format= or manually specify that format, if you get garbage results from decoding as the wrong format) (alternatively, use getToolkit() in place of just Toolkit)

Thanks for your reply. But your suggestions didn't work for me.

1. Using loadImage:

PImage img;
void setup() {
size(400,400);
img = loadImage("http://maps.google.com/maps/api/staticmap?center=Berkeley,CA&zoom=14&size=400x400&sensor=false","&junk=.jpg");
image(img,0,0,width,height);
}

The error message:
Could not find a method to load http://maps.google.com/maps/api/staticmap?center=Berkeley,CA&zoom=14&size=400x400&sensor=false
Then, "NullPointerException"

2. I also tried:

byte[] b = loadBytes("http://maps.google.com/maps/api/staticmap?center=Berkeley,CA&zoom=14&size=400x400&sensor=false");
Image javaImage = getToolkit.createImage(b);
PImage aaa = new PImage(javaImage);

It still says:
Cannot find anything named "getToolKit"

Should I include some more codes before the code? Things like "insert package?"

Thanks a lot!

re-read prior reply a little more carefully, you've almost got it:

if you're using the two parameter version of loadImage(), the first param is your existing url, the second parameter will be JUST "jpg"

if you use the one parameter version of loadImage(), that's when you'd append "&junk=.jpg" to your existing url

if you want to use getToolkit() you have to include the parenthesis (tho i'd recommend one of the loadImage() approaches)

This works for me:

PImage img;
void setup() {
size(400,400);
img = loadImage("http://maps.google.com/maps/api/staticmap?center=Berkeley,CA&zoom=14&size=400x400&sensor=false","jpg");
image(img,0,0,width,height);
}

EDIT: oops, didn't notice davbol replied already...

Thanks to everyone.
Your tips worked for me. First I tried on my work computer, which I think have some security blocking...so it didn't work. But it works perfectly on my laptop at home. :-)
