getting image from Flickr to display in Processing
Sep 3rd, 2006, 2:48am  
Hi,

I would like to get images from Flickr
(based on one or more tags, like "red", "woman", "face")
and display the images in Processing.

I have looked at the "switchboard" library,
but there doesn't seem to be real Flickr support,
and the few things I found by googling around
seemed remarkably complex, ... presumably to parse
the responses received from Flickr.com

Can anyone point me to a working example in Processing
to get and display a bunch of images from Flickr?

I'm looking into getting real Flickr support for Processing. In the mean time, check out http://www.tom-carden.co.uk/p5/flickr_rainbow_links_fixed/applet/index.html

There's a Java wrapper for the Flickr API, but it seems to be broken. (If anyone knows how to use the Flickrj Flickr API, please tell.)

I get the impression that Flickrj may be dead Sad.
The last updates on the Flickj web page were over a year ago,
and that was for version 1.0a9, ... and it was still "alpha".
http://sourceforge.net/projects/flickrj/

The Flickr API page ( http://www.flickr.com/services/api/ )
seems to indicate a potentially easy interface using HTTP GET/POST
using a request format they call "REST" (http://www.flickr.com/services/api/request.rest.html).

It would still require pulling apart the XML response it sends back, but that might be manageable after inspecting a few typical responses.

The "method" that I would be interested in using to download images would be "flickr.photos.search" (http://www.flickr.com/services/api/flickr.photos.search.html).

Has anyone used this to download images into a Processing applet?
Any tips or examples would be appreciated.

Hey,

I'd love to do some work pulling pictures from Flickr, but I'm not sure where to start. Has anyone got anywhere with this lately?

Well... I do a ton of stuff with pulling from the Flickr API every day. Is there anything specific you would like to know?

I do have my own library for handling the Flickr API but it's nowhere near ready for a release.

Pulling an image is pretty straightforward. First you need to get a list of images from photos.search method. Then when you obtain information about images, I have this method that you can use that might help you out:

Code:

static final String FLICKRurlPrefix = "http://farm";
static final String FLICKRurlSuffix = ".static.flickr.com/";
static final String backslash = "/";
static final String underscore = "_";
static final String FLICKRimageFormat = ".jpg";

final static String getFlickrImageURL(String farmID, String serverID, String id, String secret, char format){
//flickr url format
//  http://farm{farm-id}.static.flickr.com/{server-id}/{id}_{secret}.jpg

StringBuffer url = new StringBuffer();

url.append(FLICKRurlPrefix);
url.append(farmID);
url.append(FLICKRurlSuffix);
url.append(serverID);
url.append(backslash);
url.append(id);
url.append(underscore);
url.append(secret);
url.append(underscore);
url.append(format);
url.append(FLICKRimageFormat);

return url.toString();
}


That gives you the direct URL to any flickr image you want so you can retrieve it via loadImage().


Here's an excerpt from my FlickrPhoto object constructor

Code:

	public FlickrPhoto(XMLElement photo){
		try{
			this.id = photo.getAttribute("id");
			this.owner = photo.getAttribute("owner");
			this.secret = photo.getAttribute("secret");    
			this.server = photo.getAttribute("server");    
			this.farm = photo.getAttribute("farm");    
			this.title = photo.getAttribute("title");
			if(photo.hasAttribute("tags"))
				this.tags = PApplet.split( photo.getAttribute("tags"),  " " );			
			if(photo.hasAttribute("datetaken")){
				this.dateTaken = photo.getAttribute("datetaken");
			}

			this.imageURL = FlickrAccess.getFlickrImageURL( farm, server, id, secret, 'm');
			load();
			
//			NetQueue.executeLoad(NetMethod.call(this,"mLoadImage"));			
		}
		catch(Exception e){
			PApplet.println(e);
			noError = false;
		}
	}



Basically you pass it the xml leaf for the photo, and it converts it into a PImage you can then play with.



Then you can wrap the whole thing up in its own thread for smooth loading.

as stated earlier flickr pics are simply URLs,
If you know these, its simpler...

Isn't it not much easier to use the flickrj API (http://flickrj.sourceforge.net/), which wraps all the REST stuff in an easy to use JAVA. I've used it in the last weeks to experiments with contacts data and it was much easier as the stuff I done two years ago as I parse the whole xml myself.

Possibly easier yes but learning how to do it on our own stems from partly ignorance for other libraries, and a stubborn refusal to use other people's code.

Sadly!

Hey,

I have successfully done this before using the p5 core code and code from here:
http://wiki.netbeans.info/wiki/view/NBDemoFlickr

Specifically the Flicker.java class
You need a Flickr API Key, and the code reads the XML returned from a search query.

I adapted the class to return an Image instead of an Icon, and also inserted a page offset variable into the search query.
In the end it looked like this:

Quote:


public PImage randomImage() {
 String pageOffset = String.valueOf((int)root.random(1.0F, 100F));
 java.awt.Image random = Flickr.getInstance().search("words to search for", pageOffset);
 if(random != null){
   PImage randomP = root.loadImageSync(random);
   return randomP;
 } else {
   return null;
 }
}

I did it in Processing by HTTP call and parsing of XML return string. Have a look at

http://www.bryanchung.net/index.php/?p=189

and related posts.

eskimoblood,
I tried to use it in order to get contacts data too... but still doesn't work !
could you help me I guess it is an auth problem...

If you use it from processing IDE it doesn't shows you that you have to catch some exceptions that Flickr class throws:

Code:


import java.io.IOException;
import processing.core.*;
import org.xml.sax.SAXException;
import com.aetrion.flickr.*;
import com.aetrion.flickr.contacts.*;
import com.aetrion.flickr.people.*;
import com.aetrion.flickr.FlickrException;


String apiKey = "yourKey";
Flickr f;
ContactsInterface c;
PeopleInterface p;

void setup()  {
size(500, 500);
f= new Flickr(apiKey);
c=f.getContactsInterface();
p=f.getPeopleInterface();
User u;
try {
u = p.findByUsername("eskimoblood");
Collection co= c.getPublicList(u.getId());
Iterator it=co.iterator();
while(it.hasNext()){
Contact contact=(Contact) it.next();
println(contact.getUsername());
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SAXException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (FlickrException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

Within eclipse its much easier, cause it have auto suggest to solve your problems, so that a dummy like me can handle that stuff.

Hi eskimoblood-
Thanks for posting this code...very useful.  Unfortunately, I am getting an error:

com.aetrion.flickr.FlickrException: 96: Invalid signature

I have tried a bunch of different code snippets (including those of Daniel Shiffman (http://www.shiffman.net/teaching/a2z/mining/), made sure my flickr apikey is correct etc and am still getting this error.  Any thoughts or suggestions would be fantastic.
Thanks!
