I have a facebook app, with an page whith its meta og tags. When I run http://graph.facebook.com/ID_Object, I get a json file with no entry for share-count but the page was shared several times. How to do that ?
Try calling the url by id.
https://graph.facebook.com/?id=YourURL
refer to: https://developers.facebook.com/docs/reference/api/#auth
You can also request multiple objects in a single query using the
"ids" query parameter. For example, the URL
https://graph.facebook.com?ids=arjun,vernal returns both profiles in
the same response.
The "ids" query parameter also accepts URLs. This is useful for
finding IDs of URLs in the Open Graph. For example:
https://graph.facebook.com/?ids=http://www.imdb.com/title/tt0117500/
The Open Graph protocol defines four required properties:
og:title - The title of your object as it should appear within the graph, e.g., "The Rock".
og:type - The type of your object, e.g., "movie". See the complete list of supported types.
og:image - An image URL which should represent your object within the graph. The image must be at least 50px by 50px (though minimum 200px by 200px is preferred) and have a maximum aspect ratio of 3:1. We support PNG, JPEG and GIF formats. You may include multiple og:image tags to associate multiple images with your page.
og:url - The canonical URL of your object that will be used as its permanent ID in the graph, e.g., http://www.imdb.com/title/tt0117500/.

I'd like to ask if there is any way to get thumbnail image for media returned from Instagram Graph API? I can get an image URL by using following endpoint: /{InstagramUserId}/media?fields=media_url
However it only returns one size. Old Instagram API returned various sizes like low_resolution, thumbnail, standard_size. Is it possible to get similar result by using Instagram Grahp API?
After searching for some time to a solution i finally found one.
So, include in the fields query string the permalink field and it should give as following (Sorry, for using Kim Kardashian as an example):
https://www.instagram.com/p/CAYDz52gSLh
then append this at the end media?size=t or simply media like this:
https://www.instagram.com/p/CAYDz52gSLh/media?size=t
media?size=t will give a 150x150 px image
media?size=m will give a 320x320 px image
media?size=l will give a 1080x1080 px image
I can not find a way to get the thumbnails in one step.
But in the next step after receiving the data, the thumbnail of each image and video can be found in this way using oEmbed:
https://graph.facebook.com/v9.0/instagram_oembed?url={permalink}&maxwidth=320&fields=thumbnail_url,author_name,provider_name,provider_url&access_token={accessToken}
permalink: The url received from the previous stage (business_discovery)
Example:
https://graph.facebook.com/v9.0/instagram_oembed?url=https://www.instagram.com/p/CBOuPY1AcMQ/&maxwidth=320&fields=thumbnail_url,author_name,provider_name,provider_url&access_token={accessToken}

I can insert the tags on the image. The problem is that every tag that i insert stays with the name "PrivateTag" on LeadTools or the number of the tag on AsTiffTagViewer. Only the name of the tag.
I'm following the example of this guy:
Adding custom tags to a TIFF file
The code is not so different.
Thanks for the help.
TIFF spec states that tags 32768 or higher are "private tags", which means their names vary widely from one organization to another. If the TIFF viewer is not from the same organization that wrote the tag, it will ignore it. Your code defines the tags starting with 65000, which is in the private range. If you're using the LEADTOOLS Tag Editor, it has no way of knowing what you mean by them. If you want a viewer to assign specific names to these tags, write your own TIFF viewer or tag editor. One way to do that is to use the LEADTOOLS imaging SDK.
I've created a new page Aikau, but I changed the XML file and the rendered page content between the standard Share header and footer disappeared.
In this page, I want the arguments of the query string, so I write this code:
page.get.desc.xml:
<webscript>
<shortname>My New Page</shortname>
<url>/hdp/ws/my-new-page</url>
<authentication>user</authentication>
</webscript>
page.get.js:
function main ()
{
// Get the args
var fileProp = args["test"];
model.temp = fileProp;
}
main();
page.get.html.ftl:
Test arg: ${temp}
I have to put /hdp/ws/my-new-page in the XML file to write the content of FTL file in this page... But why did the header and footer of the Alfresco template disappeared ? hdp serves for this purpose. And if I don't put the URL like that on the XML, the page appears with the template.
What is wrong in my code? Or how can I recover the template? Or add header and footer?
EDIT: I already try to put only /my-new-page without /hdp/ws/ but the args are null when I put /hdp/ws/. Give me a hint.
EDIT2: I already try to import alfresco-template.ftl but I can't. Any idea?
You don't actually need to include the the "hdp/ws" part in your WebScript descriptor. Only the "/my-new-page" is required. Aikau attempts to simplify the Surf page creation by providing a number of pages out-of-the-box (and the "hdp" page is just one of them).
Aikau uses URI-template mapping to match a single WebScript to a page, so for example in the URL:
/share/page/hdp/ws/my-new-page
share = application context
page = Spring MVC request dispatcher
hdp/ws/my-new-page is then mapped to the URI template:
<uri-template id="share-page">/{pageid}/ws/{webscript}</uri-template>
Where "hdp" is the id of the page to render and "my-new-page" is the WebScript URL. The HDP page uses the "webscript" token from the template to automatically create a new Surf Component and bind it to the WebScript.
But in short - don't include "hdp/ws" in your WebScript URLs for Aikau pages.
You need to make the things that you have on javascript server in this javascript mandatorily? If not, you can create a javascript client that receive the same arguments (location.search give to you the query string, so, you can make parse of that query string and get only the value of the "test" that you want) and call them on FTL file (the client-side javascript). So, when the page loading, it does not lose the arguments. It isn't the best solution but you can try this...
How do I fetch Page Name with Yahoo Pipes?
I'm making a news / blog aggregator, and need to know the name of the site where the info is coming from (bbc, cnn, fox, etc).
Do I need to do this with REGEX?
Anyone that can help?
You can fetch the page using the XPath Fetch Page or Fetch Feed modules in the Sources menu. Maybe with others too.
After that you can extract the page name itself using the various operators, possibly Regex, or others, depending on the source page you are using and the output you want to get.
In general your question is too broad and difficult to answer. To get you started, I created an example pipe that extracts the title of your question from this post, which is basically the "page name" of the current page.
http://pipes.yahoo.com/pipes/pipe.info?_id=668acf3f807c30d7b75f12459edd3252
I used the XPath Fetch Page with parameters:
URL = this page
Extract using XPath = //div[#id="question-header"]
I got that div path by inspecting the source code of this page, where I saw that div#question-header is the container of a question. I could have selected a deeper inner container or a higher level container. It all depends on the amount of other information you need. The more information you want to you from the page, the higher level container you select.
Next, I used the Create RSS operator to create a proper RSS feed, with parameters:
Title = h1.a
Link = h1.a.href
I chose these elements because in the container I extracted with xpath, the page name is inside h1 a. In Yahoo Pipes you use a dot as the path separator.
I found this sample pipe http://pipes.yahoo.com/pipes/pipe.info?_id=69b5dce1c59501a0c64a660c1cfdb856. The page title included the name of the site too. I am not sure if this what you are looking for.
I am doing a monitoring system using Django. In my views file, I have defined one class called showImage which collects the information necessary to plot a graph using matplotlib.
At the beginning, I just stored the image in a string buffer to represent it with HttpResponse:
buffer = StringIO.StringIO()
canvas = pylab.get_current_fig_manager().canvas
canvas.draw()
pilImage = PIL.Image.fromstring("RGB", canvas.get_width_height(), canvas.tostring_rgb())
pilImage.save(buffer, "PNG")
# Send buffer in a http response the the browser with the mime type image/png set
return HttpResponse(buffer.getvalue(), mimetype="image/png")
However, I need to implement some javaScript in the html file to add more applications. For that reason, I have decided to save the image in a variable and plot it in the html file:
# serialize to HTTP response
response = HttpResponse(buffer.getvalue(), mimetype="image/png")
return render_to_response('eQL/dev/showImage.html', {'response':response})
My question is that I don't really know how to represent it in the html file because I didn't find any example doing it. Any one knows the answer?
Thanks in advance!
Do you mean that in your first implementation, your response was a PNG file, but now you wish to make the response an HTML file instead, containing the image?
Well firstly, you need to change the response MIME type from image/png to text/html or similar.
Secondly, I'm not sure why you are passing a HttpResponse object (containing the PNG data) into the template. Can the template even read that? Surely you just want to be passing the raw PNG data, not a HttpResponse object.
Finally, how to do it. Well as you may know, HTML isn't so great at embedding images. As with normal websites, you can include text in the page, but if you want an image, you need a separate file and link to it using the <img src="..." /> element. This is tricky to do dynamically: it means you need to setup two separate URLs (one for the PNG and one for the HTML), which run independently of one another (you can't just have one piece of code; you need one handler for generating the PNG and the other for generating the HTML), and have the HTML link to the PNG URL.
If that is too hard, there is another way out, but it is a bit hacky: data URLs. They let you include image data in the HTML page itself, so you only need to produce one response. Unfortunately it is not well supported in Internet Explorer pre-9. IE8 supports images less than 32K, IE7 and below don't work. See the example on Wikipedia -- you are aiming to generate something like this:
<img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUA
AAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO
9TXL0Y4OHwAAAABJRU5ErkJggg==" alt="Red dot" />
Basically, take the PNG data, and Base64-encode it (use Python's base64 library). Then just put "data:image/png;base64," in front of it, and set that as the URL for the img src. In other words, pass the Base64-encoded string to Django's template engine, and construct the URL as part of the img tag in the template.
