I am trying to add the media:thumnail element to the atom feed using SyndicationFeed .net class.
my code looks like the below
item.ElementExtensions.Add(new XElement("thumbnail",
new XAttribute("xmlns", "http://search.yahoo.com/mrss/"),
new XAttribute("url", "http://test.com/test.jpg/"),
new XAttribute("width", 200),
new XAttribute("height", 200)
).CreateReader()
);
which outputs as
<thumbnail url="http://test.com/test.jpg/" width="200" height="200" xmlns="http://search.yahoo.com/mrss/">
</thumbnail>
which is still seems to be valid atom feed. But as per client requirement, I want the format to be
"<media:thumbnail>". Could anyone please help me on this?
I even tried like this
item.ElementExtensions.Add("thumbnail", "http://search.yahoo.com/mrss/", 10);
which outputs as
<media:thumbnail>10</media:thumbnail>
but how do I add attributes instead of value?
finally I resolved the xml namespace issue after looking at this...
[SyndicationFeed change namespace prefix from a10 to atom
for some odd reason I never found that question before I post mine in stackoverflow :(

I am trying to extract thumbnails from source jpegs and save them to the file system, using the C# ImageSharp library. I see there is some mention of it in the intellisense for the component:
SixLabors.ImageSharp.Image.Metadata.ExifProfile.CreateThumbnail()
...but I can't seem to find any documentation for it or examples to call it correctly.
I did find this:
using SixLabors.ImageSharp;
using SixLabors.ImageSharp.PixelFormats;
using SixLabors.ImageSharp.Processing;
//method code:
Image<TPixel> thumbnail = image.Metadata.ExifProfile.CreateThumbnail<TPixel>();
https://docs.sixlabors.com/api/ImageSharp/SixLabors.ImageSharp.Metadata.Profiles.Exif.ExifProfile.html
...but I need to find where the TPixel type is to get it to work. VisualStudio doesn't recognize it and I can't seem to find a namespace or use it correctly:
"The type or namespace name 'TPixel' could not be found (are you missing a using directive or an assembly reference?)"
Legacy Windows .NET Framework could do this for System.Drawing.Image.Image.GetThumbnailImage() and it worked pretty well.
EDIT: Using tocsoft's answer, I changed the code to:
if (image.Metadata.ExifProfile != null)
{
Image<Rgba32> thumbnail = image.Metadata.ExifProfile.CreateThumbnail<Rgba32>();
thumbnail.Save(thumbnailPath, encoder);
}
...however, the image.Metadata.ExifProfile is null, which is unexpected since I know these source images have EXIF data.
EDIT: Actually, it's working now. Success! Thank you!
TPixel would be any of the pixel formats in the SixLabors.ImageSharp.PixelFormats namespace. But unless you are planning on interoperating with other systems that require the pixel data layed out in memory in specific ways you will likely just want to use Rgba32
Image<Rgba32> thumbnail = image.Metadata.ExifProfile.CreateThumbnail<Rgba32>();
I'm just a little desperate.
I installed the RSS Display extension.
http://typo3.org/extensions/repository/view/rss_display
Everything works fine, but I have just a little understanding problem.
I pull myself with fluid the Author for the current feed.
<feed:item.get value="author"/>
Than i look whats inside.
<f:debug><feed:item.get value="author"/></f:debug>
Thats the result.
SimplePie_Author prototype object
name => 'Name Name' (12 chars)
link => NULL
email => NULL
So what i need it's to get the name of the author.
Unfortunately i am not able to get the value.
I am really new in Fluid, Typo3.
Hopefully someone can help me.
One way to do this, is to create a fluid variable author and assign the author object to it. Then you can access the name using {author.name}.
To create a variable, you could use the ViewHelper <f:alias>, like this:
<f:alias map="{author: '{feed:item.get(value: \'author\')}'}">
{author.name}
</f:alias>
Another way would be to use the extension "vhs", which provides many tools for use with fluid. One of these tools is the ViewHelper <v:variable.set>, which could be used like this:
<v:variable.set name="author" value="{feed:item.get(value: 'author\'}"/>
{author.name}
This has the advantage that you don't need to use the variable within the tags of the ViewHelper.
There are other ways to reach the same goal, without defining variables, but this seems to be the easiest one to me.
I want to give my users the possibility to create document templates (contracts, emails, etc.)
The best option I figured out would be to store these document templates in mongo (maybe I'm wrong...)
I've been searching for a couple of hours now but I can't figure out how to render these document template with their data context.
Example:
Template stored in Mongo: "Dear {{firstname}}"
data context: {firstname: "Tom"}
On Tom's website, He should read: "Dear Tom"
How can I do this?
EDIT
After some researches, I discovered a package called spacebars-compiler that brings the option to compile to the client:
meteor add spacebars-compiler
I then tried something like this:
Template.doctypesList.rendered = ->
content = "<div>" + this.data.content + "</div>"
template = Spacebars.compile content
rendered = UI.dynamic(template,{name:"nicolas"})
UI.insert(rendered, $(this).closest(".widget-body"))
but it doesn't work.
the template gets compiled but then, I don't know how to interpret it with its data context and to send it back to the web page.
EDIT 2
I'm getting closer thanks to Tom.
This is what I did:
Template.doctypesList.rendered = ->
content = this.data.content
console.log content
templateName = "template_#{this.data._id}"
Template.__define__(templateName, () -> content)
rendered = UI.renderWithData(eval("Template.#{templateName}"),{name:"nicolas"})
UI.insert(rendered, $("#content_" + this.data._id).get(0))
This works excepted the fact that the name is not injected into the template. UI.renderWithData renders the template but without the data context...
The thing your are missing is the call to (undocumented!) Template.__define__ which requires the template name (pick something unique and clever) as the first argument and the render function which you get from your space bars compiler. When it is done you can use {{> UI.dynamic}} as #Slava suggested.
There is also another way to do it, by using UI.Component API, but I guess it's pretty unstable at the moment, so maybe I will skip this, at least for now.
Use UI.dynamic: https://www.discovermeteor.com/blog/blaze-dynamic-template-includes/
It is fairly new and didn't make its way to docs for some reason.
There are few ways to achieve what you want, but I would do it like this:
You're probably already using underscore.js, if not Meteor has core package for it.
You could use underscore templates (http://underscorejs.org/#template) like this:
var templateString = 'Dear <%= firstname %>'
and later compile it using
_.template(templateString, {firstname: "Tom"})
to get Dear Tom.
Of course you can store templateString in MongoDB in the meantime.
You can set delimiters to whatever you want, <%= %> is just the default.
Compiled template is essentially htmljs notation Meteor uses (or so I suppose) and it uses Template.template_name.lookup to render correct data. Check in console if Template.template_name.lookup("data_helper")() returns the correct data.
I recently had to solve this exact (or similar) problem of compiling templates client side. You need to make sure the order of things is like this:
Compiled template is present on client
Template data is present (verify with Template.template_name.lookup("data_name")() )
Render the template on page now
To compile the template, as #apendua have suggested, use (this is how I use it and it works for me)
Template.__define__(name, eval(Spacebars.compile(
newHtml, {
isTemplate: true,
sourceName: 'Template "' + name + '"'
}
)));
After this you need to make sure the data you want to render in template is available before you actually render the template on page. This is what I use for rendering template on page:
UI.DomRange.insert(UI.render(Template.template_name).dom, document.body);
Although my use case for rendering templates client side is somewhat different (my task was to live update the changed template overriding meteor's hot code push), but this worked best among different methods of rendering the template.
You can check my very early stage package which does this here: https://github.com/channikhabra/meteor-live-update/blob/master/js/live-update.js
I am fairly new to real-world programming so my code might be ugly, but may be it'll give you some pointers to solve your problem. (If you find me doing something stupid in there, or see something which is better done some other way, please feel free to drop a comment. That's the only way I get feedback for improvement as I am new and essentially code alone sitting in my dark corner).
I'm doing a bit tidy of the Content Manager and have a component that won't delete (not the same as my other question).
When I try to delete the component in question I get the following error
(8004032D) This item is in use.
Unable to delete Component (tcm:4-65020).
UtilitiesBL.AssertItemCanBeDeleted
UtilitiesBL.AssertItemCanBeDeleted
ComponentBL.Delete
Component.Delete
Request.Delete
When I use the Where Used tool on the component I get no results in the "Used In" tab, one result in the "Uses" tab, the "Blueprint Hierachy" shows it is not localized in any of my three child publications and no results in the "Published To" tab.
I have had a look in the Content Manager database to see if I can spot what is going wrong but not really found anything.
Any ideas?
Thanks in advance.
It looks like the Where Used tool in R5.3 isn't working correctly. The component in question is used in 15000 other components. I found this by using the TOM API directly.
var componentID = "tcm:4-65020";
TDS.TDSE tdse = new TDS.TDSE();
var component = (TDS.Component)tdse.GetObject(componentID, TDSDefines.EnumOpenMode.OpenModeView);
var whereUsedString = component .Info.GetListUsingItems();
Now comes the task of deleting all these links...
I saw that there are a lot of topics on simplehtmldom, but no one's problem seems to be mine- specifically, that it just 500s, even on the examples provided. I've found that I can include the file without an error, but if I then try to use file_get_html, it 500s. The only thing I found in the manual about installation is a possible problem with allow_fopen_url, which I do.
Something I'm missing?
Seems like too long since you asked this question, but since I came across this trying to solve this problem myself, I thought I'd post what worked for me.
I solved this problem by changing file_get_html to file_get_contents. Since I wanted to use the 'find' feature in simple_html_dom, I had to then convert the string to an object:
$string = file_get_contents(http://thedeadfallproject.com/)
$object = new simple_html_dom();
$object->load($string); // Load HTML from a string
