jquery - How to add remote upload functionality to a web app with Instagram-like Filters to allow sharing on Facebook? -

-

i found awesome tutorial on building web app instagram-like filters: http://tutorialzine.com/2013/02/enhancing-the-instragram-filter-app/

the app allows drag picture computer browser , apply instagram-like filters it. can download image computer.

i trying figure out how add ability share photo on facebook. possible without remote upload?

i have 1 idea of using script:

<a class="share" onclick="window.open('http://www.facebook.com/sharer.php?s=100&amp;p[title]=title_goes_here&amp;p[summary]=copy_goes_here&amp;p[url]=http://www.website.com&amp;&amp;p[images][0]=http://www.webste.com/image_url.jpg', 'newwindow', 'width=555, height=315'); return false;"></a>

would possible replace "http://www.webste.com/image_url.jpg" part temporary image generated canvas?

thanks much!

i believe not possible.

the way pass image directly in url create data uri. while canvas have todataurl() method such representation of image, share.php not support passing , expects normal url. if did, such long url window.open break on browsers, @ least older ie versions seem have around 2kb url length limit.

one thing might able though upload image directly facebook getting user log in facebook appropriate privileges , posting https://graph.facebook.com/me/photos, have not tried javascript.

java - Copying object fields -

what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
