I canvas another JavaScript canvas created through the canvas I am trying to attract But this is not working for me,

this is my code,

I think the problem was, when you attract the picture in the picture The canvas were trying, the image was not ready. So if you do this then it works perfectly:

And you can adjust the height and width of the dynamic canvas.

If you delete that window Open statement, correct it.

But there is a problem with canvas.toDataURL ()

when you try to canvas.toDataURL () A local file, it returns a security error (if you inspect it via Google Chrome) that means 

  wasted error: SECURITY_ERR: DOM exception 18

You can learn more about this error: (See if you are getting this error). Anyway, the root cause is solved, and a new problem is now completely: D. Otherwise better fortune!

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no.

Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
