how does IOS decode an image(JPEG or PNG) by CGImage ? Is this the most efficient way? -


We image an image (JPEG / PNG) in bitmap on iOS, generally, decoded by CGImage . Now I want to know whether it is the most efficient way to decode an image?

Or can anyone tell me that any API for us to decode an image by itself on iOS?

You can use to decode PNG files, but I do not know how much more Will be efficient. Apart from this you will not be able to use it with UIKit without making UI or CGI image, so what's the matter?

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

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...
