CI Framework encapsulation of common image processing methods (thumbnails, watermarks, rotations, uploads, etc.) _php instances

This paper describes the common image processing methods of CI framework encapsulation. Share to everyone for your reference, as follows:

In fact, when the mobile phone, List diagram is best thumbnail, save the flow, this does not, and was moved to a hole, call a point on the stop, traffic owed to 90 blocks before the stop, I was drunk ...

Do not say nonsense, the following is the use of CI built-in processing of images of the library to write, little brother, the omission of the place please point out, thank you.

Here is the basic HTML code for the front-end:

 
  
 
  
 
  
 
  
 
  
 
                (
 
  
   
  best size X 80 pixels
 
   )
