Plugin’s performance capabilities

The Image Cropper Plugin is created for a more convenient cropping of an image in a browser before sending it to the server.

1. Plugin allows to crop large-size images that do not fit your screen.
2. Plugin allows to set a necessary size of an image, e.g. 400×300
3. It is possible to switch on or off multiloading of files, it allows to upload one image or several images at a time.
4. It allows to send extra $_POST data to the server together with loading of an image.
5. It is possible to drag files on the loading pushbutton.
6. It allows to set a max size of an image by width or by height.
7. Plugin allows to set your own styles at hover or focus

How work the other plug-ins download and cropping images?

1. Upload photos to the server using the standard boot
2. After uploading photos you can meet plugin that allows you to crope the image but
   it does not cut it on the fly(immediately) and finds coordinate X and Y, the width and
   height and sends them back to the server and the server that had received the data
   (x,y,width,height) loads the images into the memory, checks it, cut it and than saves and
   gives the results of the work to the browser.

How Image cropper works?

1. Call the plug on the block, for example Upload image You
   can also drag image and throw them into the block if included the parameter drop: true
   when plugin is initializing.
2. If the crop: true then after the image selection screen appears window with proposal to
   mark necessary area and cut it, I want to note that the image will not load, it has loaded
   into the browser from your computer and will not send.
3. For your convenience it is made two fields for width and height, you can point width and
   height you need into them.
4. Mark the area you need on the photo and click Cut than the selected area with photowith
   other parameters ( tipe, size…) will send as a view POST request to the address you had
   indicated , but if you will click Ignore the image will send without cutting, that is to say
   in the whole format.
5. Server receives incoming data and stores your image in the format you want.

Additions:

– want you to pay attention if the image is very large it is reduced to the available size
of the window your web browser but the size of the image when it is cutting remains
unchanged it allows you to work with large formats, for example: 6000×4000.

– Also the system with the indication of the maximum size of the photo realized in the
plagin, for example, you want to limit your users with upload images no more than
1200px in width, than you should point the parameter maxWidth: 1200 plugin will check
the image size itself, and if it is more you specified, the image will automatically reduce
proportionally without losing of the quality, to 1200 in width.

Example:
you specified maxWidth: 1200 user loads the image in size200px width and height to 1600px
Eventually the image will reduce without losing of quality to the size of width 1200px
height: 874px, great, is not it? The same principle will work on maxHeigh, you can specify
two parameters at once and maxWidth and maxHeight.
