What is the best component for resizing and partitioning image in different sizes?

Question

I have already searched enough and there are some solutions to "resize" the images and create the "thumbnail" from an original image. I am creating a corporate network and would like to resize an image that the user uploads, and then as in all networks, enable clippings, then create several "thumbnail" (thumbnails) in different sizes.

Does anyone have a tip on how to do this? Canvas HTML 5? Bootstrap has some jQuery component that does this?

Answer 1

We can cut through the component jCrop(http://jcrop.org/). Already the resizing of the image in several other differentiated sizes we can create it through the native function of PHP imagecopyresized (php.net/manual/en/Function.imagecopyresized.php)
