Update Plupload to version 2.X

[virgodesign]

Hi,

a few days ago was released to the public the plupload version 2.2.1 (​https://github.com/moxiecode/plupload/releases).

This release ships with an important enhancement related to image resize on client size: the bilinear resampling.

As they said: Improved quality for client-side image resizing (bilinear resampling)

This improvement let people resize images before upload on media library, but, this time, without loosing quality and colors.

This could be done in wordpress using the following filter

function resize_image_on_client_size( $defaults ) {
	
	$defaults['resize'] = array( 
		'width'   => 1600, 
		'height'  => 900, 
		'quality' => 80, 
		'crop' 	  => false
	);
	
	return $defaults;

}
add_filter( 'plupload_default_settings', 'resize_image_on_client_size' );

with this filter any user can resize images before upload them in the media library.

In these years we assisted to an incredible growth of powerful electronic devices (camera and smartphones) that captures images to high resolutions. images are becaming always bigger and bigger, and this could be a chance for users to start using an important feature such as image resize on client size.

I hope I've explained well this suggestion, and I hope this will take in consideration for the next wordpress release (4.7).

Thanks in advance.
