ckfinder image resize | 易学教程

问题

After selecting or uploading an image with the ckfinder, the user can change the width and height. I want it to automatically resize the image to the width and height the user sets. Is that possible?

I thaught that the ajax image resizer would fix that but can't get it to work. Somebody has experience with an automatic width and height resize-plugin?

In my config file of ckfinder I've got:

include_once "plugins/imageresize/plugin.php";

in the config.js I've got:

CKFinder.customConfig = function( config )
{
 config.extraPlugins = 'imageresize';
};

In the past, I've pre-defined an auto resize value to a specific folder in ckFinder so that any image a user uploads to that folder is resized. I do that by adding a little code to the config.php file like this:

// This next block sets the default max image size and quality
$config['Images'] = Array(
        'maxWidth' => 1600,
        'maxHeight' => 1200,
        'quality' => 80);

// Here we override those settings for a given folder
if(isset($_GET['currentFolder']) && urldecode($_GET['currentFolder']) == '/some-folder-name/'){
    $config['Images']['maxWidth'] = 150;
    $config['Images']['maxHeight'] = 150;
}

I would suspect you could do a similar hack, perhaps using $_SESSION values. Have your user select the auto-resize values they need and save it in their $_SESSION. Then in your config file, look for that session value. Something like:

if(isset($_SESSION['resize_w']) && isset($_SESSION['resize_h']) ){
    $config['Images']['maxWidth'] = $_SESSION['resize_w'];
    $config['Images']['maxHeight'] = $_SESSION['resize_h'];
}

Note that you'll need to call session_start() in your config.php file if you haven't already.

Ckeditor does't resize the image,it only change the height and width value. instead of resizing the image,Set the default width and height while clicking "ok" button. Here I replace the user entered height & width values with default height & width.

 CKEDITOR.on('dialogDefinition', function (ev) {

    var dialogName = ev.data.name,
        dialogDefinition = ev.data.definition;

    if (dialogName == 'image') {
        var onOk = dialogDefinition.onOk;

        dialogDefinition.onOk = function (e) {
            var width = this.getContentElement('info', 'txtWidth');
            width.setValue('200');//Set Default Width

            var height = this.getContentElement('info', 'txtHeight');
            height.setValue('200');//Set Default height

            onOk && onOk.apply(this, e);
        };
    }
});

In the "config.ascx" file change the value of variable as

Images.MaxWidth = 0; 
Images.MaxHeight = 0;
Images.Quality = 100;
