ckeditor属性来调整图像大小

问题描述

ckeditor中有任何属性会在上传到指定维度后调整图片大小。例如：如果用户上传 1000 * 1000 px 的图像，并且不调整其大小，则可以是大屠杀。因为我保存和显示在同一页上，而不使用ajax刷新。
所有我想要的是从ckeditor上传时自动调整图像大小。
此外，是否有任何方式，我可以找到使用jquery是否有任何图像在用户保存的文本，因为用户可能或不可以上传图像，我使用inplace ckeditor。

Is there any property in ckeditor that will resize the image after uploading to a specified dimension. for eg: if user uploads a image of 1000*1000 px and doesn't resize it, it can be a massacre. As i am saving and displaying on the same page without refresh using ajax.All i want is to automatically resize image on upload from ckeditor.As well, is there any way that i can find using jquery whether there is any image in the text saved by user, as a user may or may not upload a image, I am using inplace ckeditor.

推荐答案

是一个优秀的伴侣到CKEditor，并允许在。

CKFinder is an excellent companion to CKEditor, and allows one to set the maximum size of an uploaded image in its configuration.

如果您不想使用它，您可以在PHP中自行调整图片大小，例如：

If you don't want to use that, you resize the image yourself in PHP with something like this:

<?php
$maxWidth  = 250;
$maxHeight = 500;

$size = getimagesize($url);
if ($size) {
    $imageWidth  = $size[0];
    $imageHeight = $size[1];
    $wRatio = $imageWidth / $maxWidth;
    $hRatio = $imageHeight / $maxHeight;
    $maxRatio = max($wRatio, $hRatio);
    if ($maxRatio > 1) {
        $outputWidth = $imageWidth / $maxRatio;
        $outputHeight = $imageHeight / $maxRatio;
    } else {
        $outputWidth = $imageWidth;
        $outputHeight = $imageHeight;
    }
}
?>
