在codeigniter中调整图像950 * 950的大小 [英] resize image 950*950 in codeigniter

问题描述

我在发布此问题时犹豫不决，因为我在这里看到了很多问题，但是所有答案都行不通。

I hesitated on posting this question cause I saw dozens of them here, but all the answers didn't work.

所以，我有这个工作代码。它会上传图片并获取缩略图。

So, I have this working code. It uploads picture and getting thumbnails.

我允许用户上传950 * 950图片。我想调整这些图片的大小以适合我的显示页面。

I allow users to upload a 950*950 pictures. I want to resize those pics to fit in my show page.

因此，这是调整大小的一部分：

So, here is part of the resize:

    $id=uniqid();

            $folder = $this->getDir($id);

            $dir=FCPATH.'upload/biz_photos/'.$folder.'/';

            if(!is_dir($dir)) {

              mkdirs($dir);
    }

    //handle img
    $des_file=$dir.$id.'.jpg';

            $thumb_file=$dir.$id.'.thumb.jpg';

            $info=getimagesize($org_file);

            if($info[0] <= 300) {

            copy($org_file,$dir.$id.'.jpg');

            }

            else

            {

            $this->load->library('image_lib');

            $config['image_library'] = 'GD2';

    $config['source_image']=$org_file;

    $config['new_image'] = $des_file;

        $config['overwrite']= true;

            $config['maintain_ratio'] =true;

            $config['width'] = 600;

            $config['height'] = floor(($info[1]/$info[0])*600);

            $this->image_lib->initialize($config);

        $this->image_lib->resize();

            // handle if there is any problem

            if ( ! $this->image_lib->resize()){

              echo $this->image_lib->display_errors();

            }

    }

就像我进行测试，然后上传950 * 950，然后检查上传的图片，其大小仍为原始图片的
。无需调整大小

Like when I test it, and upload a 950*950, and then check the uploaded image, the size still the original one. No resizing

推荐答案

几个小时后我确实发现了问题。因此，我有一个缩略图功能，我将原始图片传递给了它，而不是将新图片传递给了它（已缩放的图片）。

I did find the problem after few hours. So, I have a thumbnail function and I was passing to it the original picture instead of passing it the new picture (the sized picture).

谢谢
