Codeigniter图像裁剪不工作 [英] Codeigniter image cropping is not working

问题描述

我在localhost上使用codeigniter 3.1。
我试图裁剪图像，但裁剪不工作。只调整工作大小。所以我启用了 Gd2 php扩展。

1。

  do_crop（$ filename）
 {
 $ this-> load-> library（'image_lib'）; 
 $ source_path ='uploads /'。 $ filename; 
 $ target_path ='uploads / thumb /'.$ filename; 
 
 $ config = array（
'image_library'=>'gd2'，
'source_image'=> $ source_path，
'new_image'=> $ target_path，
'maintain_ratio'=> FALSE，
'x_axis'=> 300，
'y_axis'=> 100，
）; 
 $ this-> image_lib-> initialize（$ config）; 
} 
  

图片大小= 1000X700 b
$ b

输出结果与原始图像大小相同 1000X700

2。

  public function do_crop（$ filename）
 {
 $ this- > load-> library（'image_lib'）; 
 $ source_path ='uploads /'。 $ filename; 
 $ target_path ='uploads / thumb /'.$ filename; 
 
 $ config = array（
'image_library'=>'gd2'，
'source_image'=> $ source_path，
'new_image'=> $ target_path，
'maintain_ratio'=> FALSE，
'width'=> 300，
'height'=> 300，
'x_axis'=> 350 ，
'y_axis'=> 50 
）; 
 $ this-> image_lib-> initialize（$ config）; 
} 
  

图片大小= 1000X700 b
$ b

第二个示例只调整图片大小（ 300x300 ），但未剪裁。

解决方案

  $ config = array（
'source_image'=> $ upload_path。$ image_data ['file_name']，
'maintain_ratio'=> FALSE，
'width'=> 220，
'height'=> 150，
'x_axis'=> 350，
 'y_axis'=> 50 
）; 
 $ this-> image_lib-> clear（）; 
 $ this-> image_lib-> initialize（$ config）; 
 $ this-> image_lib-> crop（）;

I am using codeigniter 3.1 on localhost. I am trying to crop images but cropping is not working. Only resize working. So i enabled Gd2 php extension.

1.

public function do_crop($filename)
{
    $this->load->library('image_lib');
    $source_path =  'uploads/' . $filename;
    $target_path =  'uploads/thumb/'.$filename;

    $config = array(
        'image_library' => 'gd2',
        'source_image' => $source_path,
        'new_image' => $target_path,
        'maintain_ratio' => FALSE,
        'x_axis' => 300,
        'y_axis' => 100,
    );
    $this->image_lib->initialize($config);
} 

Image size = 1000X700

The output result is same as original image size 1000X700

2.

public function do_crop($filename)
    {
        $this->load->library('image_lib');
        $source_path =  'uploads/' . $filename;
        $target_path =  'uploads/thumb/'.$filename;

        $config = array(
            'image_library' => 'gd2',
            'source_image' => $source_path,
            'new_image' => $target_path,
            'maintain_ratio' => FALSE,
            'width' => 300,
            'height' => 300,
            'x_axis' => 350,
             'y_axis' => 50
        );
        $this->image_lib->initialize($config);
    } 

Image size = 1000X700

And the 2nd example only resize (300x300) the image but not cropped.

解决方案

$config = array(
'source_image' => $upload_path.$image_data['file_name'],
'maintain_ratio' => FALSE,
'width' => 220,
'height' => 150,
'x_axis' => 350,
'y_axis' => 50
);
$this->image_lib->clear();
$this->image_lib->initialize($config);
$this->image_lib->crop();
