我已经将图像上传到文件夹。现在我想将该图像调整 3 次。首先将图像调整为 w：100，h：100，第二次将图像调整为 w：200，h：200，第三次将其调整为 300： 300

然后我在函数顶部加载了图像操作类库，如下所示:: $this->load->library('image_lib');

这是我的代码

$picturesData[$key][$key2] = $this->upload->data(); <<< this upload library is usable 

$file_name = $picturesData[$key][$key2]["file_name"];

//explode

$image_name = explode(".", $file_name);


//resize smallImage

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

$config['new_image'] = $path."/".$image_name[0]."_sSize";

// รูปที่เอามาใช้ในการ resize

$config['source_image'] = $picturesData[$key][$key2]["file_name"];

$config['create_thumb'] = TRUE;

$config['maintain_ratio'] = TRUE;

$config['width'] = 100;

$config['height'] = 100;

//mediumSize

$config['new_image'] = $path."/".$image_name[0]."_mSize";

$config['width'] = 200;

$config['height'] = 200;

//largeSize

$config['new_image'] = $path."/".$image_name[0]."_lSize";

$config['width'] = 300;

$config['height'] = 300;

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

$this->image_lib->resize();


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

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

}

这是我的错误！图像的路径不正确。

Your server does not support the GD function required to process this type of image.

The path to the image is not correct.

这似乎对我有用。$config['source_image'] = './图片路径/pic_name.jpg';

设置源路径..排除 base_url()

连续 Girish Sinha 回答 :: 改变这个 $config['source_image'] = $picturesData[$key][$key2]["file_name"]; 到 $config['source_image'] = $picturesData[$key][$key2]["full_path"];

尝试这个：-

$picturesData[$key][$key2] = $this->upload->data(); //this upload library is usable 
$file_name = $picturesData[$key][$key2]["file_name"];
//explode
$image_name = explode(".", $file_name);
//resize smallImage
$config['image_library'] = 'GD2';
$config['new_image'] = $path."/".$image_name[0]."_sSize.".$image_name[1];
//resize
$config['source_image'] = $picturesData[$key][$key2]["file_name"];
$config['create_thumb'] = TRUE;
$config['maintain_ratio'] = TRUE;
$config['width'] = 100;
$config['height'] = 100;
$this->image_lib->initialize($config);
$this->image_lib->resize();

//mediumSize
$config['new_image'] = $path."/".$image_name[0]."_sSize.".$image_name[1];
$config['width'] = 200;
$config['height'] = 200;
$this->image_lib->initialize($config);
$this->image_lib->resize();
//largeSize
$config['new_image'] = $path."/".$image_name[0]."_sSize.".$image_name[1];
$config['width'] = 300;
$config['height'] = 300;
$this->image_lib->initialize($config);
$this->image_lib->resize();
