Question

我已经将图片上传到文件夹。现在我想要调整该图像的大小3次。首先调整图像大小为w：100，h：100，第二次调整图像大小为w：200，h：200 ，第三个将其调整为300：300

然后我在图像操作类的库中加载了像这样的函数库:: $ this-＆gt; load-＆gt; 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'] ='。/ image path / pic_name.jpg';

设置源路径..排除base_url（）

试试这个： -

$picturesData[$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();

连续Girish Sinha回答::更改此$ config ['source_image'] = $ picturesData [$ key] [$ key2] [“file_name”]; to $ config ['source_image'] = $ picturesData [$ key] [$ key2] [“full_path”];

codeigniter中的库resize（）无法正常工作？
