如何在codeigniter中调整图像大小？

Question

I trying to resize the image uploaded by user without cropping it. For that I am using following code.

$config['image_library'] = 'gd2';
    $config['source_image'] = './uploads/'.$name.'.jpg';
    $config['new_image']    = './uploads/'.$name.'.jpg';
    $config['create_thumb'] = TRUE;
    $config['maintain_ratio'] = TRUE;
    $config['width']     = 75;
    $config['height']   = 50;
    $this->image_lib->resize();
    $config['new_image']    = './uploads/'.$name.'.jpg';
    $config['width']     = 1000;
    $config['height']   = 400;
    $this->image_lib->initialize($config);
    $this->image_lib->resize();

but the problem is that it does not give me the image size 1000x400. it gives me the image with size 534x400. Is there any way to overcome this problem?

Answer 1

Change your $config['maintain_ratio'] = TRUE; to $config['maintain_ratio'] = FALSE;

Answer 2

Change this property to

$config['maintain_ratio'] = FALSE;
