出口
您已经设置了一些图像拇指
$configThumb = array();
$configThumb['image_library'] = 'gd2';
$configThumb['source_image'] = '';
$configThumb['create_thumb'] = TRUE;
$configThumb['maintain_ratio'] = TRUE;
$configThumb['width'] = 140;
$configThumb['height'] = 210;
好的。您还可以加载库$this->load->library('image_lib')代码>
那么,这些设置是如何将config设置到库的
再加上这个
$this->load->library('image_lib', $configThumb); # configuration variable
