resize（）无法使用图像处理类 [英] resize() not working using Image manipulation class

问题描述

我一直在阅读这些文档，并尝试所有的东西来摆脱上传的图片，但我似乎找不到问题。

I’ve been reading the docs and trying everything to make thumbs out of uploaded images but I can’t seem to find the problem.

图片已上传，保存正确，但拇指不，它失败，没有错误输出。
这是我使用的代码：

Images are uploaded and saved correctly but thumbs are not, it fails with no error output. This is the code I’m using:

$data = $this->upload->data();

$config_image['image_library'] = 'gd';
$config_image['source_image'] = $data['full_path'];
$config_image['new_image'] = 'uploads/thumbs/';
$config_image['create_thumb'] = TRUE;
$config_image['maintain_ratio'] = TRUE;
$config_image['width'] = 750;
$this->load->library('image_lib', $config_image);

if ( !$this->image_lib->resize())
{
    $this->session->set_flashdata('message',  $this->image_lib->display_errors());
} 

此外，我想调整图像大小以适合max-width = 750，保持比率。是我做的正确做到了吗？
谢谢！

Also, I want to resize images to fit max-width=750, but maintain the ratio. Is what I’m doing correct to achieve that? Thanks!

推荐答案

你肯定要使用GD2。

You definitely have to use GD2.

CI的图像处理类有时候有些不自然。如果您无法正常工作，请查看 timthumb 。它是一个小的1文件php脚本，在运行时调整图像大小，并使用缓存系统。您只需通过图像标记的src属性传递所需的参数即可。很容易，工作非常好，比CI的图像处理类少得多的头痛。

CI's image manipulation class is a bit temperamental sometimes. If you can not get things to work, check out timthumb. It's a small 1 file php script that resizes images on the fly and uses a caching system. You just pass the required paramters through the src attribute of your image tag. Very easy, works very well and much less of a headache than CI's image manipulation class.
