Question

在codeigniter代码中给文本作为图片上的水印无法正常运行。

public function new()
    {
        $this->load->library('image_lib');
        $config['sourse_image'] ='./SaveImage/fer.jpg';
        $config['wm_text'] = 'SaleScrap';
        $config['wm_type'] = 'text';
        $config['wm_font_path'] = 'system/fonts/texb.ttf';
        $config['wm_font_size'] = '16';
        $config['wm_font_color'] = 'ffffff';
        $config['wm_vrt_alignment'] = 'bottom';
        $config['wm_hor_alignment'] = 'center';
        $config['wm_padding'] = '20';
        $this->image_lib->initialize($config);
        if($this->image_lib->watermark())
        {
            echo "Success";
        }
        else
        {
            echo "Error";
        }
    }

代码不起作用，并且当代码运行时日志文件给出此错误

，无法给出输出

ERROR - 2018-08-29 11:49:54 --> You must specify a source image in your preferences.
ERROR - 2018-08-29 11:49:54 --> Your server does not support the GD function required to process this type of image.

Answer 1

解决方案1

$config['sourse_image'] ='./SaveImage/fer.jpg';

source_image的正确拼写

解决方案2。

您应该尝试使用以下结构：

$this->load->library('image_lib');
// Set your config up
$this->image_lib->initialize($config);
// Do your manipulation
$this->image_lib->clear();

如果没有任何效果，则错误可能实际上是整个问题。检查是否已安装gd，在Linux上会做

sudo yum list installed | grep php

如果未安装，请安装

sudo yum install php-gd-package-name

重新启动您的Apache

sudo服务httpd重新启动

图片水印在Codeigniter中不起作用
