图像处理库（裁剪和缩小，转换为base64等）

可能性

• 按比例减少图像的宽或高
• 按百分比减少图像大小
• 将图像适入到一定大小的框架中
• 任意调整图像大小
• 更改图像质量
• 输出生成的图像而不保存
• 在服务器上保存图像
• 为图像分配访问权限

需求

PHP >= 5.6.0

安装

在控制台运行

composer require lexinzector/picture

示例

use \Lexinzector\Picture\Picture;

// resize the image proportionally and save it on the server without changing the file extension
// the resulting image will not exceed 400 pixels in height and 300 in width
// that is, it will automatically fit into the required dimensions
$new_image = new Picture('url or path to file');
$new_image->autoimageresize(300, 400);
$new_image->imagesave($new_image->image_type, 'folder on the server');
$new_image->imageout();

// output to the screen without changing the file extension
$new_image = new Picture('url or path to file');
$new_image->autoimageresize(300, 400);
$new_image->imagesave($new_image->image_type, null);
$new_image->imageout();

// save on the server and select the output file type
$new_image = new Picture('url or path to file');
$new_image->autoimageresize(300, 400);
$new_image->imagesave('png', 'folder on the server');
$new_image->imageout();

// compress the file and display it on the screen
$new_image = new Picture('url or path to file');
$new_image->autoimageresize(300, 400);
