This example describes how Thinkphp calls the Image class to generate a thumbnail. Share it with you for your reference. The specific analysis is as follows:

The Image class of Thinkphp is in ThinkPHP/Extend/Library/ORG/Util/Image. class. php.

The call method is as follows:

Import ("ORG. util. image "); $ Img = new Image (); // instantiate an Image class object $ image_path = '. /Image path '; // if the current php file is in the APP_PATH path of Thinkphp //'. /'is the index. php file. // Because APP_PATH is defined and loaded through index. php. $ Image_info = $ Img: getImageInfo ($ image_path); // Obtain image information

The getImageInfo method obtains the width, height, type, size, mime, and other information of the image.

Creating thumbnails is simple.

The parameter requires img_path (source image path), thumb_name (thumbnail name, including Path), thumb_type (image type), Max_width (width), and Max_height (height ):

// Generate a thumbnail: $ Img: thumb2 ($ img_path, $ thumb_name, $ thumb_type, $ Max_width, $ Max_height );

Note that the width and height of the thumbnail cannot be greater than that of the source image. Otherwise, the generation will fail.
