In the process of website construction, there are a huge number of images to be processed. it is very tedious to use the PHP image function to process images.

It is very difficult for new users to master. Now we can use the PHPThumb class library to process images, including image size adjustment, image capturing, Image watermarking, and image rotation.

Example:

 resize(100, 100->resizePercent(50->adaptiveResize(175, 175->cropFromCenter(200, 100->crop(100, 100, 300, 200->rotateImageNDegrees(180->save( 'NewPath/Of/image.jpg ' );
