Two powerful PHP image processing classes 1_PHP tutorial

Copy code The code is as follows:

/**
* Basic image processing, used to complete image indentation and watermark addition
* When the watermark image exceeds the target image size, the watermark image can automatically adapt to the target image and shrink
* The watermark image can be set to match the background Degree of Merger

Usage:
Automatic cropping:
The program will crop the largest square from the middle according to the size of the image and shrink it according to the target size
$t->setSrcImg("img/test.jpg");
$t-> ;setCutType(1);//This sentence is OK
$t->setDstImg("tmp/new_test.jpg");
$t->createImg(60,60);
Manual cutting:
The program will take the image from the source image according to the specified position
$t->setSrcImg("img/test.jpg");
$t->setCutType(2) ;//Indicate manual cutting
$t->setSrcCutPosition(100, 100);//Coordinates of the starting point of the source image
$t->setRectangleCut(300, 200);//Cutting size
$t->setDstImg("tmp/new_test.jpg");
$t->createImg(300,200);
