Image processing software photoshop two powerful php image processing class 1

Copy the 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 merge with the background

How to use:
Automatic cropping:
The program will crop the largest square from the middle according to the size of the image , and abbreviate 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 cropping:
The program will fetch the image from the source image according to the specified position
$t->setSrcImg(" img/test.jpg");
$t->setCutType(2);//Indicates manual cutting
$t->setSrcCutPosition(100, 100);//Coordinates of the starting point of the source image
$t-> ;setRectangleCut(300, 200); // Cropping size
$t->setDstImg("tmp/new_test.jpg");
$t->createImg(300,200);
