This time I will bring you a detailed explanation of the steps for using PHPThumb image processing. What are theprecautionswhen using PHPThumb image processing? The following is a practical case, let's take a look.

Example:

resize(100, 100); //$thumb->show(); //把图片等比缩小到原来的百分数,比如50就是原来的50%。 $thumb->resizePercent(50); //$thumb->show(); //截取一个175px * 175px的图片,注意这个是截取,超出的部分直接裁切掉,不是强制改变尺寸。 $thumb->adaptiveResize(175, 175); //$thumb->show(); //从图片的中心计算,截取200px * 100px的图片。 $thumb->cropFromCenter(200, 100); //$thumb->show(); //截图,前两个参数分别是需要解出的图片的右上角的坐标X,Y。 后面两个参数是需要解出的图片宽,高。 $thumb->crop(100, 100, 300, 200); //$thumb->show(); //把图片顺时针反转180度 $thumb->rotateImageNDegrees(180); //$thumb->show(); try{ $thumb = PhpThumbFactory::create('./images/girl.png'); } catch(Exception $e){ throw $e; } $thumb->crop(100, 100, 300, 200); //$thumb->show(); $thumb->cropFromCenter(200, 100); //$thumb->show(); $thumb->adaptiveResize(250, 250)->createReflection(40, 80, 80, true, '#a4a4a4'); //反射(倒影),颜色是原图的边框色 //$thumb->show(); $thumb->rotateImage('CW'); //$thumb->show(); $thumb->adaptiveResize(300, 300); $thumb->save('./images/girl2.jpg','jpg'); //保存图片,第一个参数是保存后图片的name,第二个参数是图片的转换格式 $thumb->resize(150,200)->cropFromCenter(100)->show(); //链锁作用 }
