php 进行图片裁剪
作者:互联网
<?php $src_path = '1.jpg'; //创建源图的实例 $src = imagecreatefromstring(file_get_contents($src_path)); //裁剪开区域左上角的点的坐标 $x = 100; $y = 12; //裁剪区域的宽和高 $width = 200; $height = 200; //最终保存成图片的宽和高,和源要等比例,否则会变形 $final_width = 100; $final_height = round($final_width * $height / $width); //将裁剪区域复制到新图片上,并根据源和目标的宽高进行缩放或者拉升 $new_image = imagecreatetruecolor($final_width, $final_height); imagecopyresampled($new_image, $src, 0, 0, $x, $y, $final_width, $final_height, $width, $height); //输出图片 header('Content-Type: image/jpeg'); imagejpeg($new_image); imagedestroy($src); imagedestroy($new_image);
