我想到了这个:
<?php
$dir = $_GET['dir'];
header('Content-type: image/jpeg');
$create = imagecreatetruecolor(150, 150);
$img = imagecreatefromjpeg($dir);
imagecopyresampled($create, $img, 0, 0, 0, 0, 150, 150, 150, 150);
imagejpeg($create, null, 100);
?>
它通过访问来工作:
哪个工作正常......但输出很糟糕:
有人可以将我的图像代码修改为 150 x 150 覆盖黑色区域...
谢谢。
解决方案:
<?php
$dir = $_GET['dir'];
header('Content-type: image/jpeg');
list($width, $height) = getimagesize($dir);
$create = imagecreatetruecolor(150, 150);
$img = imagecreatefromjpeg($dir);
$newwidth = 150;
$newheight = 150;
imagecopyresized($create, $img, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
imagejpeg($create, null, 100);
?>
最佳答案
使用imagecopyresized
:
$newwidth = 150;
$newheight = 150;
imagecopyresized($create, $image, 0, 0, 0, 0, $newwidth, $newheight, $oldwidth, $oldheight);
