我有一个PHP脚本,用于调整我的JPEG图片大小。但是,尽管我已经编程按照照片的方向比例计算x或y,但某种原因导致图像被扭曲了。质量为100,所以我不知道为什么会变形。我做错了什么?
编辑:
原始图像大小为3264px x 2448px

代码:
<?php
$im = ImageCreateFromJpeg('IMG_0168.jpg');
//Find the original height and width.
$ox = imagesx($im);
$oy = imagesy($im);
//Now we will determine the new height and width. For this example maximum height will
be 500px and the width will be 960px. To prevent inproper proportions we need to know
if the image is portrate or landscape then set one dimension and caluate the other.
$height = 500;
$width = 960;
if($ox < $oy) #portrate
{
$ny = $height;
$nx = floor($ox * ($ny / $oy));
}
else #landscape
{
$nx = $width;
$ny = floor($oy * ($nx / $ox));
}
//Then next two functions will create a new image resource then copy the original image
to the new one and resize it.
$nm = imagecreatetruecolor($nx, $ny);
imagecopyresized($nm, $im, 0, 0, 0, 0, $nx, $ny, $ox, $oy);
//Now we just need to save the new file.
imagejpeg($nm, 'smallerimagefile2.jpg', 100);
?>
