我有一个

PHP脚本,可以重新调整JPEG图像的大小.但是,由于某种原因,图像被扭曲,即使我将其编程为按比例计算x或y(取决于照片方向).质量是100,所以我不明白为什么它会使它们扭曲.我究竟做错了什么？

编辑

原始图像为3264px x 2448px

谢谢

代码：

$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);
