从以下链接下载裁剪图片的代码:

http://deepliquid.com/content/Jcrop.html

这是crop.php页面中的代码:

<?php

/**
* Jcrop image cropping plugin for jQuery
* Example cropping script
* @copyright 2008-2009 Kelly Hallman
* More info: http://deepliquid.com/content/Jcrop_Implementation_Theory.html
*/

if ($_SERVER['REQUEST_METHOD'] == 'POST')
{
$targ_w = $targ_h = 150;
$jpeg_quality = 90;

$src = 'demo_files/pool.jpg';
$img_r = imagecreatefromjpeg($src);
$dst_r = ImageCreateTrueColor( $targ_w, $targ_h );

imagecopyresampled($dst_r,$img_r,0,0,$_POST['x'],$_POST['y'],
$targ_w,$targ_h,$_POST['w'],$_POST['h']);

header('Content-type: image/jpeg');
imagejpeg($dst_r,null,$jpeg_quality);

exit;
}

// If not a POST request, display page below:

<script language="Javascript">

$(function(){

$('#cropbox').Jcrop({
aspectRatio: 1,
onSelect: updateCoords
});

});

function updateCoords(c)
{
$('#x').val(c.x);
$('#y').val(c.y);
$('#w').val(c.w);
$('#h').val(c.h);
};

function checkCoords()
{
if (parseInt($('#w').val())) return true;
alert('Please select a crop region then press submit.');
return false;
};

</script>

</head>

<body>
<!-- This is the image we're attaching Jcrop to -->
<img src="demo_files/pool.jpg" id="cropbox" />

<!-- This is the form that our event handler fills -->
<form action="crop.php" method="post" onsubmit="return checkCoords();">
<input type="hidden" id="x" name="x" />
<input type="hidden" id="y" name="y" />
<input type="hidden" id="w" name="w" />
<input type="hidden" id="h" name="h" />
<input type="submit" value="Crop Image" />
</form>

完美裁剪并成功显示裁剪后的图像。

但我想将裁剪后的图像保存到一个目录中。

我该怎么做?

最佳答案

试试这个:

imagejpeg($dst_r, 'yourfilename.jpg', $jpeg_quality);

// Remove from memory - don't forget this part
imagedestroy($dst_r);
