我正在使用 Blueimp/jQuery-File-Uploader以及适用于它的 Amazon S3 插件,一切正常,但我需要调整图像大小,使其最短边不超过或小于 640 像素。
我现在的代码是
global $s3;
if (isset($_REQUEST['_method']) && $_REQUEST['_method'] === 'DELETE') {
return "";
}
$upload = isset($_FILES['files']) ? $_FILES['files'] : null;
$info = array();
if ($upload && is_array($upload['tmp_name'])) {
foreach($upload['tmp_name'] as $index => $value) {
$fileTempName = $upload['tmp_name'][$index];
$file_name = (isset($_SERVER['HTTP_X_FILE_NAME']) ? $_SERVER['HTTP_X_FILE_NAME'] : $upload['name'][$index]);
$extension=end(explode(".", $file_name));
$rand = rand(1,100000000);
$sha1 = sha1($rand);
$md5 = md5($sha1);
$filename = substr($md5, 0, 8);
$fileName=$filename.".".$extension;
$fileName = $prefix.str_replace(" ", "_", $fileName);
$response = $s3->create_object($bucket, $fileName, array('fileUpload' => $fileTempName, 'acl' => AmazonS3::ACL_PUBLIC, 'meta' => array('keywords' => 'example, test'),));
if ($response->isOK()) {
$info[] = getFileInfo($bucket, $fileName);
} else {
// echo "<strong>Something went wrong while uploading your file... sorry.</strong>";
}
}
我已经编写了这段 PHP,但是我不确定如何让两者一起工作。
$image = new Imagick('test2.jpg');
$imageprops = $image->getImageGeometry();
$w=$imageprops['width'];
$h=$imageprops['height'];
$edge = min($w,$h);
$ratio = $edge / 640;
$tWidth = ceil($w / $ratio);
$tHeight = ceil($h / $ratio);
if ($imageprops['width'] <= 640 && $imageprops['height'] <= 640) {
// don't upscale
} else {
$image->resizeImage($tWidth,$tHeight,imagick::FILTER_LANCZOS, 0.9, true);
}
$image->writeImage("test2-resized.jpg");
如有任何帮助,我们将不胜感激
最佳答案
这是基于假设 OP 消息中的所有代码都是正确的,并且只是按要求重新安排了代码。
更新:四个赞成票(到目前为止)似乎表明 OP 不仅在代码方面而且在问题的严重性方面都是正确的。我做 OSS 是理所当然的,所以无论如何,如果你对这有任何兴趣,请明确告诉我,这样我们就可以在 github 上对此进行改进(任何行动都可以 - 赞成问题,赞成答案,发布评论,或其任意组合)。
function resize($imgName, $srcName)
{
$image = new Imagick($imgName);
$imageprops = $image->getImageGeometry();
$w=$imageprops['width'];
$h=$imageprops['height'];
$edge = min($w,$h);
$ratio = $edge / 640;
$tWidth = ceil($w / $ratio);
$tHeight = ceil($h / $ratio);
if ($imageprops['width'] <= 640 && $imageprops['height'] <= 640) {
return $imgName;
} else {
$image->resizeImage($tWidth,$tHeight,imagick::FILTER_LANCZOS, 0.9, true);
}
$extension=end(explode(".", $srcName));
// Change "/tmp" if you're running this on Windows
$tmpName=tempnam("/tmp", "resizer_").".".$extension;
$image->writeImage($tmpName);
return $tmpName
}
global $s3;
if (isset($_REQUEST['_method']) && $_REQUEST['_method'] === 'DELETE') {
return "";
}
$upload = isset($_FILES['files']) ? $_FILES['files'] : null;
$info = array();
if ($upload && is_array($upload['tmp_name'])) {
foreach($upload['tmp_name'] as $index => $value) {

$extension=end(explode(".", $file_name));
$rand = rand(1,100000000);
$sha1 = sha1($rand);
$md5 = md5($sha1);
$filename = substr($md5, 0, 8);

} else {
// `echo "<strong>Something went wrong while uploading your file... sorry.</strong>";`
}
unlink($fileTempName);
}
