我想在laravel上传中保存压缩图像。我找到了一个名为“干预/图像”的软件包。但是它具有调整大小的功能，不能压缩。
lzq0809 回答：如何在Laravel中压缩图像而不调整大小？
您可以简单地做到这一点：
public function compress($source,$destination,$quality = 75) {
$info = getimagesize($source);
if ($info['mime'] == 'image/jpeg') {
$image = imagecreatefromjpeg($source);
} elseif ($info['mime'] == 'image/gif') {
$image = imagecreatefromgif($source);
} elseif ($info['mime'] == 'image/png') {
$image = imagecreatefrompng($source);
}
imagejpeg($image,$quality);
return $destination;
}
目标可以与源相同
, <form action="{{route('resizeImagePost')}}" method="POST" enctype="multipart/form-data">
@csrf
<div class="row">
<div class="col-md-12">

<input type="file" name="image" placeholder="image" class ="image">
</div>
<div class="col-md-12">
<br/>
<button type="submit" class="btn btn-success">Upload Image</button>
</div>
</div>
</form>
public function resizeImagePost(Request $request)
{
$this->validate($request,[
'image' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',]);
$image = $request->file('image');
$upload_imagename = time().'.'.$image->getClientOriginalExtension();
$upload_url = public_path('/images').'/'.$upload_imagename;
$filename = $this->compress_image($_FILES["image"]["tmp_name"],$upload_url,40);
return back()
->with('success','Image Upload successful');
}
public function compress_image($source_url,$destination_url,$quality) {
$info = getimagesize($source_url);
if ($info['mime'] == 'image/jpeg')
$image = imagecreatefromjpeg($source_url);
elseif ($info['mime'] == 'image/gif')
$image = imagecreatefromgif($source_url);
elseif ($info['mime'] == 'image/png')
$image = imagecreatefrompng($source_url);
imagejpeg($image,$quality);
return $destination_url;
}
