如何获得特定大小的相册照片 [英] How to get a specific size album photo

问题描述

我可以检索一张专辑的照片列表，但是有没有返回的照片数组中有不同的大小，但是我的问题是：有没有办法指定要返回的图像的尺寸。 p>

从/ photos调用返回的数组

  [id] => COVER PHOTO ID 
 [from] => Array（
 [name] => FB_USER NAME 
 [id] => FB_USER ID 
）
 [name] => PHOTO NAME 
 [picture] => https://photos-b.xx.fbcdn.net/hphotos-ash4/xxxxxxxxxxxx_s.jpg 
 [source] => https://sphotos-b.xx.fbcdn.net/hphotos-ash4/s720x720/xxxxxxxxxxxx_n.jpg 
 [height] => 540 
 [width] => 720 
 [images] => Array（
 [0] => Array（
 [height] => 1224 
 [width] => 1632 
 [source] => https：// sphotos-b.xx.fbcdn.net/hphotos-ash4/xxxxxxxxxxxx_o.jpg 
）
 
 [1] =>数组（
 [height] => 720 
 [width] => 960 
 [source] => https://sphotos-b.xx.fbcdn.net/hphotos-ash4/xxxxxxxxxxxx_n.jpg 
）
 
 [2] => Array（
 [height] => 540 
 [width] => 720 
 [source] => https：// sphotos- b.xx.fbcdn.net/hphotos-ash4/s720x720/xxxxxxxxxxxx_n.jpg 
）
 
 [3] => Array（
 [height] => 450 
 [width] => 600 
 [source] => https://sphotos-b.xx.fbcdn.net/hphotos-ash4/s600x600/xxxxxxxxxxxx_n.jpg 
）
 ...其他尺寸
 [link] => ALBUM LINK 
 [icon] => https://fbstatic-a.akamaihd.net/rsrc.php/v2/yz/r /StEh3RhPvjk.gif 
 [created_time] => 2012-10-14T03：52 ：17 + 0000 
 [updated_time] => 2012-10-14T03：52：17 + 0000 
）
  

有没有办法使用相册的封面照片ID与图/图片api来调整大小？

https://developers.facebook.com/docs/reference/api/using-pictures/

注意你可以做什么？width = xxxx& height = xxxx

解决方案

你不能。

如此文档所示，您只能调整图片，而不是照片。

• 图片只是一种方式to 表示一个对象，如个人资料，事件，页面或专辑。图片作为简单的表示，标志，描述或其他任何工作;这就是为什么他们应该适合任何形式的展示。


• 照片是您将在相册中找到的照片。这些是自己的对象，不需要一个图片来表示。我猜这个逻辑想让照片不能被调整大小，因为它们不应该被改变。

所以，你必须调整这些照片自己至少您可以为照片选择尺寸。

I can retrieve the list of photos of an album just fine and yes there are different sizes in the photos array returned, my question however is: is there any way to specify the dimensions of the image you want to return.

Is there any way to use the album's cover photo id with the graph /picture api to resize?

https://developers.facebook.com/docs/reference/api/using-pictures/

Notice how you can do ?width=xxxx&height=xxxx

解决方案

You can't.

As this doc indicates, you can only resize pictures, not photos.

• Pictures are only a way to represent an object, like a profile, an event, a page or an album. Pictures work as simple representation, logo, description or whatever ; this is why they should fit to any kind of displaying.
• Photos are the photos you will find in an album. These are objects themselves and doesn't need a picture to be represented. I guess the logic wants photos not to be resized, because they shouldn't be denaturalized.

So, you will have to resize these photos yourself. At least, you can choose a dimension for your photo.
