在Google云端存储中调整图片大小 [英] Resize image in Google Cloud Storage

问题描述

appengine / image软件包可以正常处理存储在Blobstore中的图像。但是，如何调整存储在Google云端存储中的图像的大小？

您可以将相同的图像服务与Google云端存储，特别是如果您使用Blobstore API上传图片。

Java中的示例代码：

  String fullName =/ gs /+ bucketName +/+ objectName; 
 Image picture = ImagesServiceFactory.makeImageFromFilename（fullName）; 
 Transform resize = ImagesServiceFactory.makeResize（maxWidth，maxHeight）; 
 picture = imagesService.applyTransform（resize，picture）; 
  

在Go中，您可以使用 BlobKeyForFile 函数：
$ b

BlobKeyForFile返回一个BlobKey用于Google存储文件。
文件名的格式应该是/ gs / bucket_name / object_name。

The appengine/image package works fine with images stored in Blobstore. However, what would be a good approach to resize images stored in Google Cloud Storage?

解决方案

You can use the same Image Service with the Google Cloud Storage, especially if you use Blobstore API for uploading images.

A sample code in Java:

String fullName = "/gs/" + bucketName + "/" + objectName;
Image picture = ImagesServiceFactory.makeImageFromFilename(fullName);
Transform resize = ImagesServiceFactory.makeResize(maxWidth, maxHeight);
picture = imagesService.applyTransform(resize, picture);

In Go, you can use BlobKeyForFile function:

BlobKeyForFile returns a BlobKey for a Google Storage file. The filename should be of the form "/gs/bucket_name/object_name".
