几十年来，我们一直被承诺实现无纸化的未来，然而，尽管智能手机无处不在，但仍有大量纸张存在。更糟糕的是，在某些时候你会想要纸质文档的数字副本。
通常这意味着尝试使用扫描仪寻找某个地方，而这正变得越来越难做。多亏了拍照手机的卓越品质，人们很快就发现你可以拍摄出非常清晰的文件照片。但是，编辑和整理这些照片仍然很麻烦。特别是如果您需要扫描具有多页的文档。
幸运的是，Google Drive（Android和iOS）来救援了。它本质上是谷歌对 iCloud 和其他云存储解决方案的回应。Google Drive是完全免费的，除非您需要的存储空间超出基本级别。拥有Gmail帐户的每个人都可以访问Google 云端硬盘(Google Drive)。如果您拥有Android设备，则很可能已经安装了该应用程序。
Google Drive是 Google云(Cloud)应用套件的核心。Google Docs、Sheets和家庭中的其他应用程序都将其内容存储在您的Google Drive中。
虽然您可以很容易地将用手机或平板电脑拍摄的照片上传到云端硬盘，但该移动应用程序有一个(Drive)有点(somewhat )隐藏的功能，可以让您像复印机一样扫描文档。它会自动过滤和格式化图像以获得最大的易读性。一旦你知道去哪里，这是一个快速而简单的技巧，如果你必须一直处理纸张，你会经常使用。
值得注意的是，最新版本的 iOS 在Notes中还有一个新的文档扫描功能，在我的测试中效果同样好。我将单独写一篇关于该功能的评论。
使用Google Drive(Google Drive)扫描文档
假设您已经安装了该应用程序，您需要做的第一件事就是打开它。如果这是您第一次打开Google 云端硬盘(Google Drive)，则需要进行一些基本的一次性内务处理。您需要登录您的Google帐户，然后同意应用程序要求的任何权限。这些权限允许应用程序正常运行。如果您不允许其中任何一个，该应用程序仍然可以运行，但某些功能将无法启用。
完成后，您应该会看到Drive主屏幕，以及您已有的所有文档和图像。
点击加号(Tap the plus sign )以创建新文档。您将看到一系列选择。
现在点击“扫描”(tap on “Scan”)开始该过程。如果您使用的是 iOS，它会显示“使用相机”(“Use Camera”)。此时，您可能会被要求提供相机权限，然后才能继续。
注意相机取景器上的网格覆盖。使用它大致对齐文档。如果图像太暗，请点击闪电图标(tapping the lightning bolt icon)打开闪光灯。当您对图像感到满意时，点击蓝色按钮(tap the blue button)。然后你会被带到这个屏幕。
这是扫描的预览。 请注意(Notice)应用程序如何自动剪切背景并将图像拉直？很酷(Pretty)，对吧？
你现在有三个选择。如果您对图片不满意并想再试一次，请点击中间的图标再试一次(tap the middle icon to try again)。如果要添加第二个页面，请点击加号以添加另一个页面。(tap the plus sign to add another page.)如果您满意并想要保存文档，请点击复选标记以完成文档。(tap the check mark to finalize the document.)
这里的所有都是它的！该文件将作为PDF文档保存在您的Drive中。然后，您可以重命名、下载或将其移动到另一个文件夹。现在，如果您不再需要纸质副本，您可以负责任地回收它。多么酷啊？
Make Quick Digital Photocopies With Google Drive and Your Phone
We’νe been promised a paperless future for deсadеs now and yet, despіte smartphоnes being everywhere, there’s still a ton of paper around. To make things worse, at some pоint you аre going to want digital copies of paper documents.
Usually this means trying to find someplace with a scanner, which is becoming a harder thing to do day by day. Thanks to the excellent quality of camera phones, people soon figured out that you could just take photos of documents with perfect clarity. However, it’s still a hassle to edit and organize these photos. Especially if you need to scan a document with multiple pages.
Luckily Google Drive (Android & iOS) has come to the rescue. It’s essentially Google’s answer to iCloud and other cloud storage solutions. Google Drive is completely free, unless you need more than the base level of storage. Everyone with a Gmail account already has access to Google Drive. If you own an Android device, chances are that the app is already installed.
Google Drive is the heart of Google’s Cloud suite of apps. Google Docs, Sheets and other apps in the family all store their content in your Google Drive.
While you can upload the photos you take with a phone or tablet to Drive quite easily, the mobile app has a somewhat hidden feature that lets you scan documents like a photocopier. It automatically filters and formats the image for maximum legibility. Once you know where to go, this is a fast and simple trick you’ll use a lot if you have to deal with paper all the time.
It’s worth noting that the latest version of iOS also has a new document scanning feature in Notes, which works equally well in my tests. I’ll be writing up a separate review of that feature.
Scanning Documents with Google Drive
Assuming that you’ve already installed the app, the first thing you need to do is open it. If this is your first time opening Google Drive, there’s some basic, once-off housekeeping to do. You need to sign in to you Google account and then agree to any permissions the application asks for. These permissions allow the app to function properly. If you don’t allow any of them the app will still work, but some functions won’t be enabled.
With that done, you should see the Drive home screen, along with any documents and images you already have.
Tap the plus sign to create a new document. You’ll see a selection of choices.
Now tap on “Scan” to begin the process. If you’re on iOS it reads “Use Camera”. At this point you may be asked for camera permissions before you can proceed.
Note the grid overlay on the camera viewfinder. Use this to roughly align the document. If the image is too dark, switch on the flash by tapping the lightning bolt icon. When you are satisfied with the image, tap the blue button. Then you’ll be taken to this screen.
This is a preview of the scan. Notice how the app automatically cut out the background and straightened the image out? Pretty cool, right?
You now have three choices. If you are not happy with the picture and want to try again, tap the middle icon to try again. If you want to add a second page, tap the plus sign to add another page. If you’re happy and want to save the document, tap the check mark to finalize the document.
That’s all there is to it! The file will be saved as a PDF document in your Drive. You can then rename it, download it or move it to another folder. Now you can responsibly recycle the paper copy if you don’t need it anymore. How cool is that?
