Info LivePhoto -- Hidden Information in LivePhoto


Recently, I found an iOS app really interesting: LiveUseful, which can make a live photo with some information (photo or texts) behind it. You could spend a little money to support the developer, or use my "lite" version.

However, the function "gif convert to live photo" is not officially supported by iOS, so we need to install a free app: intoLive as the conversion engine.

最近,我發現一個有趣的 iOS app: LiveUseful,它可以製作 live photo,並且將一些資訊 (圖片或文字) 藏在圖片的後面。你可以花點小錢支持一下這位開發者,或者使用我的 "陽春" 版。

然而,由於 iOS 本身並沒有 gif 轉換至 live photo 的功能,所以我們需要安裝一個免費 app: intoLive 當作轉換格式的引擎。



How to use:

Just follow the instruction in info LivePhoto workflow, you will see the preview photo of the final result:

依照 Info LivePhoto workflow 裡的指示,最後你會看到結果的預覽圖:


In this stage, you can adjust the information photo's size, orientation, or colour...etc.

此時你可以調整資訊圖片的大小、旋轉角度及顏色 ...等等。


Then, intoLive will be launched, please choose the gif file you made to convert it to a live photo (I use default settings in intoLive). If no/wrong gif file was found, please refresh the user interface of intoLive.

接下來,intoLive 會自動啟動,請選擇剛製作好的 gif 檔以轉換成 live photo (我只使用 intoLive 的預設值)。如果發現找不到剛做好的 gif 檔,請刷新一下 intoLive 的使用者介面。

Info LivePhoto also supports the texts as information source, but the width of the textbox is optimised for (equally-wide) Chinese characters. You can tune below parameters to fit other languages (the height is ok, I guess).

Info LivePhoto 也支援輸入文字當作資訊,但是文字框的寬度是以等寬的中文字去最佳化。你可以調整下圖的參數以適配其他的語言 (高度部分應該是 ok 的,我猜啦 ....)


Final result demo (set the live photo on the lock screen):

What kinds of information?

You might think what kinds of information we need to make live photos for easy access? Actually there are many ....

e.g.
  • WiFi access QR code: When your friends come to your home for visiting, just show this QR code to them, no need to tell them the SSID and password. (I found the workflows made by other people are not so user-friendly, so you could use mine.)
  • vCard QR code: When you join a party or conference, if you would like to give your contact to some new friends, just show this QR code to save time from typing. (Workflow support of this is too limited, so please use online tool: QuickMark QR code Generator)

你可能想,哪種資訊有必要做成 live photo?事實上有很多 ....

例如:
  • 連結 WiFi 的 QR code:當你的朋友來你家拜訪你,只要給他們掃描這個 QR code,不用告訴他們 WiFi 帳號密碼 (我發現網上其他人寫的 workflow 不是很好用,所以用我寫的吧!)
  • 名片 QR code:當你參加一個聚會或研討會,如果你要給一個新朋友你的聯絡方式,只要給他們掃描這個 QR code 就可以省去打字的時間 (這部份 Workflow 的支援不夠,請用線上工具:QuickMark QR code Generator)
