How to add a QR code to an image automatically
I am developing an image management app for IOS. User in this case takes an picture and the image is stored in content store (Not on device). If user wants to save the image, the image is uploaded to cloud along with its HASH and geo info. I want to add a QR code to the image in cloud which will have its HASH and Geo info stored in it.
Whats the best way to implement this module.
There is a manual process on how to accomplish this here-https://www.cnet.com/how-to/how-to-add-qr-codes-to-your-photos/# . I want to automate it for the images.作者: Jeremy Knothing 的来源 发布者： 2017 年 12 月 27 日
I suggest using Core Image. It has a QR code generator filter, as well as image compositing filters. You should be able to find a tutorial on generating QR codes using a CI filter, and another one on compositing images together. It should be straightforward to combine those 2 steps.作者: Duncan C 发布者: 2017 年 12 月 27 日
