The Challenges & Solutions
- To sync multiple pictures with associated comments even when the app is offline
- To place Dotty QR on image using a complex series of calculations
- To make the sync possible, we established a local database. We called a module to poll the internet connection status. The app attempts to upload any pending comment and update its status accordingly.
- We based the Dotty QR code on the co-ordinates of an image to conduct parameters based complex mathematical calculations and defining relevant image size & resolution.
