The go-to solution for efficient display of (very) large images with zooming capability is to use tile pyramids. It is the principle behind every map viewer (google maps, apple plans, leaflet etc.). Our use case was to give our users the ability to view and add markers on building floor plans, with sufficient precision (hence a good zooming ability) and with good performance (network and interactions) in order to be usable on site. From a proof of concept using react-native-maps, we moved to a home made production component built with reanimated 2, fully written in javascript under 500 lines of code. This talk is a walk through the decision to start from scratch instead of using a third party native library.
