To install this open the terminal and jump into your project. I was wondering if anyone has done something similar, or knows what I have to do next. To use ImageViewer you need to install react-native-image-zoom-viewer package. I tried to achieve what I wanted by using translateX and translateY on the picture and setting these values to the event.focalX and event.focalY but it didn't give me the result i wanted because it shifts the image such that the top left corner is set on the focal point. The issue with this is that although it allows you to pinch and zoom into the picture, the zoom focal point is always in the centre of the picture. I've been able to implement the pinch feature as follows: I'm trying to use Reanimated and React-Native-Gesture-Handler to create a zoom effect similar to instagram that allows you to zoom into different regions of the picture and move around (exactly like instagram). The go-to solution for efficient display of (very) large images with zooming capability is to use tile pyramids. ![]()
