We need to capture a large receipt using React native camera, But the current version does not support Panorama view. Does anyone know if there is any alternate library available or how can this be achieved.

The point of the React Native app is to have an image shown, and use that particular image to set it as a Watch Face?
We're trying to find out if a 360 3D image rotation package for React Native exists for both Android and iOS. (or if it's straight forward without)
e.g. http://www.voidcanvas.com/demo/28823deye/ (thats just a jQuery example)
We're aware that there's things like React 360, and Google VR - however these put YOU in the center of the 360 environment, rather than putting an image sequence in the center - and letting you rotate the object.
currently react native doesn't have such things but you can use webview inside react native and use a javascript library to achive that. or you can implement yours with react native gesture handler
I am Working on react native camera library to taking bitmap.
For example, when we capture a image it return image path, height, width etc.
Instead of these i need bitmap.
The best way to achieve what you're looking to do is likely going to be to use the Native UI Components API for iOS and Android to implement a custom native image view that applies the effects you are looking for.
React Native doesn't give the option of accessing access the raw bitmap data of the React Native (aka. RCTImage) component.
I'm working on a react native app which works with a lot of animated GIFs.
I've tried using the react native documented library com.facebook.fresco:animated-gif:1.3.0 for animated gif support, yet, the performance of the default Image component is terrible, but using FastImage package I am able to get, at maximum, 10 gifs.
As there is the possibility of integrating the native libraries in React Native, I was wondering what could a solution to this problem?
I've tested a couple ways to increase the performance of loading multiple animated GIFs in React Native:
The better format for animated pictures is webp (Why?). Once compressed, it can be around 90% more lightweight to be loaded whether in your web app or your mobile app.
Facebook's Fresco library which is the documented recommended library for rendering gifs and webp files should be upgraded as it provides a better performance for multiple gif loading, and also the original fresco library should be added as a dependency - at the moment, to at least, 1.5.0 or higher, if possible w/ react-native:0.54 -.
FlatList can be optimized to remove anything that is not on the screen using removeClippedSubviews prop. Alternatively, there are third-party libraries such as recyclerlistview or lazy loading lists out there.
Using fast-image for caching can also be advantageous in some cases.
I hope to make an app based on React Native in which I can capture audio frame by frame and perform DSP analysis. Is there any library based on React Native that support this type of function? Thanks.
