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 am currently attempting to code an app in react native for an android device. I have created a custom loading component and am using the to show a loading icon.
But, I want to use a custom gif loading icon that contains my app's colours. I have looked but I cannot seem to find anything, is it possible to do this?
react native does not support gif feature in its raw form. However, in order to reach what you want and use gifs in the application, you can take a look at the accepted answer on the subject;
How do I display an animated gif in React Native?
Then all you need to do is to use Image component instead of ActivityIndicator. And passing the relevant gif information to the image component.

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.
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
How can I use konvajs library with react native. If not, is there any other library which allows defining canvas object declaratively for react native?
React native doesn't use an html5 view, it render native code so you wouldn't be able to use konvasjs, take a look at react-native-canvas, and see if it fits what you need.
