Installation

npm install react-native-image-marker --save
link
- react-native link (RN version < 0.60.0)
- auto link(RN version > 0.60.0)

iOS Pod Install (RN version < 0.60.0)

You can use pod instead of link. Add following lines in your Podfile:

pod 'RNImageMarker', :path => '../node_modules/react-native-image-marker'

API

the latest version
v1.1.x
v1.0.x
If you are using a version lower than 1.0.0, please go to v0.9.2

Save image to file

If you want to save the new image result to the phone camera roll, just use the CameraRoll-module from react-native.
If you want to save it to an arbitrary file path, use something like react-native-fs.
For any more advanced needs, you can write your own (or find another) native module that would solve your use-case.
