The Telerik Platform does not provide such functionality out of the box. You implementation depends on your scenario.
1. Normally, the Camera app on the device should handle this feature. The Cordova Camera plugin actually starts the device Camera app which should take the picture, edit it and return it to your app. This is the most common scenario.
2. If you want to let the user take a picture and then convert it to grayscale in your app, you can use a third party JS library for this like camanJS
. This library lets you manipulate images. You can then do with them whatever you like.
Can you please share your app scenario, so that I can better understand what you need?
Do you want to have your say when we set our development plans?
Do you want to know when a feature you care about is added or when a bug fixed?
