How can I utilize the Camera function in Cordova?

I am in the process of developing a Cordova app that will be compatible with both iOS and Android platforms. One of the key features of the app is the ability to display a camera within a specified frame. Below the camera frame, there will be a button labeled "Click" which, when pressed, will capture the current camera view and save it to the gallery. Additionally, there will be a slider on the left side of the camera frame that allows users to zoom in or out.

So far, I have experimented with using the "org.apache.cordova.camera" plugin, found at . However, I am struggling to figure out how to confine the camera view to a specific frame, as it currently defaults to opening in full screen mode. I would appreciate any suggestions for alternative plugins or methods that could help me achieve this goal.

Thank you for your help.

Answer №1

When using the camera plugin, it typically takes over the native camera function of the device, temporarily removing the user from your app until they either exit or take a picture. This is when you can handle the response data effectively.

For instance, you can have a button or link that, when clicked, triggers a function like the one below. Upon a successful capture, you can then load the image into a dynamically created canvas or similar element using the onSuccess callback.

navigator.camera.getPicture(onSuccess, onFail, { 
 quality            : 40,
 destinationType    : Camera.DestinationType.DATA_URL,
 encodingType       : Camera.EncodingType.JPEG,
 targetWidth        : 1600,
 targetHeight       : 1200,
 sourceType         : Camera.PictureSourceType.CAMERA,
 correctOrientation : true
});

The camera plugin simply launches the native camera app and captures the image.

If you're looking for more specific functionality, you may need to create a custom plugin for each platform.

Alternatively, you can explore using HTML5 (though it may only be compatible with newer Android devices, possibly >4.2). Raymond Camden wrote a blog post on this topic: http://www.example.com You can also visit HTML5Rocks for more information: http://www.example.com Keep in mind that zoom functionality may not be achievable with HTML5 alone.
