Add it to your Meteor app with meteor add mikkelking:camera. The api is super simple - there is only one function to call. This is based on mdg:camera, with improvements to keep the image inside the dialog box, and to allow portrait mode without stretching or clipping the image.

Prompt the user to take a photo with their device and get the picture as a Data URI in JPEG format.

options is an optional argument that is an Object with the following possible keys:

• width An integer that specifies the minimum width of the returned photo. Height is automatic, depending on orientation (landscape/portrait)
• magnification A multiplier which controls the size of the image - 2.286 (the default) gives you a picture size of 640x480, set to 1 gives you 280x210
• quality A number from 0 to 100 specifying the desired quality of JPEG encoding.

callback is a required argument that is a function that takes two arguments:

• error A Meteor.Error with a platform-specific error message.
• data A base64-encoded data URI for the image taken by the camera. This parameter can be used directly in the 'src' attribute of an image tag.

Warning: In the iOS simulator, the device camera is not accessible so you will get an error that says "source type 1 not available." I'm working on a fallback for iOS that will use the photo library when the camera is not available, but for now just test in your web browser, a physical device, or the Android simulator.
