mikkelking:snapshot

v1.1.7•Published 10 years ago

This package has not had recent updates. Please investigate it's current state before committing to using it in your project.

Meteor Camera Snapshot Package

Add it to your Meteor app with meteor add mikkelking:snapshot. 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. It also allows multiple sizes to be captured in one go. For example if you want a smaller thumbnail as well as the main image. In my app that uses this, I capture 3 sizes, small medium and large.

MeteorCamera.getPicture([options], callback)

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

options

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 An array of multipliers 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(error, data)

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.
