cordova-screenshot

The Screenshot plugin allows your application to take screenshots of the current screen and save them into the phone.

This is a fork of https://github.com/gitawego/cordova-screenshot.git which supports only crosswalk on Android and the default webview on iOS. The goal is to allow a screenshot of the crosswalk display without needing to request permissions to the file system or the user's images. This works if you want to get screenshot of the app for support purposes.... The image can not be written to disk since the permission is not requested...thus may exhibit out of memory issues on devices with very high screen resolutions but with not much memory free.

##how to install

install it via cordova cli

cordova plugin add https://github.com/perry2of5/cordova-screenshot-crosswalk-ios-only.git

notice: On iOS, only jpg format is supported. On Android, only Crosswalk is supported

##usage

take screenshot and get it as Data URI

navigator.screenshot.URI(function(error,res){
  if(error){
    console.error(error);
  }else{
    html = '<img style="width:50%;" src="'+res.URI+'">';
    document.body.innerHTML = html;
  }
},50);

##usage in AngularJS TODO: update to use URI

.service('$cordovaScreenshot', ['$q', function ($q){
	return {
		capture: function (filename, extension, quality){
			extension = extension || 'jpg';
			quality = quality || '100';

			var defer = $q.defer();
			
			navigator.screenshot.save(function (error, res){
				if (error) {
					console.error(error);
					defer.reject(error);
				} else {
					console.log('screenshot saved in: ', res.filePath);
					defer.resolve(res.filePath);
				}
			}, extension, quality, filename);
			
			return defer.promise;
		}
	};
}])
