Downloading Pictures from file repository not possible

Hi @drieder ,

what is here the final goal. Do you want to display these files/pictures  in Studio /vuforia view or these pictures  should be only downloaded to the mobile device and  should be used later with another applicaiton?

For example I have  here a simple project with 2d canvas with 2 widgets:

1.)2D video  Widget : "video-1"

2.) 2d Image Widget: "image-1"

The used the following javaScript definition for functions:

//////////////////// 
$scope.CallRequest=1
$scope.type="gif"
$scope.play= false
//=============
// 1.) call video MP4
// 2.) call picture gif
// 3.) call call other

////////////////////read video from repository
// if play =true will play the video
$scope.GetVideoFromTwxRepository = function(path, play) {
 $scope.CallRequest=1
 $scope.play =play
 $scope.$applyAsync(function() {
 
 $rootScope.$broadcast('app.mdl.CAD-Files-Repository.svc.LoadBinary',
 {"path":path}
 );} ,500 );
 
 console.log("after calling GetVideoFromTwx");
 
};

////////////////////////////////////////////////////////////////

//////////////////// read Image from repository
//type could be gif , bmp, jpg etc.
$scope.GetImageFromTwxRepository = function(path, type) {
 $scope.CallRequest=2
 $scope.type=type
 $scope.$applyAsync(function() {
 
 $rootScope.$broadcast('app.mdl.CAD-Files-Repository.svc.LoadBinary',
 {"path":path}
 );} ,500 );
 
 console.log("after calling GetImageFromTwx");
 
};
//------------------------------------------
$scope.$root.$on('LoadBinary-complete', function(event, args) { 
 console.log("LoadImage-complete event");
 
 console.log("name="+event.name)
 console.warn(args.data);
 
 console.warn(args.data[0]);
 
 if ( $scope.CallRequest==1) {
 console.log("$scope.CallRequest==1")
 
 var ret_str='data:video/mp4;base64,'+args.data[0].Content;
 $scope.view.wdg['video-1']['videosrc']=ret_str; 
console.warn($scope.view.wdg['video-1']['videosrc'])
 if($scope.play==true) 
 $timeout(function () { $scope.$root.$broadcast('app.view["Home"].wdg["video-1"].svc.play'); }, 500);
 
 } 
 else if($scope.CallRequest==2) {
 console.log("$scope.CallRequest==2")
 
 var ret_str='data:image/'+$scope.type+';base64,'+args.data[0].Content;
 $scope.view.wdg['image-1']['imgsrc']=ret_str; 
 
 } 
 else if ($scope.CallRequest==3) { 
 console.log("call other option")
 
 }
 
 });
//------------------------------------------

Here I used the TWX service 'app.mdl.CAD-Files-Repository.svc.LoadBinary' to load both image, or binary - this is the  more generic service  (for picture we have also LoadImage with also the corresponding -complete event)

In the service call in the function s. GetImageFromTwxRepository or  GetVideoFromTwxRepository the code will call the service LoadBinary and will pass a path argument.

When the service is completed Vuforia Studio/View will call the 'LoadBinary-Complete" event. In this event  the received data will be set  to image or video widgets. I used variable to make difference between the current call.  But this could be sometime disadvantageous - because the call is asynchronous and  there could be a problem  when we call the functions for different types successive without delay  (e.g. video und image) . There is definitely a better solution where we can synchronize - but here it should display only the general principle  (e.g. one possible solution is to use the LoadImage service and the corresponding event LoadImage-complete)

The following call:

//$rootScope.$on('modelLoaded', function() {
 
$scope.$on('$ionicView.afterEnter', function() {
 
$timeout( function () {$scope.GetImageFromTwxRepository('Image/n22-05-19-01.jpg','jpg');},500); 
 
$timeout( function () {$scope.GetImageFromTwxRepository('Image/muuu.jpg','jpg');},2000);
 
$timeout( function () {$scope.GetVideoFromTwxRepository('/web/c-belt-converyor.mp4',true);},10000);

});

The code above will be called when the  2D canvas is loaded and it will do:

- read a jpg file form repository and set it to the image-1 / delay 500ms   0.5sec

-read a second  jpg file form repository and set it to the image-1 / delay 2000ms -2sec

-read a video file from repository and set it to video-1 2d widget and play it / delay 10000ms - 10sec
