Question

I’ve been searching for a solution to this for some time and believe that it, at it’s core, isn’t possible.

I’m wondering if anybody has found a decent hack or bypass.

My issue is this:

I have an app that captures a photo, then that photo is used as a canvas that the user can tap on to place tags.

After the tags are placed the user uploads the photos and the tags get submitted to a client service for parsing.

If the photo is taken in landscape I need to detect if it’s landscape left or landscape right so that I can display it at the proper orientation when it gets to the canvas, and flip it the proper direction if the user changes to the opposite landscape mode.

How could I capture the orientation that the photo was taken in?

Answer 1

function getOrientation(o) {
    switch (o){
        case Titanium.UI.PORTRAIT:
            return 'portrait';
        case Titanium.UI.UPSIDE_PORTRAIT:
            return 'upside portrait';
        case Titanium.UI.LANDSCAPE_LEFT:
            return 'landscape left';
        case Titanium.UI.LANDSCAPE_RIGHT:
            return 'landscape right';
        case Titanium.UI.FACE_UP:
            return 'face up';
        case Titanium.UI.FACE_DOWN:
            return 'face down';
        case Titanium.UI.UNKNOWN:
            return 'unknown';
        }
    }
}

Ti.Gesture.addEventListener('orientationchange',function(e){
    Ti.API.info('Current Orientation: ' + getOrientation(Titanium.Gesture.orientation));
    var orientation = getOrientation(e.orientation);
    Titanium.API.info(
        "orientation changed = "+orientation+", is     portrait?"+e.source.isPortrait()+", orientation = "+Ti.Gesture.orientation + "is landscape?"+e.source.isLandscape()
    );
});

modified a bit from the KS but should do the trick.

this should do what the above doesn’t

Titanium.Media.showCamera({
    success:function(event) {
    var orientationWhilePictureTaken = Ti.Gesture.orientation;
        // all other camera code...
    }
});
