cameraRoll.getImage() throws error when selecting .tif image

Bug Reports
1

Before I can detect the selection of a .tif image in the resolve or reject function, Fuse throws an error in cameraRoll.getImage().

cameraRoll.getImage()
  .then(function(image) {
    console.log( JSON.stringify( image ) );
  }, function( error ) {
    console.log( error );
  }
);

Hi Karsten,

Sorry for not including the info in the first place. I wouldn’t mind if I can’t select a .tif image, but I don’t think it’s possible to specify this?

Error messages below are for selecting a .tif image on iOS 10.1.1, iPhone 6.
Fuse is latest release: 0.31.0 (build 8955)
Built with fuse build -t=ios on OSX 10.12.1.

Thanks :slight_smile:

I see this as more of a limitation than a bug, but I’ll create a support ticket for this anyway.

Although it depends a bit on how easy a fix would be, this probably won’t be a high-priority task, but I’ll keep you posted on any future updates.

Thanks!

As I said, I wouldn’t mind if you couldn’t use tiff images. My problem is that I cannot handle the error when a user selects one.

Oh, I’m sorry. Looks like I glossed over your post a bit too quick there.

So to be clear, it is the cameraRoll.getImage function that actually throws the exception? That’s certainly very strange. I haven’t yet looked into the details of how the module is implemented, but I would expect getImage to return a promise quickly before any image was selected at all.

Have you tried catching the exception by putting this code in a try/catch block?

Goodmorning Karsten,

yes, it is the cameraRoll.getImage function that triggers the error. Adding a try/catch block helps, indeed. Tested like so:

try {
  cameraRoll.getImage();
} catch( e ) {
  console.log( JSON.stringify( e ) );
}

and same errors as before, now in console.

Good morning.

Ok, that is definitively a bug, this should have returned a rejected promise instead. There has been another issue created for dealing with this.

In the meantime you’ll have to rely on a try/catch workaround.

:slight_smile:

Thanks! I have added the try/catch.

I have problem when trying to upload image larger than 3MB. Then app crushs and not throws exception. I tryed with this code but also the same. Any idea how to catch the exception ?

try {
cameraRoll.getImage();
} catch( e ) {
console.log( JSON.stringify( e ) );
}
