I try to use the TargetManager and to create a cuboid target. You can see it in the first picture.
But when I try to upload the front and the back it's not working.
You can see the Error in the picture: "Please provide an image with appropriate aspect ratio."
In the Last picture you can see, that the ratio is right. I searched in google for pictures with the width 880 pixels and the height 565, but its not working.
I tried ten pictures, even rotated them. Can someone help me?
It would be a good thing, if Vuforia would show the radio (and an example pixel number for width and height) in the TargetManager.
