I attempted to add a Cylinder target into ImageTarget database. I entered top diameter: 0.06, bottom diameter: 0.06 and side: 0.0785. After I created the entry into the database, I was asked to upload the image and then I uploaded the image from vuforia-samples-core-android-6-0-112/media/target_cylinder.jpg. However, it fails and the error message as "... the image of the width and height ratio should be 2.401 which close to what I entered 0.06*3.14/0.785.
Please provide a step by step sample how to add a cylinder target into ImageTarget Database.
