How can you get the 3D space coordinates of the 4 corners of an ImageTarget in Vuforia Unity?
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I am able to detect images in Vuforia images and overlay 3d objects on them. But I want to draw borders around the ImageTarget.
The problem is that I can only get the center of it such as,
productTarget.transform.position
How can I get the corners of the image ? It is simply a 2D image but Vuforia doesn't have anything to help with this.

There is no way to detect coordinates of the corners, but you can manually calculate it.
This will help you to get the height and width of the image
for example: coordinates of upper left corner will be center - (width/2) - (height/2)

getSize() does not return pixels. It returns the size of this target in scene units. I don't know how to use the scene units to apply you calculation

I recommend you just make flat border which you want, and then just resize it on tracking image, because its scale is always the same and vuforia only moves the camera.

border
after tracking just child border to image

no, just make another object like your 3d model, but border

The problem is that I can't set the size to the same as I don't know the size of the target being tracked

you can get imageTarget.transform.localScale (as in question you have transform of your target), then make your border child of your target and set the same scale

I had something like this: "quad.transform.parent.localScale = transform.localScale" but the quad showed up much larger than the actual real-life target. I am using positional tracker in Vuforia and I had to provide the dimensions for each marker online in meters because of this.
