i have an image target with 20px width, i want to draw a box / border to the image target when it's found..
could you tell me how ?
If you are using Unity, there are various ways to achieve this; one way would be to draw the lines connecting the 4 corners of the quad, using the GL draw functions:
The code for drawing couldbe triggered from within your own implementation of the ITrackableEventHandler, which allows you detecting when a target is found or lost, and which should be attached to the Image target (see also the DefaultTrackableEventHandler script, as an eample, attached to each Image Target)
