We have an application using touched screen, so user can use his finger to click the annotations.
But we found that it is too difficault to select annotation using finger. Is there a way to let it easy.

Thanks.

Which LEADTOOLS version and interface are you using?

Are you using Automated or non-automated annotations?

I am using 14, C++ ClassLib.
For example, I added line on the image and want to use my finger to select it.


Thanks.

In the .NET interface, you can adjust the sensitivity of the hittest with properties such as HitTest(AnnPoint testPoint, int buffer) & ControlPointsHitTestBuffer, etc.  Unfortunately, there's nothing like this in the other interfaces like CDLL, COM, CLIB, etc.

I have submitted a feature request regarding this functionality.  For your reference, the feature request number is 8404IDT.  If chosen for implementation, most feature requests are added at major releases (16, 17 etc.).

If this is an urgent need, please contact our custom development department by visiting http://www.leadtools.com/devservices/ for a quote.

It would be possible to implement it yourself though.  You would need to handle the "mouse" events and then do several hittests around the center point in the mouse event.
