We're using cameraexclass version 1.30.
Executing the following shows the taken picture perfect on a panel
The button OK is pressed when you're ok with the given preview.
When it's for some reaseon not ok you can press "oOpnieuw" and then you can see the preview again.
However sometimes when quickly pushing buttons we're getting an error on the startPreview from within the class. See below.
