Hey Nigel,

Using an ImageENView how can I tell if text objects are all or partially out of view. The viewport is smaller (ie shrinks) when objects all or partially out of view.

thanks in advance,

John

Hi John

You should compare the rect of the layer:

With the rect of the control.

Of course, the layer will be in bitmap units, and the control in screen units, so convert using, for e.g.:

Or just use (already in screen units):
