Hello,

I am using VTScada Light and I am encountering an issue where with I am getting ghosting of the images I am using tags to rotate.

I was wondering if anyone encountered this before.

Work Around.

I created a white box behind everything and tied its rotation to a tag value. I set the scaling to be really low (0-1 degree). That way every time the rotation would update the blank rectangle would be redrawn overwriting the ghosting.

What version of VTScada are you using and can you put your expression in the thread so we can see how you have gone about this? I'm not able to reproduce this using the following code. Note if you update the tag reference to your tag, you could paste the following onto your page to see if this works for you.

Replace 'BuildingA\MyDriver\ArrowPosition' with the full path to your tag.

             1, 1, 1, 1, 1 { Scaling              },
             0, PickValid([<BuildingA\MyDriver\ArrowPosition>], 0)          { Movement             },
             1, 0          { Visibility, Reserved },
             0, 0, 0       { Selectability        },
