Hi

I am using the IELayer class and I am adjusting the height of a layer in code ...

Viewer.Image.GetLayer(1).Height = CInt(newHeight) * Calibration

However, the view does not update until I mouse click on the Viewer.

I have tried Refresh, Invalidate etc but nothing makes the layer jump to the correct size until I mouse click.

Ideas ?

Hi Jez

You must call ImageEnView1.Update() after modifying layer properties.

No, calling Update does not make the layer adjust to the new size set. I still have to mouse click somewhere.

Viewer.Image.GetLayer(1).Height = CInt(newHeight) * Calibration
Viewer.Update()

This makes no difference

Sorry, just clicked that you are using IEvolution.

Please use:

Viewer.UpdateImage()
