When using MouseInteractLayers := [mlCreateShapeLayers]; in the TImageEnView, I can select an area for my shape both on and off the image displaying in the TImageEnView.

Selecting an area outside the image is causing problems. I there an easy way to limit the selection area when creating a shape to the coordinates of the displayed image so a shape cannot be create outside the image bounds?

Hi Jeff

You can use:

// Layers cannot be created or dragged beyond the background layer
ImageEnView1.LayerOptions := ImageEnView1.LayerOptions + [ loPreventOutOfBounds ];
