Properties inherited from ImageOverlay | |
AutoScaleContent | AutoScaleContent [get, set] |
Defines whether or not the overlays in the canvas are automatically scaled according to the zoom factor. | |
CoordinateMode | Coordinates [get, set] |
Coordinate system usage (pixel or sub pixel). | |
Transform | NonScaledTransform [get] |

Interaction logic for RectSelectOverlay.xaml
|
getset |
Gets/sets whether the selected rect is set to the whole image region if a new image is assigned.
If set to false
the SelectedRect is not touched and must be set to a valid region externally.
|
getset |
The selected area.
Selected CVB rect.
|
get |
Gets the unselected margin.
The unselected margin identifies the unselected region of the image. Thus the inverted selected rect.
The Thickness
returned is in image pixels.
