By default, the DefaultOffsetY property is 0. The DefaultOffsetY property gets or sets a value that indicates the default y-offset of the layer. You can use the DefaultOffsetX / DefaultOffsetX properties to move the layer to a different position, which could be the initial position. Use the DefaultLayer(exDefLayerDefaultOffsetY) property to specify the default value for the DefaultOffsetY, before adding any layer. 

The following picture shows the position/size properties of the Layer, relative to the view / control:

The following properties determines the position / size / offset of the layer:

• Left, specifies the expression relative to the view, to determine the x-position to show the current layer on the control.
• Top, specifies the expression relative to the view, to determine the y-position to show the current layer on the control.
• Width, specifies the expression relative to the view, to determine the width to show the current layer on the control.
• Height, specifies the expression relative to the view, to determine the height to show the current layer on the control.

You can use the following properties to offset the view ( background + foreground ) inside the layer:

• DefaultOffsetX, gets or sets a value that indicates the default x-offset of the layer.
• OffsetX, gets or sets a value that indicates x-offset of the layer.
• OffsetXValid, validates the x-offset value of the layer.
• Value and ValueToOffsetX specifies the expression to convert the value to x-offset.
• DefaultOffsetY, gets or sets a value that indicates the default y-offset of the layer.
• OffsetY, gets or sets a value that indicates y-offset of the layer.
• OffsetYValid, validates the y-offset value of the layer.
• Value and ValueToOffsetY specifies the expression to convert the value to y-offset.

The following properties can be used to move / resize the picture on the layer's background:

• DisplayAs, retrieves or sets a value that indicates the way how the graphic is displayed on the layer's background.
• Left, specifies the expression relative to the view/current picture, to determine the x-position to show the current picture on the background.
• Top, specifies the expression relative to the view/current picture, to determine the y-position to show the current picture on the background.
• Width, specifies the expression relative to the view/current picture, to determine the width to show the current picture on the background.
• Height, specifies the expression relative to the view/current picture, to determine the height to show the current picture on the background.
