By default, the Width property is "width". If the Width property is empty, missing or invalid, it is considered "width". If valid, the value of evaluating the Width property indicates the width of the layer as shown in the picture bellow. Use the DefaultLayer(exDefLayerWidth) property to specify the default value for the Width property, before adding any layer. The LayerAutoSize property resizes all layers based on the picture of the first layer.
For instance:
- "0" indicates that the layer's width is 0
- "width / 2", half of the view or center of the control's view
- "width - 64", 64 pixels to the right side of the control's view
The Width property supports the following keywords:
- width keyword specifies the width in pixels of the control's view
- height keyword specifies the height in pixels of the control's view
Also, this property supports all constants, operators and functions defined here.
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.
The following picture shows the position/size properties of the Layer, relative to the view / 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.
