GrapeCity.Documents.Layout.Composition.Layer
Layer Class
Represents a drawing layer with visuals, optional clipping, and nested layers.
Namespace: GrapeCity.Documents.Layout.Composition
Assembly: DS.Documents.Imaging.dll
Syntax
public class LayerPublic Class LayerProperties
| Name | Description |
|---|---|
| BaseLayer | |
| BottomNestedLayer | Gets the nested Layer that appears below all other nested Layers on this Layer. |
| BottomVisual | Gets the Visual that appears below all other Visuals on this Layer. |
| ClipRect | Gets or sets a LayoutRect that affects the transformation matrix when clipping this Layer. If the CreateClipRegion delegate is not assigned, the ClipRect rectangle is also used as a clipping region. |
| CreateClipRegion | Gets or sets a delegate that creates a clipping region (IClipRegion) taking GcGraphics and Layer as parameters. The transformation matrix of the clipping region is defined by the ClipRect.Transform property. If the ClipRect property is not assigned, the transformation matrix of the owner View is used. |
| Draw | Gets or sets a delegate that accepts a GcGraphics object and a Layer and draws the layer on the graphics. |
| IsDetached | Gets true if this Layer is not associated with any Surface, false otherwise. |
| LayerAbove | Gets the sibling Layer that appears on top of the current Layer. |
| LayerBelow | Gets the sibling Layer that appears below the current Layer. |
| Name | Gets or sets the name of this Layer. |
| Surface | Gets the owner Surface object. |
| Tag | Gets or sets an object that contains arbitrary data associated with this layer. |
| TopNestedLayer | Gets the nested Layer that appears on top of all other nested Layers on this Layer. |
| TopVisual | Gets the Visual that appears on top of all other Visuals on this Layer. |
| View | If the current object is a Layer, gets the owner View. If the current object is a View, gets this object. |
| Visible | Gets or sets a value indicating whether this Layer is visible. |
Methods
| Name | Description |
|---|---|
| BringToFront() | Moves the layer to the front. It becomes the topmost nested layer of the base Layer or the top layer of the Surface. |
| CreateSpace() | Creates a Space object that represents an invisible helper rectangle for easy layout of other elements. |
| CreateSpace(int) | Creates a Space object that represents an invisible helper rectangle for easy layout of other elements. |
| CreateSubLayer() | Creates a nested Layer object and adds it on top of other nested layers. |
| CreateSubLayer(Action<GcGraphics, Layer>) | Creates a nested Layer object and adds it on top of other nested layers. |
| CreateSubView(float, float) | Creates a nested View object and adds it on top of other nested layers. |
| CreateSubView(float, float, Action<GcGraphics, Layer>) | Creates a nested View object and adds it on top of other nested layers. |
| CreateVisual(AnchorPoint[]) | Creates a Visual object that represents a polygon based on the given AnchorPoints. |
| CreateVisual(AnchorPoint[], Action<GcGraphics, Visual>) | Creates a Visual object that represents a polygon based on the given AnchorPoints. |
| CreateVisual(Contour, bool) | Creates a Visual object that represents an element drawing the Contour. |
| CreateVisual(Contour, bool, Action<GcGraphics, Visual>) | Creates a Visual object that represents an element drawing the Contour. |
| CreateVisual(Action<GcGraphics, Visual>) | Creates a Visual object that represents a drawing element. |
| CreateVisual(bool) | Creates a Visual object that represents a drawing element. |
| CreateVisual(int, bool) | Creates a Visual object that represents a drawing element. |
| Detach() | |
| GetNestedLayers() | Returns the array of nested layers and views on this Layer. |
| GetVisuals() | Returns the array of Visual objects. |
| MoveAbove(Layer) | Moves the current Layer to the position on top of the specified |
| MoveBelow(Layer) | Moves the current Layer to the position below the specified |
| SendToBack() | Moves the layer to the back. It becomes the bottom nested layer of the base Layer or the bottom layer of the Surface. |
| ToString() | Returns a string that represents the current Layer. |
