D2DSurface Constructor

Summary

Initializes a new D2DSurface

Syntax

C++

public D2DSurface()

  
Public Function New()

public: 
D2DSurface();

Remarks

This constructor creates a new instance of a D2DSurface object.

After creating a new instance of D2DSurface, set the surface size using SurfaceSize Property.

Example

using Leadtools.Windows.D2DRendering; 
 
public void D2DSurfaceExample() 
{ 
   //Create a new instance of the D2DSurface object 
   D2DSurface d2dSurface = new D2DSurface(); 
 
   //Set the surface Size 
   d2dSurface.SurfaceSize = new Size(1000, 1000); 
 
   //Pass an empty rect to redraw the entire surface 
   d2dSurface.BeginDraw(Rect.Empty); 
 
   //Save the surface drawing state 
   D2DDrawingState drawingState = d2dSurface.Save(); 
 
   //Create a rect having the specified dimensions 
   Rect rect = new Rect(40, 40, 500, 200); 
 
   //Create a new instance of a brush from a new solid color brush 
   Brush fill = new SolidColorBrush(Colors.Green); 
 
   //Fill the interior of the specified rectangle using the specified brush 
   d2dSurface.FillRectangle(fill, rect); 
 
   //Create a new instance of the D2DPen object 
   D2DPen pen = new D2DPen(new SolidColorBrush(Colors.Red), 2); 
 
   //Draw an outline using the specified rectangle and D2DPen 
   d2dSurface.DrawRectangle(pen, rect); 
 
   //Restore the surface drawing state 
   d2dSurface.Restore(drawingState); 
 
   //End the Draw operation and invalidate the surface 
   d2dSurface.EndDraw(); 
 
   d2dSurface.Invalidate(Rect.Empty); 
}
