EndDraw ( ) : void	Ends drawing operations on the render target and indicates the current error state and associated tags. Drawing operations can only be issued between a {{BeginDraw}} and EndDraw call.BeginDraw and EndDraw are use to indicate that a render target is in use by the Direct2D system. Different implementations of SharpDX.Direct2D1.RenderTarget might behave differently when {{BeginDraw}} is called. An SharpDX.Direct2D1.BitmapRenderTarget may be locked between BeginDraw/EndDraw calls, a DXGI surface render target might be acquired on BeginDraw and released on EndDraw, while an WindowRenderTarget may begin batching at BeginDraw and may present on EndDraw, for example. The BeginDraw method must be called before rendering operations can be called, though state-setting and state-retrieval operations can be performed even outside of {{BeginDraw}}/EndDraw. After {{BeginDraw}} is called, a render target will normally build up a batch of rendering commands, but defer processing of these commands until either an internal buffer is full, the {{Flush}} method is called, or until EndDraw is called. The EndDraw method causes any batched drawing operations to complete, and then returns an HRESULT indicating the success of the operations and, optionally, the tag state of the render target at the time the error occurred. The EndDraw method always succeeds: it should not be called twice even if a previous EndDraw resulted in a failing HRESULT. If EndDraw is called without a matched call to {{BeginDraw}}, it returns an error indicating that BeginDraw must be called before EndDraw. Calling BeginDraw twice on a render target puts the target into an error state where nothing further is drawn, and returns an appropriate HRESULT and error information when EndDraw is called.
EndDraw ( long &tag1, long &tag2 ) : void	Ends drawing operations on the render target and indicates the current error state and associated tags. Drawing operations can only be issued between a BeginDraw and EndDraw call. BeginDraw and EndDraw are use to indicate that a render target is in use by the Direct2D system. Different implementations of SharpDX.Direct2D1.RenderTarget might behave differently when BeginDraw is called. An SharpDX.Direct2D1.BitmapRenderTarget may be locked between BeginDraw/EndDraw calls, a DXGI surface render target might be acquired on BeginDraw and released on EndDraw, while an SharpDX.Direct2D1.WindowRenderTarget may begin batching at BeginDraw and may present on EndDraw, for example. The BeginDraw method must be called before rendering operations can be called, though state-setting and state-retrieval operations can be performed even outside of BeginDraw/EndDraw. After BeginDraw is called, a render target will normally build up a batch of rendering commands, but defer processing of these commands until either an internal buffer is full, the Flush method is called, or until EndDraw is called. The EndDraw method causes any batched drawing operations to complete, and then returns an SharpDX.Result indicating the success of the operations and, optionally, the tag state of the render target at the time the error occurred. The EndDraw method always succeeds: it should not be called twice even if a previous EndDraw resulted in a failing SharpDX.Result. If EndDraw is called without a matched call to BeginDraw, it returns an error indicating that BeginDraw must be called before EndDraw. Calling BeginDraw twice on a render target puts the target into an error state where nothing further is drawn, and returns an appropriate SharpDX.Result and error information when EndDraw is called.
FillGeometry ( SharpDX geometry, SharpDX brush ) : void	Paints the interior of the specified geometry. If the opacityBrush parameter is not NULL, the alpha value of each pixel of the mapped opacityBrush is used to determine the resulting opacity of each corresponding pixel of the geometry. Only the alpha value of each color in the brush is used for this processing; all other color information is ignored. The alpha value specified by the brush is multiplied by the alpha value of the geometry after the geometry has been painted by brush. When this method fails, it does not return an error code. To determine whether a drawing operation (such as FillGeometry) failed, check the result returned by the EndDraw() or Flush() method.
FillOpacityMask ( Bitmap opacityMask, Brush brush, OpacityMaskContent content ) : void	Applies the opacity mask described by the specified bitmap to a brush and uses that brush to paint a region of the render target. For this method to work properly, the render target must be using the F:SharpDX.Direct2D1.AntialiasMode.Aliased antialiasing mode. You can set the antialiasing mode by calling the M:SharpDX.Direct2D1.RenderTarget.SetAntialiasMode(SharpDX.Direct2D1.AntialiasMode) method. This method doesn't return an error code if it fails. To determine whether a drawing operation (such as {{FillOpacityMask}}) failed, check the result returned by the M:SharpDX.Direct2D1.RenderTarget.EndDraw(System.Int64@,System.Int64@) or M:SharpDX.Direct2D1.RenderTarget.Flush(System.Int64@,System.Int64@) methods.
FillRoundedRectangle ( RoundedRectangle roundedRect, Brush brush ) : void	Paints the interior of the specified rounded rectangle. This method doesn't return an error code if it fails. To determine whether a drawing operation (such as {{FillRoundedRectangle}}) failed, check the result returned by the M:SharpDX.Direct2D1.RenderTarget.EndDraw(System.Int64@,System.Int64@) or M:SharpDX.Direct2D1.RenderTarget.Flush(System.Int64@,System.Int64@) methods.
Flush ( ) : void	Executes all pending drawing commands. This command does not flush the device that is associated with the render target. Calling this method resets the error state of the render target.
RenderTarget ( Factory factory, SharpDX.DXGI.Surface dxgiSurface, SharpDX.Direct2D1.RenderTargetProperties properties ) : System	Creates a render target that draws to a DirectX Graphics Infrastructure (DXGI) surface. To write to a Direct3D surface, you obtain an SharpDX.DXGI.Surface and pass it to the {{CreateDxgiSurfaceRenderTarget}} method to create a DXGI surface render target; you can then use the DXGI surface render target to draw 2-D content to the DXGI surface. A DXGI surface render target is a type of SharpDX.Direct2D1.RenderTarget. Like other Direct2D render targets, you can use it to create resources and issue drawing commands. The DXGI surface render target and the DXGI surface must use the same DXGI format. If you specify the {{DXGI_FORMAT_UNKOWN}} format when you create the render target, it will automatically use the surface's format.The DXGI surface render target does not perform DXGI surface synchronization. To work with Direct2D, the Direct3D device that provides the SharpDX.DXGI.Surface must be created with the D3D10_CREATE_DEVICE_BGRA_SUPPORT flag.For more information about creating and using DXGI surface render targets, see the {{Direct2D and Direct3D Interoperability Overview}}.When you create a render target and hardware acceleration is available, you allocate resources on the computer's GPU. By creating a render target once and retaining it as long as possible, you gain performance benefits. Your application should create render targets once and hold onto them for the life of the application or until the render target's {{EndDraw}} method returns the {{D2DERR_RECREATE_TARGET}} error. When you receive this error, you need to recreate the render target (and any resources it created).

Drawing operations can only be issued between a {{BeginDraw}} and EndDraw call.BeginDraw and EndDraw are use to indicate that a render target is in use by the Direct2D system. Different implementations of SharpDX.Direct2D1.RenderTarget might behave differently when {{BeginDraw}} is called. An SharpDX.Direct2D1.BitmapRenderTarget may be locked between BeginDraw/EndDraw calls, a DXGI surface render target might be acquired on BeginDraw and released on EndDraw, while an WindowRenderTarget may begin batching at BeginDraw and may present on EndDraw, for example. The BeginDraw method must be called before rendering operations can be called, though state-setting and state-retrieval operations can be performed even outside of {{BeginDraw}}/EndDraw. After {{BeginDraw}} is called, a render target will normally build up a batch of rendering commands, but defer processing of these commands until either an internal buffer is full, the {{Flush}} method is called, or until EndDraw is called. The EndDraw method causes any batched drawing operations to complete, and then returns an HRESULT indicating the success of the operations and, optionally, the tag state of the render target at the time the error occurred. The EndDraw method always succeeds: it should not be called twice even if a previous EndDraw resulted in a failing HRESULT. If EndDraw is called without a matched call to {{BeginDraw}}, it returns an error indicating that BeginDraw must be called before EndDraw. Calling BeginDraw twice on a render target puts the target into an error state where nothing further is drawn, and returns an appropriate HRESULT and error information when EndDraw is called.

Calling BeginDraw twice on a render target puts the target into an error state where nothing further is drawn, and returns an appropriate SharpDX.Result and error information when EndDraw is called.

public EndDraw ( long &tag1, long &tag2 ) : void
tag1	long	When this method returns, contains the tag for drawing operations that caused errors or 0 if there were no errors. This parameter is passed uninitialized.
tag2	long	When this method returns, contains the tag for drawing operations that caused errors or 0 if there were no errors. This parameter is passed uninitialized.

FillGeometry() публичный Метод

Paints the interior of the specified geometry.

If the opacityBrush parameter is not NULL, the alpha value of each pixel of the mapped opacityBrush is used to determine the resulting opacity of each corresponding pixel of the geometry. Only the alpha value of each color in the brush is used for this processing; all other color information is ignored. The alpha value specified by the brush is multiplied by the alpha value of the geometry after the geometry has been painted by brush. When this method fails, it does not return an error code. To determine whether a drawing operation (such as FillGeometry) failed, check the result returned by the EndDraw() or Flush() method.

public FillGeometry ( SharpDX geometry, SharpDX brush ) : void
geometry	SharpDX	The geometry to paint.
brush	SharpDX	The brush used to paint the geometry's interior.
Результат	void

FillOpacityMask() публичный Метод

Applies the opacity mask described by the specified bitmap to a brush and uses that brush to paint a region of the render target.

For this method to work properly, the render target must be using the F:SharpDX.Direct2D1.AntialiasMode.Aliased antialiasing mode. You can set the antialiasing mode by calling the M:SharpDX.Direct2D1.RenderTarget.SetAntialiasMode(SharpDX.Direct2D1.AntialiasMode) method. This method doesn't return an error code if it fails. To determine whether a drawing operation (such as {{FillOpacityMask}}) failed, check the result returned by the M:SharpDX.Direct2D1.RenderTarget.EndDraw(System.Int64@,System.Int64@) or M:SharpDX.Direct2D1.RenderTarget.Flush(System.Int64@,System.Int64@) methods.

public FillOpacityMask ( Bitmap opacityMask, Brush brush, OpacityMaskContent content ) : void
opacityMask	Bitmap	The opacity mask to apply to the brush. The alpha value of each pixel in the region specified by sourceRectangle is multiplied with the alpha value of the brush after the brush has been mapped to the area defined by destinationRectangle.
brush	Brush	The brush used to paint the region of the render target specified by destinationRectangle.
content	OpacityMaskContent	The type of content the opacity mask contains. The value is used to determine the color space in which the opacity mask is blended.
Результат	void

FillRoundedRectangle() публичный Метод

Paints the interior of the specified rounded rectangle.

This method doesn't return an error code if it fails. To determine whether a drawing operation (such as {{FillRoundedRectangle}}) failed, check the result returned by the M:SharpDX.Direct2D1.RenderTarget.EndDraw(System.Int64@,System.Int64@) or M:SharpDX.Direct2D1.RenderTarget.Flush(System.Int64@,System.Int64@) methods.

public FillRoundedRectangle ( RoundedRectangle roundedRect, Brush brush ) : void
roundedRect	RoundedRectangle	The dimensions of the rounded rectangle to paint, in device-independent pixels.
brush	Brush	The brush used to paint the interior of the rounded rectangle.
Результат	void

Flush() публичный Метод

Executes all pending drawing commands.

This command does not flush the device that is associated with the render target. Calling this method resets the error state of the render target.

RenderTarget() публичный Метод

Creates a render target that draws to a DirectX Graphics Infrastructure (DXGI) surface.

To write to a Direct3D surface, you obtain an SharpDX.DXGI.Surface and pass it to the {{CreateDxgiSurfaceRenderTarget}} method to create a DXGI surface render target; you can then use the DXGI surface render target to draw 2-D content to the DXGI surface. A DXGI surface render target is a type of SharpDX.Direct2D1.RenderTarget. Like other Direct2D render targets, you can use it to create resources and issue drawing commands. The DXGI surface render target and the DXGI surface must use the same DXGI format. If you specify the {{DXGI_FORMAT_UNKOWN}} format when you create the render target, it will automatically use the surface's format.The DXGI surface render target does not perform DXGI surface synchronization. To work with Direct2D, the Direct3D device that provides the SharpDX.DXGI.Surface must be created with the D3D10_CREATE_DEVICE_BGRA_SUPPORT flag.For more information about creating and using DXGI surface render targets, see the {{Direct2D and Direct3D Interoperability Overview}}.When you create a render target and hardware acceleration is available, you allocate resources on the computer's GPU. By creating a render target once and retaining it as long as possible, you gain performance benefits. Your application should create render targets once and hold onto them for the life of the application or until the render target's {{EndDraw}} method returns the {{D2DERR_RECREATE_TARGET}} error. When you receive this error, you need to recreate the render target (and any resources it created).
