Type	Description
DxgiSwapChainDesc

FrameStatistics

Gets performance statistics about the last render frame.

uint

Methods

GetBuffer(uint, Guid)

Accesses one of the swap-chain's back buffers.

Declaration

public object GetBuffer(uint buffer, Guid riid)

Parameters

Type	Name	Description
uint	buffer	A zero-based buffer index.
Guid	riid	The type of interface used to manipulate the buffer.

Returns

Type	Description
object	A pointer to a back-buffer interface.

GetContainingOutput()

Get the output (the display monitor) that contains the majority of the client area of the target window.

Declaration

public DxgiOutput GetContainingOutput()

Returns

Type	Description
DxgiOutput	The output interface.

GetFullscreenState()

Get the state associated with full-screen mode.

Declaration

public bool GetFullscreenState()

Returns

Type	Description
bool	A value indicating whether to set the display state to windowed or full screen.

GetFullscreenState(out DxgiOutput)

Get the state associated with full-screen mode.

Declaration

public bool GetFullscreenState(out DxgiOutput target)

Parameters

Type	Name	Description
DxgiOutput	target	The output target when the mode is full screen.

Returns

Type	Description
bool	A value indicating whether to set the display state to windowed or full screen.

GetSurface(uint)

Accesses one of the swap-chain's back buffers.

Declaration

public DxgiSurface GetSurface(uint buffer)

Parameters

Type	Name	Description
uint	buffer	A zero-based buffer index.

Returns

Type	Description
DxgiSurface	A back-buffer surface.

Present(uint, DxgiPresentOptions)

Presents a rendered image to the user.

Declaration

public void Present(uint syncInterval, DxgiPresentOptions options)

Parameters

Type	Name	Description
uint	syncInterval	An integer that specifies how to synchronize presentation of a frame with the vertical blank.
DxgiPresentOptions	options	The swap-chain presentation options.

ResizeBuffers(uint, uint, uint, DxgiFormat, DxgiSwapChainOptions)

Changes the swap chain's back buffer size, format, and number of buffers. This should be called when the application window is resized.

Declaration

public void ResizeBuffers(uint bufferCount, uint width, uint height, DxgiFormat format, DxgiSwapChainOptions options)

Parameters

Type	Name	Description
uint	bufferCount	The number of buffers in the swap chain (including all back and front buffers). This number can be different from the number of buffers with which you created the swap chain.
uint	width	New width of the back buffer. If you specify zero, DXGI will use the width of the client area of the target window.
uint	height	New height of the back buffer. If you specify zero, DXGI will use the height of the client area of the target window.
DxgiFormat	format	A DXGI_FORMAT-typed value for the new format of the back buffer. Set this value to DXGI_FORMAT_UNKNOWN to preserve the existing format of the back buffer.
DxgiSwapChainOptions	options	The options for swap-chain behavior.

ResizeTarget(DxgiModeDesc)

Resizes the output target.

Declaration

public void ResizeTarget(DxgiModeDesc targetParameters)

Parameters

Type	Name	Description
DxgiModeDesc	targetParameters	A DXGI_MODE_DESC structure that describes the mode, which specifies the new width, height, format, and refresh rate of the target. If the format is DXGI_FORMAT_UNKNOWN, ResizeTarget uses the existing format.

SetFullscreenState(bool)

Sets the display state to windowed or full screen.

Declaration

public void SetFullscreenState(bool fullscreen)

Parameters

Type	Name	Description
bool	fullscreen	A value indicating whether to set the display state to windowed or full screen.

SetFullscreenState(bool, DxgiOutput)

Sets the display state to windowed or full screen.

Declaration

public void SetFullscreenState(bool fullscreen, DxgiOutput target)

Parameters

Type	Name	Description
bool	fullscreen	A value indicating whether to set the display state to windowed or full screen.
DxgiOutput	target	A pointer to an DXGIOutput interface for the output target that contains the swap chain.

Implements

IDisposable
