Members

BackBufferWidth

A UINT value representing the width of the back buffer in pixels.

BackBufferHeight

A UINT value representing the height of the back buffer in pixels.

BackBufferFormat

A D3DMFORMATenumeration value representing the back buffer's pixel format.

BackBufferCount

A UINT value representing the number of back buffers in the swap chain. There must always be at least one back buffer. If zero back buffers are requested the Direct3D Mobile middleware will override the setting with a default value of one. Multiple back buffers are useful to allow the system to rasterize at the same time it is waiting for a vertical retrace to present the previous frame.

MultiSampleType

A D3DMMULTISAMPLE_TYPEenumeration value indicating the type of multi-sample antialiasing that should be performed as part of the presentation process.

SwapEffect

A D3DMSWAPEFFECTenumeration value describing how the data from the back buffers should be transferred to the front buffer.

Windowed

A Boolean value defining the cooperative level for the window. The value TRUE indicates windowed cooperative level, and the value FALSE indicates full screen cooperative level.

EnableAutoDepthStencil

A Boolean value defining whether a depth or stencil buffer should be created with the swap chain. Set this value to TRUE to create the depth stencil buffer and FALSE to prevent creating it.

AutoDepthStencilFormat

A D3DMFORMATenumeration value representing the pixel format of the depth or stencil buffer.

Flags

Set this member to 0 or to D3DMPRESENTFLAG_LOCKABLE_BACKBUFFER.

FullScreen_PresentationInterval

A UINT value defining the number of vertical refresh intervals to wait before presenting the back buffer. Set this value to one of the D3DMPRESENT Values.

Requirements
