IDirect3DMobileSwapChain::Present (Windows CE 5.0)
This method presents the contents of the next in the sequence of back buffers owned by the swap chain.
HRESULT Present( CONST RECT* pSourceRect, CONST RECT* pDestRect, HWND hDestWindowOverride, CONST RGNDATA* pDirtyRegion);
Parameters
- pSourceRect
[in] Pointer to a RECT structure that contains the source rectangle. This value must be NULL unless the swap chain was created with D3DMSWAPEFFECT_COPY or D3DMSWAPEFFECT_COPY_VSYNC (see D3DMSWAPEFFECT). If NULL, the entire source surface is presented. If the rectangle exceeds the source surface, the rectangle is clipped to the source surface. - pDestRect
[in] Pointer to a RECT structure containing the destination rectangle, in window client coordinates. This value must be NULL unless the swap chain was created with D3DMSWAPEFFECT_COPY or D3DMSWAPEFFECT_COPY_VSYNC. If NULL, the entire client area is filled. If the rectangle exceeds the destination client area, the rectangle is clipped to the destination client area. - hDestWindowOverride
[in] Destination window whose client area is taken as the target for this presentation. If this value is NULL, the hWndDeviceWindow member of D3DMPRESENT_PARAMETERS is taken. - pDirtyRegion
[in] This parameter is not used and must be set to NULL.
Return Values
If the method succeeds, the return value is D3DM_OK (see D3DM Values).
If the method fails, the return value can be E_OUTOFMEMORY or one of the following D3DMERR Values.
- D3DMERR_INVALIDCALL
- D3DMERR_MEMORYPOOLEMPTY
Remarks
This method performs identically to theIDirect3DMobileDevice::Present method.
If necessary, a stretch operation is applied to transfer the pixels within the source rectangle to the destination rectangle in the client area of the target window.
