DirectX 9 和 cef

如何解决DirectX 9 和 cef

我正在尝试在 directx 9 中集成 cef。没有错误发生,OnPaint 被调用,但是精灵没有被绘制。在此之前,我将缓冲区保存到 BMP 文件,但现在我决定渲染纹理。可能是什么问题?

void bCef::OnPaint(CefRefPtr<CefBrowser> browser,PaintElementType type,const RectList& dirtyRects,const void* buffer,int width,int height)
{
        m_RenderData.buffer = buffer;
        m_RenderData.width = width;
        m_RenderData.height = height;
        m_RenderData.dirtyRects = dirtyRects;
        m_RenderData.changed = true;
}
void bCef::setpDevice(IDirect3DDevice9* pDevice)
{
    if (m_RenderData.xzInit == false)
    {
        pDevice->CreateTexture(640,480,1,D3DUSAGE_DYNAMIC,D3DFMT_A8R8G8B8,D3DPOOL_DEFAULT,&m_RenderData.ttexture,NULL);
        D3DXCreateSprite(pDevice,&m_RenderData.tsprite);
        m_RenderData.xzInit = true;
    }
}
void bCef::draw()
{
    std::lock_guard<std::mutex> lock(m_RenderData.dataMutex);
    IDirect3DSurface9* pSurface;  
    m_RenderData.ttexture->GetSurfaceLevel(0,&pSurface);
    if (m_RenderData.changed)
    {
        D3DLOCKED_RECT LockedRect;
        if (FAILED(pSurface->LockRect(&LockedRect,nullptr,0))) {
            m_RenderData.cv.notify_all();
            return;
        }
        m_RenderData.changed = false;
        D3DSURFACE_DESC SurfaceDesc;

        pSurface->GetDesc(&SurfaceDesc);
        pSurface->LockRect(&LockedRect,0);

        auto dest = (unsigned char*)LockedRect.pBits;
        auto src = (const char*)m_RenderData.buffer;

        for (int i = 0; i < 480; ++i)
        {
            memcpy(dest,src,640 * 4);
            dest += LockedRect.Pitch;
            src += 640 * 4;
        }
        pSurface->UnlockRect();
    }
    D3DXVECTOR3* vector = new D3DXVECTOR3(0,0);
    m_RenderData.tsprite->Begin(D3DXSPRITE_ALPHABLEND);
    m_RenderData.tsprite->Draw(m_RenderData.ttexture,NULL,vector,0xFFFFFFFF);
    m_RenderData.tsprite->End(); 
    m_RenderData.cv.notify_all();
}
