彩色圖像獲取和深度獲取的程序十分相似窖铡，前面的部分不多說了，只說不同的地方。

Update函數(shù)里面需要把Kinect獲取的彩色數(shù)據(jù)（Yuy2格式）轉(zhuǎn)換成BGRA格式吊圾，這是為了方便處理：

        // 獲取彩色圖像格式
        if (SUCCEEDED(hr))
        {
            hr = pColorFrame->get_RawColorImageFormat(&imageFormat);
        }

        if (SUCCEEDED(hr))
        {
            // 如果是BGRA格式顶捷，就直接把pBuffer指向pColorFrame的數(shù)據(jù)頭挂绰，否則需要轉(zhuǎn)化成BGRA
            if (imageFormat == ColorImageFormat_Bgra)
            {
                hr = pColorFrame->AccessRawUnderlyingBuffer(&nBufferSize, reinterpret_cast<BYTE**>(&pBuffer));
            }
            else if (m_pColorRGBX)
            {
                pBuffer = m_pColorRGBX;
                nBufferSize = cColorWidth * cColorHeight * sizeof(RGBQUAD);
                hr = pColorFrame->CopyConvertedFrameDataToArray(nBufferSize, reinterpret_cast<BYTE*>(pBuffer), ColorImageFormat_Bgra);            
            }
            else
            {
                hr = E_FAIL;
            }
        }

之后同樣由ProcessColor函數(shù)來處理彩色數(shù)據(jù)：

void CColorBasics::ProcessColor(INT64 nTime, RGBQUAD* pBuffer, int nWidth, int nHeight) 
{
    // 計(jì)算和顯示幀率、時(shí)間
    if (m_hWnd)
    {
        if (!m_nStartTime)
        {
            m_nStartTime = nTime;
        }

        double fps = 0.0;

        LARGE_INTEGER qpcNow = {0};
        if (m_fFreq)
        {
            if (QueryPerformanceCounter(&qpcNow))
            {
                if (m_nLastCounter)
                {
                    m_nFramesSinceUpdate++;
                    fps = m_fFreq * m_nFramesSinceUpdate / double(qpcNow.QuadPart - m_nLastCounter);
                }
            }
        }

        WCHAR szStatusMessage[64];
        StringCchPrintf(szStatusMessage, _countof(szStatusMessage), L" FPS = %0.2f    Time = %I64d", fps, (nTime - m_nStartTime));

        if (SetStatusMessage(szStatusMessage, 1000, false))
        {
            m_nLastCounter = qpcNow.QuadPart;
            m_nFramesSinceUpdate = 0;
        }
    }

    // Make sure we've received valid data 確定接收了有效數(shù)據(jù)
    if (pBuffer && (nWidth == cColorWidth) && (nHeight == cColorHeight))
    {
        // Draw the data with Direct2D 繪制服赎、顯示彩色圖
        m_pDrawColor->Draw(reinterpret_cast<BYTE*>(pBuffer), cColorWidth * cColorHeight * sizeof(RGBQUAD));

        // 存儲(chǔ)彩色圖葵蒂，保存為bmp文件
        if (m_bSaveScreenshot)
        {
            WCHAR szScreenshotPath[MAX_PATH];

            // Retrieve the path to My Photos
            GetScreenshotFileName(szScreenshotPath, _countof(szScreenshotPath));

            // Write out the bitmap to disk
            HRESULT hr = SaveBitmapToFile(reinterpret_cast<BYTE*>(pBuffer), nWidth, nHeight, sizeof(RGBQUAD) * 8, szScreenshotPath);

            WCHAR szStatusMessage[64 + MAX_PATH];
            if (SUCCEEDED(hr))
            {
                // Set the status bar to show where the screenshot was saved
                StringCchPrintf(szStatusMessage, _countof(szStatusMessage), L"Screenshot saved to %s", szScreenshotPath);
            }
            else
            {
                StringCchPrintf(szStatusMessage, _countof(szStatusMessage), L"Failed to write screenshot to %s", szScreenshotPath);
            }

            SetStatusMessage(szStatusMessage, 5000, true);

            // toggle off so we don't save a screenshot again next frame
            m_bSaveScreenshot = false;
        }
    }
}
