C++ (Cpp) CalcDIBInfoSize Examples

Example #1

File: Capture.cpp Project: ChenglongWang/TVTest

bool CCaptureImage::LockData(BITMAPINFO **ppbmi,BYTE **ppBits)
{
    if (m_hData==NULL || m_fLocked)
        return false;

    void *pDib=::GlobalLock(m_hData);
    BITMAPINFO *pbmi;

    if (pDib==NULL)
        return false;
    pbmi=static_cast<BITMAPINFO*>(pDib);
    if (ppbmi!=NULL)
        *ppbmi=pbmi;

        *ppBits=static_cast<BYTE*>(pDib)+CalcDIBInfoSize(&pbmi->bmiHeader);
    m_fLocked=true;

}

Example #2

File: Capture.cpp Project: ChenglongWang/TVTest

{
    SIZE_T InfoSize,BitsSize;

    InfoSize=CalcDIBInfoSize(&pbmi->bmiHeader);

    if (m_hData!=NULL) {
        BYTE *pData=static_cast<BYTE*>(::GlobalLock(m_hData));

        if (pData!=NULL) {
            ::CopyMemory(pData,pbmi,InfoSize);
            ::CopyMemory(pData+InfoSize,pBits,BitsSize);
