Not quite sure why this change will make any difference. Will this work with:
!!pParams->GetIntegerFor(...)?

Because in c++ the || operator yields a bool.  If it weren't there, we'd need to
be explicit with the !!.

     if (!m_pDecoder) {
       bool bTransform = false;
       int comps;
       int bpc;
       CCodec_JpegModule* pJpegModule = CPDF_ModuleMgr::Get()->GetJpegModule();
       if (pJpegModule->LoadInfo(src_data, src_size, &m_Width, &m_Height, &comps,
                                 &bpc, &bTransform)) {
         if (m_nComponents != static_cast<uint32_t>(comps)) {
           FX_Free(m_pCompData);
           m_pCompData = nullptr;
