示例#1

文件： BackgroundSuppressionShell.cpp 项目： Siddharthk/coan

DataAccessor BackgroundSuppressionShell::getCurrentFrameAccessor() const
{
   if(mpRaster == NULL)
   {
      return DataAccessor(NULL, NULL);
   }
   RasterDataDescriptor *pDesc = static_cast<RasterDataDescriptor*>(mpRaster->getDataDescriptor());
   VERIFYRV(pDesc != NULL, DataAccessor(NULL, NULL));
   FactoryResource<DataRequest> request;
   VERIFYRV(request.get() != NULL, DataAccessor(NULL, NULL));
   request->setInterleaveFormat(BSQ);
   DimensionDescriptor band = pDesc->getBands()[mCurrentFrame];
   request->setBands(band, band, 1);
   return mpRaster->getDataAccessor(request.release());
}
