Re: using cvFileStorages

Didnt notice any of your previous mails about filestorages,.

I figured it out from the documentation:
For storing and retrieving floating point raw data:

Storing data onto file:
==================================================================
    CvFileStorage *fs;
    fs = cvOpenFileStorage( "Data.xml", 0, CV_STORAGE_WRITE);
    cvWriteRawData( fs, data_ptr, data_length, "f");
    cvReleaseFileStorage (&fs);
==================================================================


Retrieving data from file:
==================================================================
    CvFileStorage *fs;

    fs = cvOpenFileStorage( "Data.xml", 0, CV_STORAGE_READ);
    cvReadRawData( fs, cvGetRootFileNode( fs ), data_ptr, "f" );
    cvReleaseFileStorage (&fs);
==================================================================

Refer docs for more information and option on filestorages.
