[gdal-dev] Problems writing big tiff image with RasterIO function

[Jorge Martin]

 Hello,

      I am using an old version of the gdal library: 1.4.4.

      I have include below the code I used to write the tiff image:



 //-------------------------------------------------------------------------------------

    WriteImage(string aPath, int *myBuffer, int myNumLines, int myNumCols)
    {

    GDALRegister_GTiff();
    GDALDataset  *m_poDataset;
    const char *pszFormat = "GTiff";
    GDALDriver *poDriver;

    poDriver = GetGDALDriverManager()->GetDriverByName(pszFormat);

    if( poDriver == NULL ) return ( 0 );


    char **papszOptions = NULL;

    m_poDataset = poDriver->Create( aPath.c_str(), myNumColumns,
myNumLines,  1, GDT_Byte,
                                                    papszOptions );


    GDALRasterBand  *poBand = m_poDataset->GetRasterBand(1);

     poBand->RasterIO( GF_Write, 0, 0, myNumColumns, myNumLines,
                      myBuffer, myNumColumns, myNumLines, GDT_Int32, 0, 0 );


    GDALClose(m_poDataset);

    return 1;

   }



 //-------------------------------------------------------------------------------------
