Mapinfo driver always specify the background color of polygons.

[dev@…]

Using Mapinfo driver,the background color is always defined for each polygon even if this color was defined as 'None' in mapinfo (for semi transparent filling).

I think that the function "ITABFeatureBrush::GetBrushStyleString()" should be modified as follow:

const char *ITABFeatureBrush::GetBrushStyleString()
{
    const char *pszStyle = NULL;
    int    nOGRStyle  = 0;
    char szPattern[20];
    szPattern[0] = '\0';
    if (m_sBrushDef.nFillPattern == 1)              nOGRStyle = 1;
    else if (m_sBrushDef.nFillPattern == 3)      nOGRStyle = 2;
    else if (m_sBrushDef.nFillPattern == 4)      nOGRStyle = 3;
    else if (m_sBrushDef.nFillPattern == 5)      nOGRStyle = 5;
    else if (m_sBrushDef.nFillPattern == 6)      nOGRStyle = 4;
    else if (m_sBrushDef.nFillPattern == 7)      nOGRStyle = 6;
    else if (m_sBrushDef.nFillPattern == 8)      nOGRStyle = 7;

    if ( m_sBrushDef.bTransparentFill ) // don't specify the background color
      pszStyle=CPLSPrintf("BRUSH(fc:#%6.6x,id:\"mapinfo-brush-%d,ogr-brush-%
d\")",
      m_sBrushDef.rgbFGColor,
      m_sBrushDef.nFillPattern,nOGRStyle);
    else
      pszStyle=CPLSPrintf("BRUSH(fc:#%6.6x,bc:#%6.6x,id:\"mapinfo-brush-%d,ogr-
brush-%d\")",
      m_sBrushDef.rgbFGColor,
      m_sBrushDef.rgbBGColor,
      m_sBrushDef.nFillPattern,nOGRStyle);
     return pszStyle;
}

correct before 1.2.0 release.

This seems to be implemented perhaps in year 2006 in file /trunk/gdal/ogr/ogrsf_frmts/mitab/mitab_feature.cpp from rows 8598 ->
