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;
}
