[Gdal-dev] Re: GXF and Minimum and Maximum support

[N. Farah]

Hi,

I did made the changes on my local file (gxfdataset.cpp) to implement min 
and max functions. I tested the two methods and they are working fine 
(returning the right values).

Just a very tiny contribution:

// Class definition
class GXFRasterBand : public GDALRasterBand
{
.........................................
	virtual double  GetMinimum (int *pbSuccess);
	virtual double  GetMaximum (int *pbSuccess);
};

// Class implementation
double GXFRasterBand::GetMinimum (int *pbSuccess)
{
    GXFDataset	*poODS = (GXFDataset *) poDS;
    GXFInfo_t *gxfInfo = (GXFInfo_t *) poODS->hGXF;

    if( pbSuccess != NULL )
        *pbSuccess = TRUE;

    return gxfInfo->dfZMinimum;
}

double GXFRasterBand::GetMaximum (int *pbSuccess)
{
    GXFDataset	*poODS = (GXFDataset *) poDS;
    GXFInfo_t *gxfInfo = (GXFInfo_t *) poODS->hGXF;

    if( pbSuccess != NULL )
        *pbSuccess = TRUE;

    return gxfInfo->dfZMaximum;
}
