Revision history [back]

In file, bgfg_gmg.cpp, line 375,

int nfeatures = nfeatures_row[x];

The variable should be changed by function, 'insertFeature', otherwise 'nfeatures_' is always zeros.

Is it right?

Should I change this line into:

int& nfeatures = nfeatures_row[x];'

In file, bgfg_gmg.cpp, line 375,

The variable should be changed by function, 'insertFeature', otherwise 'nfeatures_' is always zeros.

Is it right?

Should I change this line into:

int& nfeatures = nfeatures_row[x];'

because the function, 'insertFeature' is defined as:

static bool insertFeature(int color, float weight, int* colors, float* weights, int& nfeatures, int maxFeatures)

If we used line one, it will update by the variable, 'nfeatures', not refer to 'nfeatures_'.
