Namedt_fp_mindensity - retrieve the global minimum fingerprint density
Generic Prototypedt_fp_mindensity(void) => dt_Real
C Prototype#include "dt_finger.h"
FORTRAN Prototypeinclude 'dt_f_finger.inc'
DescriptionThis function is obsolete, as of version 4.42. The global minimum density value is only used by the obsolete functions dt_fp_fingerprint(), and dt_fp_fold().
Returns the global minimum fingerprint density. This value limits fingerprint folding. The density is calculated by dividing the number of 1's set by the total number of bits in the fingerprint. Attempts to fold a fingerprint whose density exceeds the minimum density will be silently ignored (see dt_fp_fold(3)).
Return ValueReturns a real containing the minimum density value.
