int im_remainder( IMAGE *in1,
IMAGE *in2, IMAGE *out )
int im_remainderconst( IMAGE *in, IMAGE *out, double c )
int im_remainderconst_vec( IMAGE *in, IMAGE *out, int n, double *c )
im_remainderconst(3) calculates the remainder after integer division of in by the constant c. The output type is the same as the type of in unless in is float or complex, in which case the output type is signed integer.
im_remainderconst_vec(3) works as im_remainderconst(3) , but lets you specify a constant per band.
