VipsImagefreqmult
Declaration [src]
int
vips_freqmult (
VipsImage* in,
VipsImage* mask,
VipsImage** out,
...
)
Description [src]
Multiply in by mask in Fourier space.
in is transformed to Fourier space, multiplied with mask, then
transformed back to real space. If in is already a complex image, just
multiply then inverse transform.
