Description [src]
Optional arguments:
nodc: don’t set the DC pixelreject: invert the filter senseoptical: coordinates in optical spaceuchar: output a uchar image
Make a gaussian high- or low-pass filter, that is, one with a variable,
smooth transition positioned at frequency_cutoff.

Parameters
out-
Type:
VipsImageOutput image.
The argument will be set by the function. The caller of the function takes ownership of the returned data, and is responsible for freeing it. width-
Type:
intImage size.
height-
Type:
intImage size.
frequency_cutoff-
Type:
doubleFrequency threshold.
amplitude_cutoff-
Type:
doubleAmplitude threshold.
...-
Type:
NULL-terminated list of optional named arguments.
