Constructor
VipsImagemask_gaussian
Declaration [src]
int
vips_mask_gaussian (
VipsImage** out,
int width,
int height,
double frequency_cutoff,
double amplitude_cutoff,
...
)
Description [src]
Make a gaussian high- or low-pass filter, that is, one with a variable,
smooth transition positioned at frequency_cutoff.
::: tip “Optional arguments”
* nodc: gboolean, don’t set the DC pixel
* reject: gboolean, invert the filter sense
* optical: gboolean, coordinates in optical space
* uchar: gboolean, output a uchar image
::: seealso
vips_mask_ideal().
Parameters
out |
VipsImage |
Output image. |
|
| The argument will be set by the function. | |
| The called function takes ownership of the data, and is responsible for freeing it. | |
width |
int |
Image size. |
|
height |
int |
Image size. |
|
frequency_cutoff |
double |
Frequency threshold. |
|
amplitude_cutoff |
double |
Amplitude threshold. |
