Properties
color
“color” gdouble
If type is gaussian, this means the standard deviation.If type is bilateral, this means the color-sigma. If zero, Default values are used.
Flags : Read / Write
Default value : 0
height
“height” gint
Height of the area to blur (in pixels).
Flags : Read / Write
Default value : 2147483647
kernel-height
“kernel-height” gint
The gaussian kernel height (must be positive and odd).
Flags : Read / Write
Default value : 3
kernel-width
“kernel-width” gint
The gaussian kernel width (must be positive and odd).If type is median, this means the aperture linear size.Check OpenCV docs: http://docs.opencv.org/2.4/modules/imgproc/doc/filtering.htm
Flags : Read / Write
Default value : 3
position-x
“position-x” gint
Starting x position for blur (in pixels).
Flags : Read / Write
Default value : 0
position-y
“position-y” gint
Starting y position for blur (in pixels).
Flags : Read / Write
Default value : 0
spatial
“spatial” gdouble
Only used in bilateral type, means the spatial-sigma.
Flags : Read / Write
Default value : 0
width
“width” gint
Width of the area to blur (in pixels).
Flags : Read / Write
Default value : 2147483647
